OZ Biosciences ONPG assay kit is ideal to quantify high expression level of beta-Gal. The levels of active beta-Gal expression can be quickly measured by its catalytic hydrolysis of ONPG (o-nitrophenyl-beta-D-galactopyranoside) substrate to a bright yellow product (Absorbance at 405-420nm).
LacZ is one of the most frequently reporter gene used in transfection experiments. The LacZ encoded protein (beta-galactosidase, beta-Gal), is very stable, resistant to proteolytic degradation and easily assayed.

All the necessary reagents are provided in this assay kit and offer a rapid, simple and sensitive method to quantify spectrophotometrically the enzyme expression level in LacZ transfected cells.

- Convenient for all transfection assays
- Suitable for cultured cells and tissues
- Simple, rapid and easy-to-use
- Economical
- Optimized with stable buffers

For research use only.
