Translation Protocol

printer Get a printable version of this protocol (requires Adobe Acrobat

A typical 10 ul reaction contains:
35mM Tris-acetate, pH 8.0
190mM K (glutamate)
30mM NH4OAc
2mM DTT
12mM Mg (Ac)2
40(M 19 aa's - met
2mM ATP
5mM each CTP, UTP, and GTP
20mM phosphoenol pyruvate
1mg/ml E. coli tRNA
35mg/ml PEG 8000
20ug/mL folinic acid
2mM IPTG
0.5ug DNA template
1ul 35S Met
3ul bacterial lysate

This is incubated at 37°C for 45 min. for coupled T1 andT2

Note: Each batch of S-30 must be optimized for Mg (OAc)2 and K(glutamate)concentration.
