PE-Labeled Mouse H-2Kb&B2M&OVA (SIINFEKL) Tetramer Protein
表达区间及表达系统(Source)
PE-Labeled Mouse H-2Kb&B2M&OVA (SIINFEKL) Tetramer Protein (H2A-MP2H7) is expressed from human 293 cells (HEK293). It contains AA Gly 22 - Thr 305 (H-2Kb) & Ile 21 - Met 119 (B2M) & SIINFEKL peptide (Accession # P01901 (H-2Kb) & P01887 (B2M) & SIINFEKL).
Predicted N-terminus: Gly 22 & Ile 21
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)
卵清蛋白(OVA)可以基于特征明确的肽表位诱导体液和细胞免疫反应。OVA257-264八肽是首批被鉴定的OVA表位之一,其氨基酸序列为SIINFEKL,可被细胞毒性T淋巴细胞识别。如果卵清蛋白(Ova)通过皮诺体的渗透裂解从皮诺体释放到细胞质中,则会被呈递给T细胞。佐剂SIINFEKL肽免疫诱导小鼠长期CD8+T细胞免疫。
