peptide 257 257 - Cell peptides OVA Peptide(257-264) TFA Understanding Peptide 257: A Deep Dive into the OVA (257-264) Epitope

Peptideshop online The term "peptide 257" often leads researchers and scientists to a specific and highly studied molecule: the OVA Peptide (257-264). This peptide is a crucial component in immunological research, particularly in understanding T-cell responses and vaccine development. Its significance lies in its role as a class I (Kb)-restricted peptide epitope of OVA, a fragment derived from ovalbumin, the major protein found in egg whites. This article will delve into the intricacies of peptide 257, exploring its structure, function, and applications, drawing upon information from scientific literature and commercial suppliers.

At its core, peptide 257 refers to a specific sequence of amino acids within the ovalbumin protein.OVA Peptide (257-264）（CAS号1262751-08-5），肽序列Ser-Ile-Ile-Asn-Phe-Glu-Lys-Leu，是鸡卵清蛋白（OVA）的核心抗原表位，兼具抗原特异性免疫激活与免疫耐受调控双重活性， ... This particular segment, spanning from amino acid 257 to 264, is known by its sequence SIINFEKL. It is an octameric peptide, meaning it is composed of eight amino acids linked together by peptide bonds. The precise sequence and its presentation by the immune system make it a valuable tool for studying immune responses.

The primary function and significance of OVA Peptide (257-264) stem from its interaction with the immune system's major histocompatibility complex (MHC) molecules.Ova peptide (257-264) | C45H74N10O13 - PubChem - NIH Specifically, it is recognized as a class I (Kb)-restricted peptide epitope. This means that it is presented by the Class I MHC molecule, H-2Kb, on the surface of cells. This presentation is a critical step in the adaptive immune response, signaling to cytotoxic T lymphocytes (CTLs), also known as CD8+ T cells, that the cell is either infected or abnormal. The stimulation of these CD8+ cells and their cytotoxic T lymphocyte response is a key area of investigation when using this peptide.

The availability of peptide 257 is widespread through various scientific suppliers. Companies offer Research-grade Ova 257 264 Peptide for laboratory use, often specifying purity levels and forms such as OVA Peptide(257-264) TFAOVA 257-264 (SIINFEKL) is a well-characterized, immunodominant epitope derived from chicken ovalbumin protein (Uniprot P01012).. The "TFA" in the name refers to trifluoroacetic acid, a common counterion used during peptide synthesis and purification, ensuring stability and purity. These suppliers provide detailed information, including CAS numbers (e.g.OVA Peptide 257-264 2TFA. 别名: (2S,5S,8S,11S,14S,17S,20S,23S)-23-amino-14-(2-amino-2-oxoethyl)-5-(4-aminobutyl)-11-benzyl-17,20-di((S)-sec-butyl)-8-(2 ..., CAS NOOVA 257-264 scrambled (FILKSINE). 1262751-08-5), chemical structures, and molecular formulas (e.g., C45H74N10O13 as listed for Ova peptide (257-264) on PubChem).

Beyond its direct use in immune stimulation, the OVA Peptide (257-264) is also studied for its structural properties. It can form a stable hydrogel, and its linear structure, formed by the linkage of eight amino acids via peptide bonds, contributes to its specific binding to MHC molecules. The precise spatial arrangement of the amino acids in the OVA [257-264] Peptide allows for specific binding to the H-2Kb molecule, a characteristic that can be further probed using specific antibodies like the 25-D1.16 monoclonal antibody, which reacts with the ovalbumin-derived peptide SIINFEKL bound to H-2Kb.
