Assays Protein Assays

Pierce™ 660 nm Protein Assay is a ready to use, detergent- and reducing agent-compatible assay reagent to quickly measure (A660 nm) total protein concentration compared to a protein standard.


  • Can be performed in either a test tube or microplate format
  • Works with wide range of detergents and reducing agents than other dye-based assays
  • Single reagent with a simple mix-and-read protocol; no working reagent to prepare
  • Requires only 10 µl for microplate or 100 µl for the test tube procedures


Pierce™ 660 nm Assay is more linear than Coomassie-based Bradford assays and compatible with higher concentrations of most detergents, reducing agents and other commonly used reagents. The accessory Ionic Detergent Compatibility Reagent (IDCR) provides for even broader detergent compatibility, making this one of the only protein assays that is suitable for samples containing Laemmli SDS sample buffer with Bromophenol blue.


Delivery information: Kit includes Pierce™ 660 nm Protein Assay Reagent (450 ml) and albumin standard pre-diluted set (7×3,5 ml). Pierce™ 660 nm Protein Assay Reagent is also available separately.
