Description
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
See the Bio-Rad Protein Assays product page for individual protein standards, documentation, and more information.
