Sample Preparation & Quantitation

Use this simple colorimetric protein assay to measure total protein concentration. Easily adaptable from low to high concentration for rapid 96-well assays. 

The Quick Start Bradford assay kit is a simple one step procedure. with no need to dilute standards for determining the concentration of protein in a solution.

This detergent-compatible protein assay uses a colorimetric method to determine protein concentration following detergent solubilization. The reaction is similar to the well-documented Lowry assay. 

This reducing-agent and detergent-compatible protein assay is a colorimetric assay for protein determination in the presence of reducing agents and detergents. 

Standard 3.5 ml or semimicrovolume 1.5 ml polystyrene cuvettes that are ideal for protein assays.

Kits designed for removal of salts, high-abundance proteins, and other contaminants are offered. They incorporate procedures such as affinity and size exclusion chromatography to improve resolution of 2-D gels. 

Kits and electrophoresis products are available to fractionate proteins based on their physical properties or cellular localization. Reducing sample complexity aids in the identification of low-abundance proteins.

Available kits use affinity chromatography techniques to deplete high-abundance proteins. Enrichment kits use a bead-based library of combinatorial peptide ligands to reduce levels of high-abundance proteins
