	I need pure S-protein (bovine pancreatic ribonuclease S-protein i.e.
residues 20-124 of RNase-A) for crystallography experiments.  The stuff from
Sigma is at least 2 bands (1-2 kD apart) on an SDS phast-gel. Does anyone
know of an alternate vendor for this protein? I am not interested in the 
ribonuclease-S COMPLEX. I just need the larger (S-protein) fragment...please
e-mail me at sinharoy at with info/advice. Thanks!
