In the specialized field of immunology and protein-based research, few tools are as fundamental as the OVA peptide (257-264). As a user who OVA 257-264is used to stimulate T cells in PBMCsand to quantify peptide epitope specificity and IFN-γ releasing effector cells by ELISPOT assay. OVA 257-264 Read more has navigated the technical landscape of laboratory-grade compounds, I have found that understanding the specific properties of this octameric sequence is essential for those involved in cellular studies.
Defining the Entity: What is OVA (257 OVA (257-264), scrambled | Bioactive Peptide -264)?
The OVA peptide (257-264), often referred to by its sequence SIINFEKL, is an immunodominant epitope derived from chicken ovalbumin protein. Ovalbumin (OVA) is the primary protein in egg-white, and it has long served as a model antigen for exploring biological pathways.
When we look at OVA (257-264), we are identifying a class I (Kb)-restricted pep This is aclass I (Kb)-restricted peptide epitope of OVA, an octameric peptide from ovalbumin presented by the class I MHC molecule, H-2Kb.Read more tide epitope of OVA. This means the peptide is specifically presented by the class I major histocompatibility complex (MHC) molecule, H-2Kb. In experimental setups, OVA 257-264 (SIINFEKL) acts as a precise tool for researchers who require a well-characterized antigen to study complex immune responses.
Practical Applications and Experimental Utility
My experience with this compound highlights its role as a gold standard in laboratory environments. It is frequently utilized in high-precision assays, such as those that measure levels or activity of cellular responses.
1. T-cell Stimulation: A primary use case for this molecule is that it is used to stimulate T cells in PBMCs. By introducing this ovalbumin-derived peptide, researchers can observe specific activation patterns.
2. Quantification: It is instrumental in quantifying peptide epitope specificity. Many laboratories use it in conjunction with ELISPOT assays to identify IFN-γ releasing effector cells.
3. Variant Studies: For those conducting comparative analysis, variants like the OVA-G4 peptide (SIIGFEKL) provide an interesting contrast to the native sequence, allowing for a deeper understanding of molecular binding affinities.
Quality and Technical Specifications
When sourcing research-grade Ova 257 264 peptide, purity is the most critical factor. I ha OVA (257-264), scrambledis a biological active peptide. (Out-of-order control peptide of HY-P1489). For research use only. We do not sell to patients.Read more ve found that high-quality synthesis—typically maintaining a purity level of >95% via HPLC—is necessary for reproducible data.
* Chemical Structure: The molecule, often provided as an OVA Peptide (257-264) TFA salt, has a molecular weight of approximately 963.2.
* Controls: In any rigorous study, the use of a scrambled version of the ovalbumin (OVA) peptide (257-264), known as FILKSINE, is vital. This control helps ensure that the observed OVA (257-264) Peptide Fragment effects are specific to the SIINFEKL sequence rather than the presence of the peptide itself.
Navigating Research Procurement
For those searching for high-purity OVA (257-264) peptide, it is important to distinguish between analytical reagents and other categories. While I have encountered questions regarding Ova peptide 257 264 dosage or potential applications, it is imperative to remember that these materials are strictly for *in vitro* research and laboratory experimentation. They are not intended for any other purpose.
Whether you are investigating the antigenic peptide properties or studying the H-2Kb class I MHC molecule, the OVA (257-264) peptide remains a cornerstone of modern molecular biology.
