gDNA was isolated using 500uL of 10% Chelex. Samples were heated @ 95C for 1hr w/periodic vortexing. Samples were then spun 16,000g for 5mins @ 4C. Stored @ -20C in Bay x Sea Scallop Project Box.

PCR – Dungan Isolates http://onsnetwork.org/kubu4/2009/01/07/pcr-dungan-isolates/ http://onsnetwork.org/kubu4/2009/01/07/pcr-dungan-isolates/#comments Wed, 07 Jan 2009 23:07:00 +0000 http://onsnetwork.org/kubu4/?p=1225

Samples (in Chelex) were vortexed and heated @ 95C for 30mins with periodic vortexing. Tubes were spun max speed @ 4C for 2 mins to pellet Chelex. Set up PCR using Immomix master mix. Anealing temp. = 56C. PCR set up here.

Lane 1 – 100bp ladder

Lane 2 – xCvC-11t

Lane 3 – xCvC-12t

Lane 4 – xCvC-17t

Lane 5 – VNTc-12-C1/G10

Lane 6 – BC05Ca-18t/H5

Lane 7 – VATm-1.2t

Lane 8 – VNTc-1.5t

Lane 9 – Neg. Control

Results: PCR seems to have worked for some of the samples. The bottom-most band in lanes 4, 5, 6, 9, & 10 were cut out and stored in “Sam’s Misc. -20C Box”. Date is 1/8/2009, since this PCR ran O/N.

PCR – Dungan Isolates http://onsnetwork.org/kubu4/2009/01/06/pcr-dungan-isolates-2/ http://onsnetwork.org/kubu4/2009/01/06/pcr-dungan-isolates-2/#comments Tue, 06 Jan 2009 23:09:06 +0000 http://onsnetwork.org/kubu4/?p=1227

All samples , except xCVC-11t, are already in Chelex. For xCvC-11t, pipetted a shunk of cells/tissue from source tube. Volume of liquid (EtOH) was ~75uL. Added this to screw cap tube containing 300uL of 10% Chelex solution. Vortexed and incubated @ 95C for 30mins. Vortexed and incubated other samples at 95C for 5mins. Set up PCR with AmpliTaq. Anneal temp. = 53C. PCR set up here.

Lane 9 – Neg. Control

Results: Ladder is degraded and there are no bands in any lane. Will repeat and try to duplicate Steven’s results from 20080916.
