OVA peptide refers to specific fragments derived from ovalbumin, the primary protein found in egg whites. These peptides are of significant interest in immunology and allergy research due to their role as model antigens and their presentation by major histocompatibility complex (MHC) molecules.OVA Peptide (257-264)_索莱宝|主营生物科研试剂&抗体|蛋白 The most commonly studied OVA peptides are OVA (257-264) and OVA (323-339), each playing distinct roles in immune responses.

Ovalbumin itself is a well-characterized protein, making its derived peptides valuable tools for understanding cellular immunityOVA Peptide (257-264) - 金斯瑞生物科技有限公司. When ovalbumin is processed by immune cells, specific fragments, or epitopes, are presented on the cell surface by MHC molecules. These presented peptides are then recognized by T cells, initiating an immune response. The nature of this response, whether it leads to tolerance or an inflammatory reaction, is a key area of study.Thispeptideis derived fromovalbumin(OVA), a well-characterized protein, making it a valuable tool in immunological research, particularly for understanding ...

The Role of MHC and Specific OVA Epitopes

The presentation of OVA peptides to T cells is critically dependent on MHC molecules作者：NA Kukutsch·2000·被引用次数：93—We studied this issue by using the antibody 25-D1.16 that specifically detectsOVA peptide SIINFEKLin conjunction with H-2 K b molecules, and determined its kinetics.. For instance, the OVA (257-264) peptide, often referred to by its sequence SIINFEKL, is a classic example of a class I (Kb)-restricted peptide epitope of OVA. This means it is typically presented by the MHC class I molecule H-2Kb, primarily to CD8+ T cells. This interaction is fundamental in studying cytotoxic T lymphocyte (CTL) responses and is frequently used in experimental models to assess vaccine efficacy and immunotherapies.

In contrast, the OVA peptide (323-339) is recognized as a class II epitope, meaning it is presented by MHC class II molecules and interacts with CD4+ T cells.Peptide Institute, Inc. is aglobal supplier of OVA Peptide (257-264) from Japan.
