Form
Liquid or Lyophilized powder
Note: We will preferentially ship the format that
we have in stock, however, if you have any special requirement for the format, please remark your
requirement when placing the order, we will prepare according to your demand.
Buffer
If the delivery form is liquid, the default storage buffer is Tris/PBS-based buffer, 5%-50% glycerol.
If the delivery form is lyophilized powder, the buffer before lyophilization is Tris/PBS-based buffer, 6% Trehalose, pH 8.0.
Reconstitution
We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Please reconstitute protein in deionized sterile water to a concentration of 0.1-1.0 mg/mL.We recommend to add 5-50% of glycerol (final concentration) and aliquot for long-term storage at -20°C/-80°C. Our default final concentration of glycerol is 50%. Customers could use it as reference.
Storage Condition
Store at -20°C/-80°C upon receipt, aliquoting is necessary for mutiple use. Avoid repeated freeze-thaw
cycles.
Shelf Life
The shelf life is related to many factors, storage state, buffer ingredients, storage temperature
and the stability of the protein itself.
Generally, the shelf life of liquid form is 6 months at -20°C/-80°C. The shelf life of lyophilized
form is 12 months at -20°C/-80°C.
Lead Time
3-7 business days
Notes
Repeated freezing and thawing is not recommended. Store working aliquots at 4°C for up to one week.

Description
Investigate the complexities of the human immune system with our Recombinant Human HLA-DRB1 protein, a critical component of the HLA class II histocompatibility antigen family. This essential protein is involved in antigen presentation to CD4+ T-lymphocytes, playing a significant role in the adaptive immune response and contributing to the development of various immune-related disorders.
Sourced from E. coli expression systems, our Recombinant Human HLA-DRB1 encompasses a partial sequence (31-266 amino acids) and features an N-terminal 6xHis-tag for efficient purification and detection. With a purity greater than 90% as determined by SDS-PAGE, this high-quality protein ensures reliability and consistency in your research. Available in both liquid and lyophilized powder forms, our Recombinant Human HLA-DRB1 caters to your specific experimental needs.
