Human WT-1 (HLA-A*02:01) Complex Tetramer Protein

Product Info

Recombinant Human WT-1 (HLA-A*02:01) Complex Tetramer Protein is expressed from Expi293 with His tag and Avi tag at the C-terminal,tetramer is assembled by biotinylated monomer and streptavidin. It contains Gly25-Thr305(HLA-A*02:01),Ile21-Met119(B2M) and RMFPNAPYL peptide.[Accession | P04439&P61769&RMFPNAPYL]

Molecular Weight

The protein has a predicted MW of 258 kDa. Due to glycosylation, the protein migrates to 260-265 kDa under Non reducing (N) condition based on Tris-Bis PAGE result.


Less than 1EU per μg by the LAL method.


> 95% as determined by Tris-Bis PAGE
> 95% as determined by SEC-HPLC


Supplied as 0.22μm filtered solution in PBS (pH 7.4).


The product should be stored at -70℃. Please do not repeated freeze-thaw cycles.

Assay Data
Tris-Bis PAGE

Human WT-1 (HLA-A*02:01) Complex Tetramer on Tris-Bis PAGE under reduced and non-reduced condition. The purity is greater than 95%.


The purity of Human WT-1 (HLA-A*02:01) Complex Tetramer was greater than 95% as determined by SEC-HPLC.


Immobilized Human WT-1 (HLA-A*02:01) Complex Tetramer at 1μg/ml (100μl/Well) on the plate. Dose response curve for Anti-WT-1 (HLA-A*02:01) Ab., hFc Tag with the EC50 of 10.0ng/ml determined by ELISA.

SPR Data

Anti-WT-1 (HLA-A*02:01) Antibody captured on Protein A chip, can bind Human WT-1 (HLA-A*02:01) Complex Tetramer, His Tag with an affinity constant of 0.18nM as determined in a SPR assay (Biacore T200).


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.
