Tag Info

N-terminal GST-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. 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 preparation of the recombinant Streptococcus gordonii gspB protein involves manipulating the expression of the desired gene in e.coli cells. The sequence (233-617aa) of foreign DNA is fused to an expression vector and then introduced into e.coli cells. Selected positive cells are cultured to induce the expression of the desired protein. The protein features a N-terminal GST tag fusion. The recombinant targeted protein is subjected to affinity purification. Its purity exceeds 90% as assessed by SDS-PAGE.

Target Background

Function

Plays a role in virulence and host-pathogen interactions. Mediates binding to human platelets via interaction with the human cell surface glycoprotein GP1BA. Plays a positive role in biofilm formation, possibly by self-association via the basic region (BR).

Subcellular Location

Secreted, cell wall; Peptidoglycan-anchor.

Protein Families

SraP family
