660 nm Protein Assay

 

Thermo Scientific Pierce 660nm Protein Assay is a ready-to-use, detergent- and reducing agent-compatible assay reagent to quickly measure (A660nm) total protein concentration compared to a protein standard.

 

It is more linear than coomassie-based Bradford assays and compatible with higher concentrations of most detergents, reducing agents and other commonly used reagents.

BCA Protein Assay Reagent

 

Thermo Scientific Pierce BCA Protein Assay Kit is a two-component, high-precision, detergent-compatible assay reagent set to measure (A562nm) total protein concentration compared to a protein standard.

 

It can be used to assess yields in whole cell lysates and affinity-column fractions, as well as to monitor protein contamination in industrial applications.

BCA Protein Assay - Reducing Agent Compatible

 

Thermo Scientific Pierce BCA Protein Assay – Reducing Agent Compatible enables the measurement of protein concentration in samples that contain thiol-reductants dithiothreitol (DTT) and 2-mercaptoethanol (BME).

 

It provides all of the advantages of the original BCA Assay, plus compatibility with disulfide reducing agents at concentrations routinely used in protein sample buffers.

Bovine Gamma Globulin (BGG) Standards

 

Thermo Scientific Pierce BGG Protein Assay Standards are high-quality reference samples for generating accurate standard curves and calibration controls in total protein assays. These bovine gamma globulin (BGG) solutions are protein concentration reference standards for use in BCA, Bradford and other protein assay protocols.

 

BGG is an accepted reference protein for total protein quantitation of purified antibodies or immunoglobulin-rich samples.

Bovine Serum Albumin (BSA) Standards

 

Thermo Scientific Pierce BSA Protein Assay Standards are high-quality reference samples for generating accurate standard curves and calibration controls in total protein assays. These bovine serum albumin (BSA) solutions are protein concentration reference standards for use in BCA, Bradford and other protein assay protocols.

 

BSA is the universally accepted reference protein for total protein quantitation.

Coomassie (Bradford) Protein Assay Kit

 

Thermo Scientific Pierce Coomassie Protein Assay Kit is a ready-to-use, stable formulation of the traditional Bradford assay reagent to measure (A595nm) total protein concentration compared to a protein standard.

 

It includes Coomassie Protein Assay Reagent and a package of Albumin Standard Ampules.

Coomassie Plus (Bradford) Protein Assay

 

Thermo Scientific Pierce Coomassie Plus Protein Assay is a ready-to-use, reducing agent-compatible, improved Bradford assay reagent to quickly measure (A595nm) total protein concentration compared to a protein standard.

 

The Pierce Coomassie Plus Assay Reagent provides increased linearity of response and only half the protein-to-protein variability of other commercial Bradford assay formulations.

Micro BCA Protein Assay Kit

 

Thermo Scientific Pierce Micro BCA Protein Assay is a special 3-component version of our popular BCA Reagents, optimized to measure (A562nm) total protein concentration of dilute protein solutions.

 

The assay is exceptionally linear and exhibits very low levels of protein-to-protein variability.

Modified Lowry Protein Assay Kit

 

Thermo Scientific Pierce Modified Lowry Protein Assay is a stable form of a traditional, 2-component, folin phenol- and copper-based reagent system to measure (A750nm) total protein concentration compared to a protein standard.

 

Although newer protein assay methods provide greater speed and convenience, the Lowry method remains a popular, accurate and useful option for many applications.
