Target Protein Sequence
Note: The complete sequence including tag
sequence, target protein sequence and linker sequence could be provided upon request.
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.
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.
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℃/-80℃. Our default final concentration of glycerol is 50%. Customers could use it as reference.
Store at -20°C/-80°C upon receipt, aliquoting is necessary for mutiple use. Avoid repeated freeze-thaw
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.
Delivery time may differ from different purchasing way or location, please kindly consult your local distributors for specific delivery time.
Repeated freezing and thawing is not recommended. Store working aliquots at 4°C for up to one week.

To generate the biotinylated recombinant human tyrosine-protein phosphatase non-receptor type substrate 1 (SIRPA) in mammalian cells, first, construct an expression vector containing the target gene fused with a 6xHis-Avi-tag sequence at the C-terminus. The target gene encodes the amino acids 31-370 of the human SIRPA protein. And then, transfect the recombinant vector into mammalian cells using appropriate methods. Culture the transfected cells and induce expression of the recombinant SIRPA protein. Introduce a biotin ligase enzyme or co-express it with the recombinant protein to attach biotin molecules to the 6xHis-Avi-tag sequence. Harvest the cells or collect the culture supernatant and purify the biotinylated recombinant SIRPA protein. The purity of the biotinylated recombinant human SIRPA protein is over 90%.
