[ccp4bb] Reagent Grade from Hampton

2009-03-26 Thread Haridasan Namboodiri
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

Thanks all for the suggestion. I have ordered the additional salts from Hampton. I still have about 600uL of the original solution in the block. BTW, the hits obtained were in two different conditions with the two salts. They were PEG/Ion HT screen A7 and D6. I am keeping my fingers crossed. Sin

[ccp4bb] Design Constructs

Hello I am designing a protein construct for structural biology. It is a protein kinase which has not been crystallized earlier. I was comparing the kinase domains of other closely related family members characterized biochemically vs crystallization constructs. For crystallography constructs,
