PEPTONE P

Code: LP0049

A peptic digest of meat proteins used in culture media which is bacteriologically tested to the USP Specification for peptic digest of animal tissue. The molecular profile shows the characteristics of peptic hydrolysates, having a shift to higher molecular peptides and the salt content reflects the low pH required for the optimum activity of the enzyme during processing.
It has been used as a replacement for bovine serum in a medium on which Baby Hamster Kidney (BHK) cells were grown. Also incorporated in media to produce interferon.
