Benzathine Benzylpenicillin CAS 41372-02-5

Description:

Coomassie brilliant blue is directly proportional to protein concentration in a certain range, so it can be

used for quantitative determination of protein. There are two kinds of Coomassie Brilliant Blue: G-250

and R-250. Coomassie brilliant blue G-250 is red in the free state, with the maximum light absorption at

465nm; when it combines with protein, it becomes blue, and the protein pigment combination has the

maximum light absorption at 595nm. Its light absorption value is directly proportional to protein content.

The binding of protein and Coomassie brilliant blue G-250 reached equilibrium in about 2 minutes, and the

reaction was very rapid; the binding of protein and Coomassie brilliant blue G-250 remained stable in 1 hour

at room temperature. This method was established by Bradford in 1976. The reagent is simple to prepare, easy

to operate, and very sensitive. Its sensitivity is 4 times higher than Lowry method. It can be used to determine

the content of microgram protein. The range of protein concentration is 0-1000 μ g / ml. it is a commonly

used method for rapid determination of trace protein
