The specific sequence known as peptide 257, more precisely identified as OVA peptide (257-264), is a crucial molecule in immunology. Derived from ovalbumin (OVA), this octameric peptide functions as a class I (Kb)-restricted peptide epitope.Description. Ovalbumin is the major protein in eggs.OVA [257-264] Peptideencompasses amino acids 257-264 of ovalbumin sequence, which is a class I ... Its significance lies in its ability to be presented by the MHC class I molecule, specifically H-2Kb, to T cells. This interaction is fundamental to initiating adaptive immune responses, making OVA peptide (257-264) a widely studied subject in research settings.
Ovalbumin, the primary protein found in egg white, serves as the source for this critical peptide fragment. The sequence of OVA peptide (257-264) is typically represented as SIINFEKLPeptide Institute, Inc. is a global supplier ofOVA Peptide (257-264) from Japan. Name:OVA Peptide (257-264), Code:4529-v, T-cell Activating Peptide.. As an immunodominant epitope, it is readily recognized by the immune system. Its presentation by MHC class I molecules, particularly the H-2Kb haplotype found in certain mouse strains, targets it for recognition by cytotoxic T lymphocytes (CTLs), also known as CD8+ T cells.Different Types of Peptides in Skincare & What They Do - Medik8 This characteristic makes it an invaluable tool for studying T-cell mediated immunity and developing immunotherapies.
The well-defined nature of OVA peptide (257-264) and its role in immune responses have led to its extensive use in various research applications.Peptide Institute, Inc. is a global supplier ofOVA Peptide (257-264) from Japan. Name:OVA Peptide (257-264), Code:4529-v, T-cell Activating Peptide. It is frequently employed as a model antigen to stimulate and investigate T-cell activation, proliferation, and effector functions. Researchers utilize it to test the efficacy of new adjuvants and to develop experimental vaccines. For instance, its ability to form stable hydrogels and elicit a robust immune response has been explored in the context of immunotherapeutic vaccine development. The peptide's predictable interaction with H-2Kb allows for controlled experiments to dissect complex immunological pathways.
While the term "peptide 257" might broadly refer to various peptide sequences, in the context of immunological research, it almost invariably points to the ovalbumin-derived SIINFEKL sequenceOva peptide (257-264) | C45H74N10O13 | CID 22134157 - structure, chemical names, physical and chemical properties, classification, patents, literature, .... Its specific presentation by MHC class I H-2Kb is a defining characteristic.OVA Peptide(257-264) is a class I (Kb)-restricted peptide epitope of OVA, an octameric peptide can be from ovalbumin presented by the class I MHC molecule, H- ... This specificity differentiates it from other peptide epitopes that might be presented by different MHC molecules or derived from different proteins. For example, while other peptides can stimulate immune responses, OVA peptide (257-264) serves as a standard for evaluating antigen presentation and T-cell responses in specific genetic backgrounds, particularly in C57BL/6 mice, which are H-2b haplotype.
Research-grade Ova 257 264 Peptide is commercially available from various suppliers, often in its trifluoroacetate (TFA) salt form, which enhances stability and solubility. When procuring this peptide, purity is a key consideration, with high-performance liquid chromatography (HPLC) often used to ensure purity levels exceeding 95%.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， ...
