蛋白结构(Molecular Characterization)
PE-Labeled Mouse H-2Kb&B2M&OVA (SIINFEKL) Tetramer Protein is assembled by biotinylated monomer (H2A-M82E6) and PE-labeled streptavidin.
Biotinylated Mouse H-2Kb&B2M&OVA (SIINFEKL) Complex Protein is produced by co-expression of H-2Kb and B2M loaded with OVA peptide. Biotinylated Mouse H-2Kb&B2M&OVA (SIINFEKL) Complex Protein carries a polyhistidine tag at the C-terminus, followed by an Avi tag (Avitag™).

背景(Background)
Ovalbumin (OVA) can induce both humoral and cellular immune responses based on well-characterized peptide epitopes. The OVA257-264 octapeptide was one of the first OVA epitopes to be characterized, it has an amino acid sequence SIINFEKL, which is recognized by cytotoxic T lymphocytes. ovalbumin (Ova) was presented to T cells if it was released from pinosomes into the cytosol by osmotic lysis of pinosomes. Immunization with the adjuvanted SIINFEKL peptide induces long-lasting CD8+ T cell immunity in mice.
