[交流] 请问Bio-rad protein assay 什么意思?

我是学分析的,对一些生物的东西不够了解,看文献中有“Bio-rad protein assay(Bio-rad Laboratories, Hercules, CA)”,是什么意思?应该是一种定量测定蛋白含量的方法吧?
整个句子是这样的“the protein content of the combined supernatant was measured using a Bio-rad protein assay (Bio-rad Laboratories, Hercules, CA) with bovine serum albumin as a protein standard.”

Bio-Rad Protein Assay

Introduction

The Bio-Rad Protein Assay, based on the method of Bradford, is a simple and accurate procedure for determining concentration of solubilized protein. It involves the addition of an acidic dye to protein solution,and subsequent measurement at 595 nm with a spectrophotometer or microplate reader. Comparison to a standard curve provides a relative measurement of protein concentration.

可能有些乱,另:

The absorbance maximum for an acidic solution of
Coomassie® Brilliant Blue G-250 dye shifts from 465 nm to 595 nm when
binding to protein occurs

Bio-Rad是一家生物公司的名字
这里的Bio-Rad protein assay dye应该是一种Bio-Rad的用以蛋白质定量的染色试剂
