Kit supplied with the following:
By comparing a known amount of a 100% biotinylated AviTagTM fusion protein as a standard against a known amount of BirA-reacted protein-of-interest in an ELISA-type, multi-well dilution format (called BRTA for Biotinylation Reaction Titration Assay) it is possible to assess the extent of biotinylation achieved in your own BirA biotinylation reactions in a highly accurate and reproducible manner.
In addition, a mass shift between biotinylated and unbiotinylated fusion proteins visible on both SDS-PAGE and Western blot can be used to subjectively determine the amount of biotinylation that has occurred in a reaction by the observation of differences in band density in a mixed population of biotinylated vs. nonbiotinylated substrate.
The BIS-300 Kit contains the fully biotinylated standard used for the BRTA protocol and an unbiotinylated AviTag"d protein to react in a parallel to your BirA/protein biotinylation reaction as a positive control. A link to the BRTA protocol can be found here.

Avidity, LLC was founded in 1996 by Millard Cull, Larry Lansing, Dr. Ron Gill, and Dr. Mark Seville to develop peptide tags and molecular biology products based upon the extraordinary affinity of biotin for avidin or streptavidin. While working at Affymax as a researcher, Millard was involved in the discovery of the AviTag technology, saw its commercial potential, and obtained the exclusive rights from Affymax. He started Avidity as a reagent company that sublicenses the right to use the AviTag technology to other companies and sells products for use with the technology.
