Can any one please help me out with the transformation of Pichia pastoris?
We are trying to express gp96 (glyco protein 96) mutants in pichia pastoris.
I have tried electroporation as well as CaCl2 treatment for the production of competent cells.
But it was of no use
After electroporation, I am adding 1mL of ice cold sterile 1M sorbitol and then incubating them for approximately 3 hours at 30o C and plating them on YPDS + Zeocin plates
I have also tried other methods like addition of 0.5mL sorbitol and 0.5mL of YPD media to the cells immediately after electroporation and then incubate them for 3 hours at 30o C.
Please send me your suggestions so that I can make it work.
