Dear friends: Some PCR-based protocols include the use of gelatin (around 0.01% per rxn). Can anyone tell me if this is the same product used for microbilogical works? and what is this specifically used for in PCR?. Then, and how it should be prepared for PCR rxn? Thanks a lot for any input. Rina International Potato Center Pathology lab e-mail: rcarhuaz at cgnet.com
