I am looking for a phosphatidylinositol specific phospholipase C
(PI-PLC), until now I was working with PI-PLC from Boehringer Mannheim
(<italic>Bacillus cereus</italic>) to specifically release
phosphatidylinositol-anchored membrane proteins (no release of PC, PS,
PE, phosphatidylglycerol, phosphatidic acid or sphingomyelin), but this
product is no longer available. Do you know an other company where I
can buy this phospholipase (the Sigma PI-PLC was not pure enough)?
thank you for your help,
