| Bioactivity | Immobilized Human HLA-A*02:01&B2M&MAGE-A4 (GVYDGREHTV) Tetramer, His Tag at 0.5μg/ml (100μl/Well) on the plate. Dose response curve for Anti-HLA-A*02:01&B2M&MAGE-A4 (GVYDGREHTV) Antibody, hFc Tag with the EC50 of 6.1ng/ml determined by ELISA (QC Test).Anti-HLA-A*02:01&B2M&MAGE-A4 (GVYDGREHTV) Antibody, hFc Tag captured on CM5 Chip via Protein A can bind Human HLA-A*02:01&B2M&MAGE-A4 (GVYDGREHTV) Tetramer, His Tag with an affinity constant of 8.49pM as determined in SPR assay (Biacore T200). |
| Description | Melanoma-associated antigen 4 is a protein that in humans is encoded by the MAGEA4 gene.The MAGE- A4 antigen is among the most commonly expressed cancer testis antigens. The Human HLA-A*0201 MAGE-A4 (GVYDGREHTV) complex Protein is a complex of HLA-A*0201 of the MHC Class I, B2M and GVYDGREHTV peptide of the MAGE-A4. |
| Species | Human |
| Expression System | HEK293 Cells |
| Tag | C-His-Avi |
| Accession Number | A0A140T913(HLA-A*02:01)&P61769(B2M)&GVYDGREHTV |
| Construction | Gly25-Thr305(HLA-A*02:01),Ile21-Met119(B2M) and GVYDGREHTV peptide. Tetramer is assembled by biotinylated monomer and streptavidin. |
| Protein Purity | > 95% as determined by Tris-Bis PAGE; > 95% as determined by HPLC |
| Endotoxin | < 1.0 EU/μg of the protein as determined by the LAL method. |
| Formulation | Lyophilized from a solution filtered through a 0.22 μm filter, containing PBS (pH 7.4). Typically, 8% trehalose is incorporated as a protective agent before lyophilization. |
| Reconstitution | Reconstitute the lyophilized protein in distilled water. The product concentration should not be less than 100 μg/ml. Before opening, centrifuge the tube to collect powder at the bottom. After adding the reconstitution buffer, avoid vortexing or pipetting for mixing. |
| Synonyms | MHC I, member 4, MAGE-X2, MAGE-A4, MAGE4B, MAGE4A, HLA0201, CT1.4 |
| Research Background | Melanoma-associated antigen 4 is a protein that in humans is encoded by the MAGEA4 gene.The MAGE- A4 antigen is among the most commonly expressed cancer testis antigens. The Human HLA-A*0201 MAGE-A4 (GVYDGREHTV) complex Protein is a complex of HLA-A*0201 of the MHC Class I, B2M and GVYDGREHTV peptide of the MAGE-A4. |
| 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. |
| Shipping | In general, lyophilized powders are shipped with blue ice, while solutions are shipped with dry ice. |
| Storage | Lyophilized powders can be stably stored for over 12 months, while liquid products can be stored for 6-12 months at -80°C. For reconstituted protein solutions, the solution can be stored at -20°C to -80°C for at least 3 months. Please avoid multiple freeze-thaw cycles and store products in aliquots. |
