Application

Concentrated solution for all protein assays.
Protein standard has been used:

  • as a standard in the quantification of protein release by bicinchoninic acid assay[1]
  • as a standard in the quantification of urea by Bradfordassay[1]
  • as a molecular size marker for the quantification of protein by native polyacrylamide gel electrophoresis[2]
Protein standard for all protein assays. The sealed ampules provide assurance that the concentration will be correct with every assay.
This product is commonly used for protein determination by the Bicinchoninic Acid (BCA) method.

In biotechnological processes, technical failures in the upstream process often lead to batch loss. It is of great interest to investigate the empirical impact of technical failures to understand and mitigate their impact accurately and reduce economic damage. We investigated

Technical failures lead to deviations in process parameters that can exceed studied process boundaries. The impact on cell and target protein is often unknown. However, investigations on common technical failures might yield interesting insights into process and protein robustness. Recently

  4. Do you have any information on the traceability to a recognized protein standard, such as NIST? Or is the concentration derived from accepted values of natural physical constants?

    1 answer
    1. The concentration of each lot of the protein standard, Product P0914, is determined by UV measurements. Specifically, given a known extinction coefficient (E) and a measured absorbance (A), and assuming a standard pathlength of 1 cm, the concentration (c) can be determined by Beer's Law (c = A/E). The assay result is derived from an accepted value of a natural physical constant. Specifically, the E1% of 6.67 at approximately 279 nm is a well-accepted value, originally published in J. Am. Chem. Soc., 78, 3656-3660 (1956).
