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, 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/-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
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.

Description
The N-terminal 6xHis tag was fused to the gene fragment corresponding to the 715-953aa of the Mannheimia haemolytica lktA protein and then was cloned into an expression vector. The expression vector was transfected into the yeast cells for expression. The generated product was purified and separated to obtain the recombinant Mannheimia haemolytica lktA protein. Its purity is higher than 90%. This recombinant lktA protein showed an apparent molecular weight of about 30 kDa under SDS-PAGE condition.
The specified functions of lktA protein in diseases is not well understood. Some studies suggested that lktA production by Fusobacterium necrophorum strains in relation to severity of liver abscesses in cattle. Several researches suggested that lktA is related to the tumors. For example, it has been identified that lktA induces ATP expulsion through pannexin-1 channels and subsequent cell death in malignant lymphocytes.
