Storage & Solubility Information
| Bioactivity | Activity has not been tested. It is theoretically active, but we cannot guarantee it. |
| Description | B2M/beta 2-Microglobulin Protein, Human, Recombinant (His) is expressed in HEK293 Cells. The accession number is P61769-1. |
| Species | Human |
| Expression System | HEK293 Cells |
| Tag | C-His |
| Accession Number | P61769-1 |
| Construction | Ile21-Met119 |
| 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 0.22μm filtered solution in PBS (pH 7.4). Normally 8% trehalose is added as protectant 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 | β-2 microglobulin, beta-2 microglobulin |
| Research Background | The genetic and functional analysis of β2-microglobulin (B2M), a component of the HLA class-I complex.Acquired homozygous loss of B2M that caused lack of cell-surface HLA Class I expression in the tumor and a matched patient-derived xenograft (PDX). Downregulation of B2M was also found in two additional PDXs established from ICI-resistant tumors. |
| Molecular Weight | 12.8 kDa (Predicted); 13-15 kDa (Reducing conditions due to glycosylation) |
| Shipping | In general, lyophilized powders are shipped with blue ice, while solutions are shipped with dry ice. |
| Storage | It is recommended to store recombinant proteins at -20°C to -80°C for future use. 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. |
