GP1 V6 Padlock Probe Production
Overview
- Expansion PCR
- Production PCR
- Exonuclease digestion to generate SS-DNA
- Removal of amplification adapters
- Probe purification by PAGE size-selection
Expansion PCR
- Probe concentration from CustomArray 32.71ng/ul volume 80uL Amount 2.62ug
- Probe size 146bp
Convert ng/ul to nM
- Molar Mass of ssDNA probe: 146bp * (325Da/bp) = 146bp * (325 g/mol/bp) = 47450 g/mol
- (32.71ng/ul * 1*10^6 ul/L) / (47450g/mol) = 689.36nM
- I will use 100nM final concentration for the expansion PCR

Nanodrop
- 10.7ng/ul * 50ul = 535ng
- 120.44nM
