Recombinant Human VSIR protein, Avi & Fc-tagged, Biotinylated

• Cat.No.: VSIR-1288H
• Product Overview: Biotinylated Human B7-H5 Protein, Fc Tag is expressed from human 293 cells (HEK293). It contains AA Phe 33 - Ala 194 (Accession # AAH20568.1). Biotinylation of this product is performed using Avitag technology. Briefly, the single lysine residue in the Avitag is enzymatically labeled with biotin. The biotin to protein ratio is 0.5-1 as determined by the HABA assay.

Specification

• Description: Platelet receptor Gi24, also known as B7-H5 and stress-induced secreted protein-1 (Sisp-1), is a protein that in humans is encoded by the C10orf54 gene, which contains 1 Ig-like (immunoglobulin-like) domain. As for C10orf54 gene, C10orf54 appears to positively interact with BMP-4, potentiating BMP signaling and the transition from an undifferentiated to a differentiated state on ESCs. Human C10orf54 undergoes proteolytic cleavage by MT1-MMP, generating a soluble 30 kDa extracellular fragment plus a 25-30 kDa membrane-bound fragment.
• Source: HEK293
• Species: Human
• Tag: Fc&Avi
• Predicted N Terminal: Phe 33
• Form: Lyophilized from 0.22 μm filtered solution in 50 mM Tris, 100 mM Glycine, pH7.5, 10% trehalose.
• Molecular Mass: The protein has a calculated MW of 47.1 kDa. The protein migrates as 55-66 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.
• Protein length: Phe 33 - Ala 194
• Endotoxin: Less than 1.0 EU per μg by the LAL method.
• Purity: >95% as determined by SDS-PAGE.
• Storage: For long term storage, the product should be stored at lyophilized state at -20°C or lower.
  Please avoid repeated freeze-thaw cycles.
  No activity loss is observed after storage at:
  4-8°C for 12 months in lyophilized state;
  -70°C for 3 months under sterile conditions after reconstitution
• 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℃ before opening to recover the entire contents.
