OVA (323-339) Chicken Ovalbumin Peptide (ISQAVHAAHAEINEAGR)

The OVA 323-339 peptide (sequence: ISQAVHAAHAEINEAGR) is a prominent antigen peptide derived from chicken ovalbumin protein (UniProt ID: P01012). This peptide represents an immunodominant epitope and serves as a major MHC class II-restricted T-cell epitope of ovalbumin, binding specifically to H2-IAd. Furthermore, OVA 323-339 functions as a B-cell epitope, recognized by IgE antibodies, making it highly relevant in allergy research and immunology. As a principal immunogenic component of ovalbumin, OVA 323-339 is known for eliciting responses in cases of egg allergies.

The Chicken Ovalbumin Peptide is a high quality epitope peptide for stimulation of antigen-specific T cells in T cell assays such as ELISPOT, ICS, cytotoxicity or proliferation assays. The Ovalbumin Peptide, H-ISQAVHAAHAEINEAGR-OH (Uniprot: P01012 aa: 323 - 339) from JPT is produced under strict quality control and quality management.
