BCA Protein Quantification Kit

This BCA protein quantification kit is designed based on a specific reaction principle and is used for precisely determining the protein content in the test sample.
The core principle is that protein molecules can convert Cu in an alkaline solution^{2 +}Restore to Cu⁺And 2,2 '-biquinoline-4,4' -dicarboxylic acid (BCA) can react with Cu⁺Specific binding, forming a stable purple complex; Within a certain concentration range, the depth of the color of this complex is in a good direct proportion to the protein concentration.
This kit plots a standard curve through protein standard solution and can quickly and accurately determine the protein content in the test sample by colorimetry. This product has stable and reliable performance. Among them, the linear fitting equation R² of the standard product is ≥0.99, ensuring a good linear relationship. In terms of precision, the relative standard deviation (RSD%) of the duplicate Wells of the standard sample and the test sample is ≤10%, and the repeatability is excellent. In terms of accuracy, the detection error of the enterprise's self-made internal control products is ≤10%, which can effectively ensure the accuracy of the test results and provide reliable support for protein quantitative analysis.

1. The linear relationship of the standard product is stable, and it linearly fits R²≥0.99。

2. High precision: The RSD% of the duplicate Wells for standard and test samples is ≤10%.

3. High accuracy: The detection error of the enterprise's self-made internal control products is ≤10%.
