switch to SAP ! shrimp alkaline phosphatase is heat labile and much
easier to handle. In my hands CIP always makes problems. I generally 
just add 0.2 ul of SAP to the digest for 30
minutes and, freeze at -70 to inactivate and... presto !

SAP is a USB product, a company that pays me huge amounts of
money to advertise their products on the net. Just that the
checque didn't arrive yet.
