Recombinant Human HRG protein(Met 1-Lys 525), His-tagged

• Cat.No.: HRG-753H
• Product Overview: Recombinant Human HRG protein(NP_000403.1) (Met 1-Lys 525) with a C-terminal polyhistidine tag was expressed in HEK293.

Specification

• Species: Human
• Source: HEK293
• Tag: His
• Protein Length: 1-525 a.a.
• Form: Lyophilized from sterile PBS, pH 7.4.
• Bio-activity: Measured by its ability to support the adhesion of MOLT-4 human acute lymphoblastic leukemia cells. (Lamb-Wharton, R.J. and W.T. Morgen, 1993, Cell Immunol. 152: 544). Human HPRG immobilized at 1 μg/ml (100 μl/well) will induce >65% MOLT4 cell adhesion (1 x 10E5 cells/well) in the presence of 7.5 μg/ml Concanvalin A.
• Molecular Mass: The secreted recombinant human HPRG comprises 518 amino acids with a predicted molecular mass of 59 kDa. As a result of glycosylation, rhHPRG migrates as an approximately 75-80 kDa band in SDS-PAGE under reducing conditions.
• Endotoxin: < 1.0 EU per μg of the protein as determined by the LAL method
• Purity: ≥ 95 % as determined by SDS-PAGE
• Storage: Samples are stable for up to twelve months from date of receipt at -20°C to -80°C. Store it under sterile conditions at -20°C to -80°C. It is recommended that the protein be aliquoted for optimal storage. Avoid repeated freeze-thaw cycles.
• Reconstitution: It is recommended that sterile water be added to the vial to prepare a stock solution of 0.2 ug/ul. Centrifuge the vial at 4°C before opening to recover the entire contents.
