Tag Info

N-terminal 6xHis-tagged

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.

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.

Troubleshooting and FAQs

Protein FAQs

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

The first step in producing the recombinant Salmonella typhi uspA protein is to construct a plasmid that encodes the Salmonella typhi uspA protein (2-144aa). The next is to transform this plasmid into e.coli cells, select positive e.coli cells, from which positive cells can be screened and cultured to express the protein. A N-terminal 6xHis tag is fused to the protein. The recombinant Salmonella typhi uspA protein is purified through affinity purification from the cell lysate. Its purity is greater than 90%, determined by the SDS-PAGE analysis.
