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

CORD10,RP35,SEMAB,SEMB

Catalog Number	P11756-H02H
Organism Species	Human
Host	Human Cells
Synonyms	CORD10,RP35,SEMAB,SEMB
Molecular Weight	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.
predicted N	Gly 32
SDS-PAGE
Purity	> 90 % as determined by SDS-PAGE
Protein Construction	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.
Bio-activity	Measured by its ability to bind mouse SEMA4D in a functional ELISA.
Research Area	Cancer \|Invasion microenvironment \|Angiogenesis \|Angiogenesis Inhibitor
Formulation	Lyophilized from sterile PBS, pH 7.4 1. Normally 5 % - 8 % trehalose and mannitol are added as protectants before lyophilization. Specific concentrations are included in the hardcopy of COA.
