ARHI Protein, Human, Recombinant (mFc Tag)

• Background:

  ARHI, also known as DIRAS3, belongs to the small GTPase superfamily, Di-Ras family. ARHI gene is a novel tumor suppressor gene located on chromosome 1p31. Downregulation of ARHI expression has been detected in many types of cancer. ARHI is expressed in normal ovarian and breast epithelial cells but not in ovarian and breast cancers. As a suppressor, ARHI is not only an important factor in the pathogenesis of gastric cancer, but also a potential factor for tumor aggravation. ARHI expression in gastric cancer can be employed to indicate favorable prognosis for the disease.

• Gene Name:

  DIRAS family, GTP-binding RAS-like 3

• UniProt:

  O95661

• Expression System:

  HEK293 Cells

• Tag:

  N-mFc

• Endotoxin:

  < 1.0 EU per μg of the protein as determined by the LAL method.

• Purity:

  > 85 % as determined by SDS-PAGE.

• Activity:

  At Leading Biology, the biological activity of a recombinant protein is routinely measured using a bioassay, e.g. chemotaxis or cell proliferation assay, enzyme assay, or a functional ELISA. When a recombinant protein is an enzyme, specific activity is derived from an enzymatic assay. Each enzyme is tested for potency by cleavage of a substrate. We are in the process of updating the biological activity data. If you have any questions regarding this update, please feel free to contact our technical support team.

• Form:

  Lyophilized

• Buffer:

  Lyophilized from sterile PBS, pH 7.4. Please contact us for any concerns or special requirements. Normally 5 % - 8 % trehalose, mannitol and 0.01% Tween 80 are added as protectants before lyophilization. Please refer to the specific buffer information in the hard copy of CoA.

• Molecular Weight:

  The recombinant human DIRAS3/mFc comprises 461 amino acids and has a predicted molecular mass of 52.1 kDa. The apparent molecular mass of the monomer is approximately 62 kDa in SDS-PAGE under reducing conditions due to glycosylation.

• Storage Conditions:

  In general, recombinant proteins are provided as lyophilized powder which are shipped at ambient temperature. Bulk packages of recombinant proteins are provided as frozen liquid. They are shipped out with blue ice unless customers require otherwise. Stable for 1 year at -20°C or below from date of shipment. For maximum recovery of product, centrifuge the original vial after thawing and opening the cap. For long-term storage, aliquot and store at -20°C or below. Avoid repeated freeze-thaw cycles.
