KRAS Q61H Protein, Human, Recombinant, AviTag
Recombinant KRAS Q61H protein with the N-terminal AviTag™ peptide and His-tag is produced in E. coli cells. Presence of AviTag™ peptide can be useful for a site-specific biotinylation with BirA enzyme (https://amidbiosciences.com/collections/biotinylation-tools-streptavidins/products/bira-biotin-ligase-in-vitro-biotynilation).
