BCA Protein Assay Kit

Chemical Properties

Fully miscible in water.


BCA Protein Assay Kit can be used to measure very dilute protein concentrations in very small sample volumes. Accurately measures protein concentrations from 0.5 to 30 ?g/mL in tube assays and 1 to 20 ?g/mL in 96- or 384-well plate assays. It is used for studying protein: protein interactions, measuring column fractions after affinity chromatography, estimating percent recovery of membrane proteins from cell extracts and high-throughput screening of fusion proteins.


Contains 250ml of solution A and 5.5ml of solution B. Solution A: Bicinchonic acid and tartrate in an alkaline carbonate buffer; Solution B: 4% w/v cupric sulfate
