media type="custom" key="7815287" The spreadsheet was public, so anybody should have been able to view or edit it. Maybe it's a compatibility issue between UW and Gmail. But I've since made it private and tried adding everybody in the oyster group privately. Hopefully, it works. 1291891583

RNA concentrations were normalized again for a final end concentration of 2 ug using the following equations:
 * December 2, 2010**

1. (RNA conc ng/uL)/1000= RNA conc ug/uL 2. (RNA conc ug/uL) * X = 2 ug ---> X = 2 ug/(RNA conc ug/uL) where X equals the amount of stock RNA to add to the reverse transcription for RNA

The following google doc is the data and calculations for each sample: https://spreadsheets.google.com/ccc?key=t7fhoi_PCVo_3vcUnIIPQAA&hl=en#gid=0
 * Note because final RNA amounts vary for each sample the amount of nuclease free H2O will vary as well and was calculated by water=(5-RNA)+4 and these calculations are included int the above spreadsheet as well***

All samples were reverse transcribed using the following protocol:


 * 1) Thaw and mix RNA stock tube by inverting
 * 2) Add pre-calculated stock RNA, 1 μl oligo dT, and individual amount of nuclease free H    2  0 based off of RNA amount added in a 0.5 ml PCR tubes
 * 3) Return RNA stock sample to ice
 * 4) Incubate mixture for 5 min at 70°C on the thermocycler then put tube on ice till cool.
 * 5) Briefly centrifuge sample tube
 * 6) Add 5 μl of M-MLV 5X Reaction Buffer, 5 ul of dNTPs, 1 μl of M-MLV RT, 4 μl of nuclease free H 2 O to sample tube.
 * 7) Incubate mixture for 60 minutes at 42°C and then heat inactivate at 70°C for 3 minutes on the thermocycler.

After reverse transcription each sample was transferred to its own individual labeled 1.5 mL microcentrifuge tube and an additional 225 uL of nuclease free water was added for a final dilution so enough product is available for qPCR's of three different genes in duplicates

All samples were returned to the -20°C for storage

RNA was extracted from oyster gill tissue from Big Beef Creek. RNA concentrations were recorded on a Nanodrop Spectrophotometer. Most of our RNA concentrations were at or around 3000 ng/ µL. From those initial concentrations, using (C1)(V1)=(C2)(V2), we calculated how much concentrated RNA is needed to make a 500 µ L of 200 ng/ µ L RNA stock. The math was checked multiple times, but after making dilutions of Control 1A and 2A, we again measured RNA concentration. We got readings of 20 ng/ µ L and 40 ng/ µ L, respectively. We didn't want to lose any more time by continuing to make dilutions. After talking to Steven and Caroline, we decided to DNase 50 µL of our concentrated RNA extract and then quantify our RNA concentrations again. Turbo Free DNase kit/protocol was used. The concentrations are in the range of 500-1800 ng/ µL. Currently, they are labeled and sitting in the -80 C freezer. We need to thaw them, centrifuge them, extract the liquid (which should now be purely RNA suspended in 0.1% DEPC). We can run qPCR with this RNA stock. In order to do so, we need between 1 and 10 µg of RNA. We need to calculate how many µL of stock we need to get between 1 and 10 µg of RNA.
 * November 30, 2010-December 1, 2010**

The next step is to extract only the suspended RNA and to leave behind the broken down DNA at the bottom of the tubes. A lot of 4B Vt sample evaporated during the DNase incubations.

Here are the concentrations [RNA] (ng/µL) || Cu [RNA] (ng/µL) || Vt [RNA] (ng/µL) || Cu+Vt [RNA] (ng/µL) || (not much sample is left but there's plenty of RNA in what we have) || 1030.1 ||

__Molecular projects__
 * Dave M**. - I will be looking at changes in //V. tubiashii// gene expression under the different experimental conditions of seawater, seawater + Cu, seawater + oyster, and seawater + oyster + cu. I will need to extract RNA from the water filter samples collected on 11/19/10


 * Ross** - Looking at methylation at five sites as well as globally. Need to extract DNA from the gill tissue we collected.

Paul- Western Blot

Jason - I'm looking at Metallothionein IV gene expression in oyster gill tissue, which is full of hemocytes.

Sammi - I will be looking at HSP 70 gene expression in oyster gill tissue

**November 19, 2010** Tissue Sampling *Can someone expand on this that was there the whole time? I was running around a lot and dont have a grasp on the details... user:dmetzger1

Today the group is collecting oyster tissues from the Cu/Vt challenge that has been going on all week. Tissues to be collected are the gill (for its concentration of hemocytes), mantle (mostly for DNA/methylation analysis), hemolymph (alternative source for hemocytes), and size dimensions (Lenth, width, height) of the oysters.

//Vt// culture from 11/17/10 was spun down at 4,800rpm for 20min in a swing bucket rotor. Remove supt. and resuspend //Vt// in 1L of filtered seawater. Spin again 4,800rpm 20min. Remove supt. and resuspended in 110ml filtered seawater (11 treatments, 10ml/treatment) Spec at OD550. Spec Reading = 0.750

Calculating CFU Estimated CFU by assuing 1U at OD550 = 5x10^8 cfu/ml 0.750 x (5x10^8) = 3.75x10^8cfu/ml 3.75x10^8cfu/ml x 10ml/sample = 3.75x10^9cfu
 * 3.75x10^9cfu = total amount of //Vt// added to each bucket**

 * 7.5x10^5cfu/ml** **= concentration of //Vt// in each bucket**

DISPOSAL of V. tubiashii exposed oysters: Discard tissue and shell waste in autoclavable biohazard bags which are in the lab. After sampling, get Caroline. I will take the waste to FSH to be autoclaved. Once the exposed oysters have been autoclaved I will put them in MER -20C walk-in for KH to dispose of. user:storercg

ATTENTION!! While updating the methods section of the google doc I noticed the math for the ppm calculations of Copper sulfate were off 100 fold. Instead of adding the "EPA relevant" 1.3ppm, 130ppm was added. We need to do some research ASAP on what this means, is it ecologically relevant? Are there places with Cu concentrations this high? Fortunately we will still have the vibrio challenge, but we need to determine as quickly as possible if the copper treatment will generate meaningful data... user:dmetzger1 <--I will work on this and find out what I can and post my findings tomorrow morning- ** [|SammiBrombacker] ** Yesterday 7:26 pm

 I checked the calculations we did and I'm still getting 6.5 mg to 5 liters comes out to 1.3 ppm I think i must be doing it wrong then what are the correct calculationsuser:ddb4

** Tending to the //Vt// cultures... ** user:dmetzger1
 * After o/n incubation of 100mL cultures of //Vt and Vp// at 37degrees C, it looks like the //Vt// has not grown at all. **

Started three new 5ml cultures of //Vt// One culture was inoculated from a //Vt// plate into the LB (1%NaCl) that was prepared yesterday Another from the same plate but into Marine Broth and the third was from a -80 glycerol stock into the LB made yesterday.

NOTE: After innoculation, I added another 10g (1%) NaCl to the LB, split it into two 500ml aliquots, and reautoclaved.

At the end of the day today, I will take all of my //Vt// cultures and combine them into one of the 500ml flasks of LB, and add the //Vp// culture that is growing so well into the other 500mL aliquot of LB

__<span class="membersnap" style="background-color: #ffffdd; color: #999999; padding: 2px 4px 3px; white-space: nowrap;"> **Details:** __ __<span class="membersnap" style="background-color: #ffffdd; color: #999999; padding: 2px 4px 3px; white-space: nowrap;"> **There was a minor disaster this morning when I went to put the oysters into the basement system. Apparently the recirculating rates for the two sumps was not even which resulted in all of the water from one sump being pumped into the other. The problem is two fold:** __ __<span class="membersnap" style="background-color: #ffffdd; color: #999999; padding: 2px 4px 3px; white-space: nowrap;"> **1. One of the sumps was dry and not being held at 12 degrees.** __ __<span class="membersnap" style="background-color: #ffffdd; color: #999999; padding: 2px 4px 3px; white-space: nowrap;"> **2. The other sump was too full which lifted and tipped the buckets over.** __

__<span class="membersnap" style="background-color: #ffffdd; color: #999999; padding: 2px 4px 3px; white-space: nowrap;"> **All tipped buckets were drained and refilled with pure sea water. Half of the water from the full sump was pumped back to the dry pump. The chiller was disconnected from one of the sumps so it is now only circulating water for one system. I hooked up another chiller to the other system. This chiller is slighty different in that water is not flowing through it, instead there is a cooled wired that chills the water directly in the sump. This may or may not induce a tank effect. The pump was left in the water of the coil chiller to help mix the sump water.** __

__<span class="membersnap" style="background-color: #ffffdd; color: #999999; padding: 2px 4px 3px; white-space: nowrap;"> **Result: everything seems to be working for the moment and both sumps are holding at ~12-13 degrees C.** __

__<span class="membersnap" style="background-color: #ffffdd; color: #999999; padding: 2px 4px 3px; white-space: nowrap;"> **FINALLY the oysters can be put into buckets. Four oyster were put in each bucket. Blue/green label are from Big Beef Creek and Red labels are from the park. Treatments are separated so that all buckets that will eventually contain //V.tubiashii// will be kept together. Extra oysters were put in separate buckets and placed in the system with the coiled chiller.** __

__<span class="membersnap" style="background-color: #ffffdd; color: #999999; padding: 2px 4px 3px; white-space: nowrap;"> **No food has been added to the buckets.** __ __<span class="membersnap" style="background-color: #ffffdd; color: #999999; padding: 2px 4px 3px; white-space: nowrap;"> **Sammi will check on the systems before she leaves tonight.** __

Low tides were a +7 which didnt allow us to collect oyster that were very far out on the tidal flats. Oysters at Big Beef Creak were collected closer to 4pm. ~40 oysters were collected from each site. Oysters were kept in coolers in the back of Steven's truck o/n and transported to the lab on friday morning.** __

Currently we have two large white totes (like the kind they use on fishing boats) that contain 8 buckets each. This gives us a total of 16 buckets which is how many we will need to carry out our 4 treatments in duplicate for each site.** __

__<span class="membersnap" style="background-color: #ffffdd; color: #999999; padding: 2px 4px 3px; white-space: nowrap;"> **At the moment we have seawater in all of the buckets with airstones only. There is no recirculation/filtration happening on the buckets. The waterbath totes have fresh water that is circulating through a chiller. Initial temperature measurements have one waterbath at 17 degrees C and the other at 19 degrees C. I will check the temps before I leave tonight to see if they are dropping towards our target temp of 12 degrees C.** __
