Probe Production[edit]
Dr Zhang had a good suggestion to do biotin probe production for each of the barcode oligos. I'll do this as a standard reaction without the bead oligos. I can then do the biotin attachment and oligo melting after that. This will allow me to separate the imaging steps from the actual emulsion PCR which will be more important for
Protocol[edit]
- qPCR
- Make 4.2X (1X) master mix with the following reagents
- 4.2 (1) uL 10 uM AP1v4U
- 4.2 (1) uL 10 uM BiotinU
- 75.6 (18) uL nfH2O
- 105 (25) uL 2X SYBR Fast
- Add 45 uL master mix to each sample
- Add 5 uL barcode oligo according to plate layout File:20170505-PlateLayout-BiotinOligoProduction.png
- qPCR Cycles
- 95C 3 min
- 95C 3 sec
