In the field of cellular biology and immunological investigation, specific model antigens serve as the foundation for experimental design. Among these, the siinfekl peptide invivogen is widely recognized as a gold standard for researchers aiming to study MHC class I antigen presentation. As someone who has utilized various reagents in laboratory settings, I have found that the purity and consistenc Ovalbumin Epitope SIINFEKL Self-Assembles into a y of this specific ovalbumin-derived epitope are critical for obtaining reproducible results.
What is the SIINFEKL Peptide?
The OVA 257-264: SIINFEKL sequence is an immunodominant epitope derived from the chicken ovalbumin protein (Uniprot P01012). It is an octameric peptide that functions as a class I (Kb)-restricted epitope. In basic research, it is routinely used to stimulate ovalbumin-specific T cells, providing a reliable benchmark for studying how antigen-presenting cells (APCs) process and display foreign fragments.
