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.Description. Ovalbumin is the major protein in eggs.OVA [257-264] Peptideencompasses amino acids 257-264 of ovalbumin sequence, which is a class I ... 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 immunity. 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 responseOVA peptideis a class I (Kb)-restricted peptide epitope of ovalbumin presented by the class I MHC (major histocompatibility complex) molecule, H-2Kb.. The nature of this response, whether it leads to tolerance or an inflammatory reaction, is a key area of study.
The presentation of OVA peptides to T cells is critically dependent on MHC molecules. 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.Two standard OVA peptides for detection use: H-2Kb-restricted OVA class I epitope and an I-A(d)-restricted OVA class II epitope. Endotoxin-free. 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 immunotherapiesAs a model antigen in eliciting immune response, our diverse offering of ovalbumin peptides includingOVA (257-264) continue to help in immuneprofiling ....
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.2021年11月11日—This is aclass I (Kb)-restricted peptide epitope of OVA, an octameric peptide from ovalbumin presented by the class I MHC molecule, H-2Kb. These CD4+ T cells are crucial for orchestrating broader immune responses, including the activation of B cells that produce antibodies and the regulation of other immune cell types. Understanding the differences in presentation and T cell recognition between these two prominent OVA peptides is vital for dissecting complex immune mechanismsOvalbumin(323-339) peptide binds to the major ... - PubMed.
Due to its abundance in egg whites and its well-defined immunological properties, ovalbumin and its constituent peptides have become standard model antigens in immunological researchThis is aclass I (Kb)-restricted peptide epitope of OVA, an octameric peptide from ovalbumin presented by the class I MHC molecule, H-2Kb.. Researchers utilize OVA peptides to:
* Induce and study allergic responses: The role of ovalbumin as a common allergen makes OVA peptides essential for investigating the mechanisms behind immediate hypersensitivity reactions and developing diagnostic or therapeutic strategies for food allergies.The OVA 323-339 peptide (sequence: ISQAVHAAHAEINEAGR) isa prominent antigen peptide derived from chicken ovalbumin protein(UniProt ID: P01012).
* Evaluate vaccine efficacy: OVA peptides, particularly SIINFEKL, are frequently employed in preclinical studies to test new vaccine adjuvants and delivery systems.OVA (257-264) Peptide Fragment By observing the immune response to these well-defined epitopes, researchers can gauge the potency and specificity of experimental vaccines.
* Investigate T cell activation and function: Specific OVA peptides can be used *in vitro* to stimulate or expand T cell populations, allowing for detailed analysis of T cell receptor interactions, cytokine production, and effector functions.
* Develop immunological assays: OVA peptides serve as reliable targets for various immunological assays, including ELISpot, flow cytometry, and MHC stabilization assays, aiding in the characterization of immune responses.
The availability of high-purity OVA peptides from various suppliers has facilitated their widespread use in laboratories worldwide. These peptides allow for precise control over experimental conditions, enabling a deeper understanding of immune system dynamicsOva-Peptide Conjugation Kit.
OVA peptides, originating from the common egg white protein ovalbumin, are indispensable tools in modern immunology. Specifically, the class I-restricted OVA (257-264) and the class II-restricted OVA (323-339) peptides are critical for studying T cell recognition, orchestrating immune responses, and investigating mechanisms of allergy and vaccine development. Their well-defined nature and consistent behavior as model antigens continue to drive significant advancements in our understanding of the immune system.
