Protein Length
Full Length of Mature Protein
Tag Info
N-terminal 6xHis-SUMO-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
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 expression of recombinant human ASPN protein includes the construction of the expression vector containing the recombinant DNA and the transformation of the expression vector into the E.coli, which provides a variety of macromolecules and components required for transcription and translation. The recombinant DNA was formed by fusing the N-terminal 6xHis-SUMO tag sequence to the designated sequence encoding the 33-380aa of the human ASPN protein. This N-terminal 6xHis-SUMO-tagged recombinant human ASPN protein is also characterized by high purity, >90%. Under SDS-PAGE condition, this recombinant ASPN protein migrated to the band of about 55 kDa molecular weight.
It is well-documented that ASPN was upregulated in different stages of gastric cancer (GC),and associated with a poor prognosis and could serve as a potential prognostic biomarker in colorectal cancer. Further data suggested that it promotes the migration and invasion of colorectal cancer cells via TGFβ/Smad2/3 pathway. Asporin as an ECM protein, which belongs to a small leucine-rich proteoglycan family. In ovarian cancinoma, researchers determined that ASPN is highly expressed in CAFs of high grade serous ovarian cancinoma patients and predicts poor prognosis. Moreover, ASPN may be a potential promising biomarker for heart failure. ASPN protein was reported to significantly increased in ischemic cardiomyopathy and dilated cardiomyopathy left ventricular samples. ASPN protein was significantly increased in ICM and DCM left ventricular samples. In additon, asporin levels will be increased as a result of degeneration in advanced TMJ joint disease with tissue damage.
