| * The current state of our lysis protocol for RNA precipitation:<br> | |
| --------------------------------------------------------------<br>
| |
| a) Base formulation: 2.85M Gu-HCl (final)+ 100 ug Proteinase K + 0.015% Tween 20 <br>
| |
| b) Prior to precipitation: +100 ug glycogen, +200mM sodium acetate pH 4.0 (final), +50% isopropanol (final) <br>
| |
| <br>
| |
| 1) Input = 200 uL of either purified RNA / blood + spiked variations / Versant serum + spiked variations <br>
| |
| 2) Lysis buffer ~ 500 uL total <br>
| |
| 3) 60 C digestion for 30 min / spin-down for blood only to get rid of particulates<br>
| |
| 4) Add sodium acetate pH 4.0 (200 mM final) + glycogen (100 ug) <br>
| |
| 5) Add 700 uL (~ 1 vol) of isopropanol to make it 50% isopropanol final <br>
| |
| 6) Hard spin-down / 2x wash pellet with 75% EtOH <br>
| |
| 7) Resuspend pellet in 60 uL water <br>
| |
| 8) Incubate @ 50C, 10 min for full dissolution <br>
| |

| -- In the context of blood lysis: ------------ <br>
| |
| * Working with fresh blood and new lysis buffers, running through straws and testing flow-throughs. (SAB) <br>
| |
| * Testing potential filtering method after lysis before introduction to monolith to prevent clogging. (JT/SAB) <br>
| |
| * Have ordered Chelex 100 resin from Biorad and see if we can chelate out Fe2+ / Fe3+ before RNA precipitation (SAB / AF) <br>
| |
| <br>
| |
| -- In the context of Versant / Seracare (serum-only) lysis: ------------ <br>
| |
| * Did one round of +SiO2 (pre-acid washed glass beads) test extraction with our Gu-HCl based lysis buffer. Also did one round of silanized SiO2 bead with our Gu-HCl based lysis buffer. Waiting for PCR results (AF).
| |
| <br>
| |
| -- Real-time PCR / Cloning / ssDNA /other stuff ------------ <br>
| |
| * Have ordered Taqman MGB probe for our G100/G25 HIV-gag locus (AF).
| |
| | |
| * Restreaked clones for exogenous RNA controls where the synthetic RNA template is of non-human, non-HIV origin... the gene segment to-be-cloned actually comes from the cdc6 gene in Xenopus tropicalis (the Western clawed frog). Will digest and find isolate on Wed.(AF).
| |
| * Will try time-course on full pol ssDNA synthesis to minimize E. coli lysis during M13 transfection (AF)<br>
| |
| * Ran Boom buffer through monolith only straws. Will bDNA the eluent this week.(JZ)<br>
| |
| * Process flow throughs. (JZ) <br>
| |
| * Chentian - Figuring out a way to do silica channels. First pass: making plug with monolith. <br>
| |
| * ABI Taqman for HIV. Waiting for that to arrive. For LTR instead of gag. (MM) <br>
| |
| * Running bDNA assay on HIV storage in straw at 0, 1, 4, 12 and 24 hours with stablizer, results to come this afternoon. (SAB) <br>
| |
| * Running RNA storage with stablizer at 0, 1, 4, 12 and 24 hours, qPCR down so analysis on hold. (SAB) <br>
