Biotinylated Mouse I-Ab&OVA 323-339 (ISQAVHAAHAEINEAGR) Monomer Protein (MHC-MM4I1B) Summary

Product Description

Recombinant Biotinylated Mouse I-Ab&OVA 323-339 (ISQAVHAAHAEINEAGR) Monomer Protein is expressed from HEK293 with His tag and Avi tag at the C-terminus.It contains Ile27-Glu218 (H2-Aa), Ser30-Lys226 (H2-Ab1) and ISQAVHAAHAEINEAGR peptide.

Product Background

OVA 323–339 (ISQAVHAAHAEINEAGR) is a 17–amino acid peptide from chicken Ovalbumin. It is a well-known CD4⁺ T-cell epitope presented by MHC class II molecules to activate helper T cells. This peptide is widely used in mice to study antigen-specific T-cell responses and immune regulation, including models of allergy and autoimmunity. Its defined sequence and reproducible immunogenicity make it a common tool in immunology research.
