Kras G12D Conditional PCR
(multiplex & single allele)

NOTE: this reaction looks for the presence of the stop cassette NOT the mutation.

Samples must be sequenced to look for mutation.

The guarantee for this PCR to work is to use

"Red Taq Ready Mix" from Sigma, cat. no. R2523.

Alternatively, use:

Reaction Mix:

Tail DNA 1.0ul
10x PCR buffer 2.0ul
dt5-(40pmol/ul)* 0.6ul
Uni'-(40pmol/ul) * 0.4ul
SD5'-(40pmol/ul)* 0.2ul
milliQ 14.8ul
Taq (1/25) 1.0ul

*or for single allele reactions use 10pmol primers per reaction

10X PCR Buffer:

500 mM KCl
100mM Tris pH 8.3
15 mM MgCl2
1 mg/ml BSA
2 mM dNTPs
dH20

(store at -20† C)
