Bicinchoninic acid bca protein assay kit

Manufactured by Applygen
Sourced in China

The Bicinchoninic acid (BCA) protein assay kit is a colorimetric detection and quantification method for determining the total protein concentration in a sample. The kit utilizes the bicinchoninic acid reaction to produce a purple-colored complex, which can be measured spectrophotometrically. The intensity of the color is proportional to the protein concentration in the sample.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
