Chlorophenol red β-D-galactopyranoside (CPRG) is a colorimetric substrate for β-galactosidase.^1,2 Upon enzymatic cleavage by β-galactosidase, chlorophenol red is released, which can be quantified by colorimetric detection at 570 nm as a measure of β-galactosidase activity.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such as vortex, ultrasound or hot water bath can be used to aid dissolving.
