New Oligo in the Lab

By UNM CC UNM CC

Notes Stocks should be handled with care to ensure that they are not contaminated with PCR product or plasmid DNA that might be prevalent in the laboratory. For this reason they are handled only in the pre-PCR area with gloves, aerosol resistant tips, and DNAse/contamination-free solutions. Oligo concentrations are typically expressed in terms of moles, […]

Alcohol Precipitation of DNA

By UNM CC UNM CC

(Ref: Molecular Cloning A8.12) The major considerations in using alcohol to precipitate DNA are: Temperature: -20°C is optimal, but 0°C can be used for >20 ng/mL Amount: For small amount of DNA (<100 ng, i.e. too little to reliably see a pellet) the use of glycogen (1 µL of a 20 mg/mL stock, (Roche 10901393001) […]

A/B/C Random Amplification Protocol  

By UNM CC UNM CC

Adapted from Bohlander et al. Genomics 13 (1992). (modified by D. Schubeler, L. Loo) Genomic DNA will be randomly primed with a sequence tagged oligonucleotide for 2 cycles.  This will create random genomic products with a specific tag at both ends. These products will then be amplified and labeled with a sequence specific dye primer. […]
