Recombinant Human HLA class I histocompatibility antigen,A-1 alpha chain(HLA-A),partial

Product Details

Description

The recombinant human HLA-A is generated by expressing the target gene fragment in E.coli and fusing the 6xHis motif to the N-terminus of the resulting protein. The target gene region maps within amino acids 25-308 (extracellular domain) of the HLA-A protein. Its purity is greater than 85% measured by SDS-PAGE. It migrated to the molecular weight band of 36-40 kDa on the gel. This 6xHis-tagged recombinant HLA-A protein has also been validated its component by the LC-MS/MS analysis. It is in stock now. The target protein HLA-A is the α chain of the HLA class I molecule, which is located in the endoplasmic reticulum (ER) with peptide fragments derived from proteolytically degraded proteins. These HLA class I/peptide complexes are then surface-expressed and presented to CD8+ T cells.

Purity Greater than 85% as determined by SDS-PAGE.

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.
Note: If you have any special requirement for the glycerol content, please remark when you place the order.
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 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 Basically, we can dispatch the products out in 3-7 working days after receiving your orders. Delivery time may differ from different purchasing way or location, please kindly consult your local distributors for specific delivery time.
Notes Repeated freezing and thawing is not recommended. Store working aliquots at 4°C for up to one week.
