| 确定序列 | Ile21-Met119 |
| 分子量 | The recombinant Human B2M/beta 2-Microglobulin protein with the His tag at the C-terminus has a predicted MW of 12.8 kDa. Due to glycosylation, the protein migrates to 13-15 kDa based on Tris-Bis PAGE result. |
| Form | Lyophilized |
| 形式 | Lyophilized from 0.22 um filtered solution in PBS (pH 7.4). Normally 8% trehalose is added as protectant before lyophilization. |
| 制剂 | It is recommended to reconstitute the lyophilized recombinant Human B2M/beta 2-Microglobulin Protein in sterile H2O to a protein concentration not less than 100 ug/ml. Centrifuge the tube before opening. |
| 纯度 | >95% by SEC-HPLC and SDS-PAGE under reducing conditions. |
| 内毒素 | Less than 1 EU per ug of protein as determined by LAL method. |
| 运输 | The recombinant Human B2M/beta 2-Microglobulin Protein is shipped with ice pack. Upon receipt, store it immediately at the temperature recommended below. |
| 稳定性与储存 | '-20 to -80°C for 12 months as supplied from date of receipt.； -20 to -80°C for 3-6 months in unopened state 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. |
| 注意事项 | Conditions of optimal recombinant Human B2M/beta 2-Microglobulin Protein performance should be determined experimentally by the investigator. |

BP005118: Human B2M/beta 2-Microglobulin Protein with the C-His Tag (人 B2M/β 2-微球蛋白 C-His 标签)
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.
