qPCR – Hard Clam NGS Primer Checks

Ran a qPCR to evaluate a large batch of primers (40 sets) that were ordered per Steven, based off of the most recent SOLiD run (samples submitted 3/10/2011; see Dave’s notebook for more info). Pooled cDNA (2uL from each individual; from 20110511) was used. Master mix calcs are here. Plate layout, cycling params, etc. can be found in the qPCR Report (see Results). The list of primers tested is available in the Primer Database and consist of SR IDs 1233 – 1312. For brevity, samples were only labelled with the corresponding contig number.

Results:

Reverse Transcription – Hard Clam Gill DNased RNA (from 20110509)

Performed reverse transcription on DNased RNA from the hard clam vibrio tubiashii challenge experiment (see Dave’s Notebook 5/2/2011), following the Promega M-MLV RT protocol with ~1ug of DNAsed RNA. Master mix calcs are here. Reactions were done in a plate. cDNA was diluted 1:4 with H2O.

DNase – Hard Clam Gill RNA (from earlier today)

DNased 5ug of RNA from each sample with Ambion’s Turbo DNA-free Kit, according to the manufacturer’s rigorous protocol. Samples were spec’d and stored @ -80C in the “Hard Clam V.t. Experiment RNA” box.

Results:

Due to lack of a positive control (and lack of primers known to amplify gDNA), these DNased RNA samples will NOT be checked to verify elimination of gDNA carryover at this time. Will proceed with making cDNA for qPCR anyway.

RNA Isolation – Hard Clam Gill Tissue from Vibrio Experiment (see Dave’s Notebook 5/2/2011)

Isolated RNA in 1mL of Tri-Reagent according to the manufacturer’s protocol. Also, finished RNA isolation of samples that were started 20110506. Samples were resuspended in 50uL 0.1%DEPC-H2O and spec’d.

RNA Isolation – Hard Clam Gill Tissue from Vibrio Experiment (see Dave’s Notebook 5/2/2011)

Isolated RNA in 1mL of Tri-Reagent according to manufacturer’s protocol. Samples were precipitated with isopropanol and stored over the weekend @ -20C. Will conclude isolation on Monday. The samples isolated were:

MA 1-11

MA Vt 1-11

Received Hard Clam Samples and Live Clams from MBL

Received 82 gill samples in RNA Later in 3 microfuge tube racks from MBL (Scott Lindell). Samples were catalogued, boxed (1 box) and stored at -80C.

The live clams were received in two bags one containing ~12 labelled MA4 and one containing ~12 labelled BX1. Clams were NOT counted and the quantity may be different. Clams were temporarily stored @ 4C.

Received Hard Clam Samples from Rutgers

30 gill tissue samples in RNA Later from CA, MA, & MAX each.

30 hemolymph samples (in RNA Later?) from CA, MA, & MAX each.

Presumably these are from the same individuals. Tubes were boxed (a total of 3 boxes), labeled and stored @ -80C.

Here is a note included from Emily with the samples .
