Human Semaphorin 4A / SEMA4A / Semaphorin B Protein (Fc Tag)

Sino Biological


A DNA sequence encoding the human SEMA4A (NP_071762.2) extracellular domain (Met 1-His 683) was fused with the Fc region of human IgG1 at the C-terminus.


  • Tag: C-human IgG1-Fc
  • Purity: > 90 % as determined by SDS-PAGE
  • Source: HEK293 Cells
  • Species: Human
  • Storage: Store it under sterile conditions at -20℃ to -80℃. It is recommended that the protein be aliquoted for optimal storage. Avoid repeated freeze-thaw cycles.
  • Molecule: SEMA4A
  • Endotoxin: < 1.0 EU per μg of the protein as determined by the LAL method
  • Lead Time: 1-3 days
  • Formulation: Lyophilized from sterile PBS, pH 7.4
  • Molecular Mass: The secreted recombinant human SEMA4A/Fc chimera is a disulfide-linked homodimer. The reduced monomer consists of 893 amino acids and predictes a molecular mass of 99 kDa. In SDS-PAGE under reducing conditions, the apparent molecular mass of rh SEMA4A/Fc monomer is approximately 110 kDa due to glycosylation.
  • Reconstitution: A hardcopy of datasheet with reconstitution instructions is sent along with the products. Please refer to it for detailed information.
  • Accession Number: NP_071762.2
  • Predicted N Terminal: Gly 32
