Use BCA Protein Estimation Kit To Measure Protein

The bicinchoninic acid assay or BCA assay, also known as the Smith assay is a chemical assay for determining the overall concentration of protein like Lowry protein assay, Bradford protein assay or biuret reagent. The entire protein concentration is shown by a color change of the sample option from green to purple proportion to protein concentration.

A stock BCA alternative includes bicinchoninic acid, sodium carbonate, sodium bicarbonate, sodium tartrate, along with copper(II) sulfate pentahydrate. The BCA assay primarily depends upon two responses. The quantity of Cu2+ decreased is proportional to the quantity of protein within the solution.

Incubating the BCA assay at higher temperatures is advocated as a means to improve assay sensitivity while reducing the variances brought on by unequal amino acid makeup. The quantity of protein found in a solution can be measured by measuring the absorption spectra and comparing protein solutions of focus.

BCA Protein Assay Kit is a two-component, high-precision, detergent-compatible protein assay for determination of protein concentration. BCA reagents offer accurate determination of protein concentration with the majority of sample types encountered in protein study.

Even the BCA assay may be utilized to evaluate yields in whole cell lysates, affinity-column fractions, purified proteins samples, and to track protein contamination in industrial uses.  In comparison to the majority of dye-binding procedures, that the BCA assay is influenced less by protein compositional differences, providing higher concentration precision.

The BCA Protein Assay unites the renowned reduction of Cu2+ to Cu1+ by protein in an alkaline medium together with the highly sensitive and selective colorimetric detection of the cuprous cation (Cu1+) by bicinchoninic acid (BCA). The international peptide backbone also results in color formation, helping reduce variability brought on by protein compositional differences.
