Hello,
I am trying to reproduce two hits obtained from the PEG/Ion screen of
Hampton which showed up with 20% PEG3350 and 0.2M K2HPO4/0.2M CaCl2. I
tried optimizations making up my own solutions with the two salts from Sigma
(The PEG is from Hampton). To my surprise, the hits do not translate during
optimizations. I am suspecting the salts. My question is, what grade of Sigma
chmicals would be equivalent to the ones sold by Hampton?
Any other suggestions would be more than welcome.
Regards
Hari
