Recombinant Chimeric HLA-A*02:01(ma3)&B2M&WT-1 (RMFPNAPYL) Tetramer Protein is expressed from HEK293 with His tag and Avi tag at the C-Terminus, tetramer is assembled by biotinylated monomer and streptavidin.It contains Gly25-Thr206(Human HLA-A*02:01 a1&a2)&Asp207-Glu299(Mouse H-2Ld a3), Ile21-Met119 (B2M) and RMFPNAPYL peptide. The WT1 protein plays a role in cell growth, the process by which cells mature to perform specific functions (differentiation), and the self-destruction of cells (apoptosis). WT1 is differentially expressed in serous, endometrioid, clear cell, and mucinous carcinomas of the peritoneum, fallopian tube, ovary, and endometrium.The Human HLA-A*0201 WT-1 (RMFPNAPYL) complex Protein is a complex of HLA-A*0201 of the MHC Class I, B2M and RMFPNAPYL peptide of the WT-1.
