Protein Description	Recombinant Human Semaphorin 3A Fc is a glycosylated, disulfidelinked homodimer of 1,976 amino acid residues, which includes the SEMA domain, immunoglobulin c2-like domain, and the C-terminal basic Arg/Lys-rich domain of the mature sequence, as well as an 8- residue N-terminal His-tag and a 230-residue C-terminal Fc region linked by two glycines.
Storage	Store lyophilized at 2-8°C for 6 months or at -20°C long term. After reconstitution store the antibody undiluted at 2-8°C for one month  or (in aliquots) at -20°C long term. Avoid repeated freezing and thawing.
Stability	Shelf life: one year from despatch.
Bioactivity	Biological: Determined by its ability to bind recombinant Rat Neuropilin-1 Fc Chimera in a functional ELISA assay.
Endotoxin	< 0.1 ng/ug of protein (< 1 EU/ug)

Summary	This gene is a member of the semaphorin family and encodes a protein with an Ig-like C2-type (immunoglobulin-like) domain, a PSI domain and a Sema domain. This secreted protein can function as either a chemorepulsive agent, inhibiting axonal outgrowth, or as a chemoattractive agent, stimulating the growth of apical dendrites. In both cases, the protein is vital for normal neuronal pattern development. Increased expression of this protein is associated with schizophrenia and is seen in a variety of human tumor cell lines. Also, aberrant release of this protein is associated with the progression of Alzheimer's disease. [provided by RefSeq, Jul 2008]
