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.
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.
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.
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.

The fusion tag N-terminal 6xHis tag gene was added to the gene sequence corresponding to the yeast of the HHV-1 US12 protein to form the recombinant DNA. The recombinant DNA was cloned into the expression vector and then transfected into the yeast cells for expression. Following purification, the product is the recombinant HHV-1 US12 protein carrying N-terminal 6xHis tag. The SDS-PAGE assessed the purity of this recombinant US12 protein up to 90%. It had an apparent molecular weight of approximately 14 kDa.
US12 is gene providing instructions for making a protein named human herpesvirus 1 ICP47 protein (abbreviated US12) and belongs to Herpesviridae US12 family. US12, a HSV immediate early protein, is small protein produced by the herpes simplex virus, is considered as an important factor in the evasion of cellular immune responses in HSV-infected cells. It is expressed very early after infection and can inhibit CD8+ T cell recognition of infected cells. Recent studies have established clearly that ICP47 can bind with high affinity to human TAP and inhibit the transport of peptides into the endoplasmic reticulum.
