General description

This product is a mixture of protease inhibitors with a broad specificity for the inhibition of serine, cysteine, aspartic proteases and aminopeptidases. It is designed to be used as a supplement to tissue culture medium for the prevention of secreted proteins degradation. The product has been found to be non-toxic after a 48 hours exposure to the following adherent cell lines: A431, CHO, COS, HepG2, and HeLa, and to following non-adherent cell lines: Jurkat and HL-60. This cocktail is supplied as a ready-to-use solution using a proprietary non-freezing formulation. ReadyShield PIC0006 is a non-freezing formulation that contains the same inhibitors as is the DMSO based cocktail P1860.
