Dear All, I have searched the archives and would like more information about reproducing robot tray hits using 24-well hand trays. I reproducibly get crystals when I use small volumes (0.5 ul) in 3-well intelliplates but only precipitate in 1-2 ul sitting drops in 24-well hand plates. What parame

[ccp4bb] [off-topic] solubility after myristoylation

2011-10-07 Thread Matthew Lalonde
I am trying to myristoylate a protein (via the N-terminal glycine) using purified recombinant N-myristoyltransferase and myristoyl-CoA. However I am having problems with solubility. I can solubilize the unmyristoylated protein in 250 mM NaCl and 25 mM HEPES at pH 8.0. I wonder if anyone on this li
