Product introduction

Recombinant Human HLA-A*02:03&B2M&AFP (FMNKFIYEI) Tetramer Protein is expressed from HEK293 His tag and Avi tag at the C-terminus, tetramer is assembled by biotinylated monomer and streptavidin. It contains Gly25-Thr305(HLA-A*02:03), Ile21-Met119(B2M) and FMNKFIYEI peptide (accession: AAA03604.1(HLA-A*02:03) & P61769(B2M) &FMNKFIYEI).

Product details

Molecular aliases: Alpha-fetoprotein; Alpha-1-fetoprotein; Alpha-feto; AFP; HPAFP; AFPD; FETA; MHC
Protein length: Gly25-Thr305
Expression system: HEK293
Molecular weight: The protein has a predicted MW of 258 kDa. Due to glycosylation, the protein migrates to 260-265 kDa under Non reduced (N) condition based on Bis-Tris PAGE result.
Purity: > 95% as determined by Bis-Tris PAGE > 95% as determined by HPLC
Endotoxin: Less than 1 EU per μg by the LAL method.
Formulation: Lyophilized from 0.22μm filtered solution in PBS (pH 7.4). Normally 8% trehalose is added as protectant before lyophilization.
State: Lyophilized
Storage: -20 to -80°C for 12 months as supplied from date of receipt. -80°C for 3 months after reconstitution. Recommend to aliquot the protein into smaller quantities for optimal storage. Please minimize freeze-thaw cycles.
Reconstitution: Dissolve the lyophilized protein in distilled water. Please refer to the Certificate of Analysis for detailed instructions.

SEC-HPLC Data — The purity of Human HLA-A*02:03&B2M&AFP (FMNKFIYEI) Tetramer is greater than 95% as determined by SEC-HPLC.

Background

Alpha-fetoprotein (AFP), a specific liver cancer marker, T cells expressing AFP-CAR selectively degranulated, released cytokines, and lysed liver cancer cells that were HLA-A*02:01 /AFP while sparing cells from multiple tissue types that were negative for either expressed proteins.CAR T-cell immunotherapy targeting intracellular/secreted solid tumor antigens can elicit a potent antitumor response.
