[ccp4bb] My protein precipitates at r.t and dissolves at 4 oC

2012-03-12 Thread Min-Kyu Cho
Hi all, I have a homotetrameric coiled-coil domain sample with 45aa per each. While I store this sample at 4oC, the sample looks clear w/o any particles. But when I took out the sample to my bench at r.t, I can see there are precipitates (as stack of needle like particles) at the bottom of
