Name : Human HLA-A*02:01&B2M&AFP (PLFQVPEPV) Tetramer Protein
Product Source :
Recombinant Human HLA-A*02:01&B2M&AFP (PLFQVPEPV) 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-Thr305(HLA-A*02:01),Ile21-Met119(B2M) and PLFQVPEPV peptide.[Accession | A0A140T913(HLA-A*02:01)&P61769(B2M)&PLFQVPEPV]
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.
Endotoxin Level :
Less than 1EU per ug by the LAL method.
Purity :
> 95% as determined by Tris-Bis PAGE> 95% as determined by HPLC
Formulation :
Lyophilized from 0.22μm filtered solution in PBS (pH 7.4). Normally 8% trehalose is added as protectant before lyophilization.
Reconstitution :
Centrifuge the tube before opening. Reconstituting to a concentration more than 100 μg/ml is recommended. Dissolve the lyophilized protein in distilled water.
Storage and Stability :
-20 to -80°C for 12 months as supplied from date of receipt. -80°C for 3-6 months after reconstitution. 2-8°C for 2-7 days after reconstitution. Recommend to aliquot the protein into smaller quantities for optimal storage. Please minimize freeze-thaw cycles.
Product Concentration :
Tris-Bis PAGE Human HLA-A*02:01&B2M&AFP (PLFQVPEPV) Tetramer on Tris-Bis PAGE under Non reducing (N) condition. The purity is greater than 95%. SEC-HPLC The purity of Human HLA-A*02:01&B2M&AFP (PLFQVPEPV) 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.
Synonyms :
Alpha-fetoprotein; Alpha-1-fetoprotein; Alpha-feto; AFP; HPAFP; AFPD; FETA; MHC
