Brief Introduction

Coomassie brilliant blue is proportional to protein concentration in a certain range, so it can be used for quantitative determination of protein. Coomassie brilliant blue is available in G-250 and R-250. Coomassie brilliant blue G-250 is red in free state and the maximum absorption is at 465 nm; When it combines with protein, it turns cyan, and the protein pigment conjugate has the maximum absorption at 595 nm. The light absorption is directly proportional to the protein content. The binding of protein with Coomassie brilliant blue G-250 reached equilibrium in about 2 minutes, and the reaction completed very quickly; The conjugates remained stable for 1 h at room temperature. The method was established by Bradford in 1976. The reagent preparation is simple and the reaction is very sensitive. The sensitivity is four times higher than that of Lowry method. It can be used to determine the protein content in microgram level, and the protein concentration range is 0 ~ 1000 μ G / ml, is a common method for rapid determination of trace protein.
