Bio-Rad Protein Assay Kit II #5000002EDU

Choose the Bio-Rad Protein Assay for simple, accurate measurement of total protein. This colorimetric assay based on the Bradford method is compatible with many common lab reagents.

Flexible assay formats:

• Use the standard assay for protein concentrations between 200 and 1,400 µg/ml (20–140 µg total protein)
• Use the low-concentration assay for protein concentrations < 25 µg/ml (1–20 µg total protein)
• Use 96-well microplates for rapid assays

Product Options
