Product Catalog

BirA biotin-protein ligase kits for rapid and efficient biotinylation of purified proteins or peptides that have a biotin-acceptor peptide sequence such as our patented AviTag^TM.

High efficiency biotinylation strains featuring a BirA-overproducing gene either in plasmid form or chromosomally integrated for use with our pAN or pAC vectors or consumer-produced plasmid vectors.

The Expresso® Biotin Cloning & Expression System

We offer an antibody that will recognize the AviTag and enable you to purify your AviTag'd protein.

Avidity provides purified proteins that have either a biotinylated AviTag or a linked to Streptavidin for Biotin interaction. Our protein portfolio contains Luciferases and Fluorescent Proteins that can for example be used for Streptavidin-Biotin quantification.

Avidity is providing vectors for cloning and expression of N-terminal (pANs) or C-terminal (pACs) AviTagTM.
