In the specialized field of biochemical research, selecting the correct OVA peptide sequence catalog peptides is a foundational step for any laboratory workflow. My personal experience working with these reagents has highlighted the importance of sourcing high-purity materials, especially when dealing with model antigens derived from chicken ovalbumin protein (UniProt ID: P01012). Understanding the nuances of these sequences is essential for maintaining consistency in experimental design.
Understanding the Primary OVA Peptide Sequences
When exploring a catalog peptide, researchers typically focus on two standard OVA peptides for detection use: the class I and class II epitopes. These are indispensable in immunological studies, particularly when looking at how ova fragments interact with specific receptors.
The Class I Epitope: OVA (257-264)
The OVA peptide (257-264), widely known by its one-letter sequence SIINFEKL, is a H-2Kb-restricted octameric peptide. Its molecular formula is C45H74N10O, with a molecular weight of 963.13. In my experience, this is considered the gold standard for CD8+ T cell assays.

The Class II Epitope: OVA (323-339)
The OVA (323-339) peptide sequence is H - Ile - Ser - Gln - Ala - Val - His - Ala - Ala - His - Ala - Glu - Ile - Asn - Glu - Ala - Gly - Arg – OH. This ISQAVHAAHAEINEAGR sequence is a prominent antigen peptide derived from ovalbumin. It functions as a critical tool in allergy research and studies concerning major histocompatibility complex (MHC) binding. Because OVA peptide mainly exists in egg white, this synthetic version allows for precise control over concentration and binding registers, such as the I-A(d)-restricted epitope.
Navigating the Catalog: What to Look For
When you are searching for OVA (ovalbumin) peptide, you will encounter various modifications. Top-tier providers offer ovalbumin peptides labeled with biotin, TAMRA, FITC, or FAM. These labels are vital for visualization in sensitive assays.
* Purity: Always look for >95% purity to avoid interference from truncated sequences.
* Documentation: A reliable catalog peptide provider should always supply the This is a class I (Kb)-restrictedpeptideepitope ofOVA, an octamericpeptidefromovalbuminpresented by the class I MHC molecule, H-2Kb. amino acid sequence and mass spectrometry data to verify the ISQAVHAAHAEINEAGR identity.
* Application: Whether you are utilizing OVA (257-264) for OVA (ovalbumin) model research or investigating the OVA protein structure, specificity is key.
Integrating OVA Peptides into Research
The versatility of these sequences is remarkable. For instance, OVA (ovalbumin) peptide residues 257 to 280—often referred to as the OT-II peptide—is frequently used to study helper CD4+ T cell responses. When I have used high-purity OVA (257-264) peptide in my own setups, the reproducibility of the data was significantly higher compared to lower-grade alternatives.
