Active Recombinant Human RSPO2 Protein(186 Leu/Pro), Fc-tagged

• Cat.No.: RSPO2-480H
• Product Overview: Active Recombinant Human RSPO2 Protein(Q6UXX9-1) (Met 1-Gly 205, 186 Leu/Pro) was expressed in HEK293, fused with the Fc region of human IgG1 at the C-terminus.

Specification

• Species: Human
• Source: HEK293
• Tag: Fc
• Protein Length: 1-205 aa
• Form: Lyophilized from sterile PBS, pH 7.4.
• Bio-activity: Measured by its ability to induce activation of catenin response in a Topflash Luciferase assay using HEK293T human embryonic kidney cells. The ED50 for this effect is typically 10-60 ng/mL in the presence of 5 ng/mL recombinant mouse Wnt3a.
• Molecular Mass: The secreted recombinant human RSPO2/Fc is a disulfide-linked homodimer. The reduced monomer comprises 425 amino acids and has a predicted molecular mass of 48.3 kDa. ?The apparent molecular mass of rh RSPO2/Fc monomer is approximately 50 kDa in SDS-PAGE under reducing conditions.
• Endotoxin: < 1.0 EU per μg of the protein as determined by the LAL method.
• Purity: > 90 % as determined by SDS-PAGE
• Storage: Store it under sterile conditions at -20°C to -80°C upon receiving. Recommend to aliquot the protein into smaller quantities 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.
