Catalog# CD65 Source Human Cells Description Recombinant Human Semaphorin-3A/SEMA3A is produced by our mammalian expression system in human cells. The target protein is expressed with sequence (Asn21-Val771) of Human SEMA3A fused with a polyhistidine tag at the C-terminus. Names Synonyms: Semaphorin III, SEMA3A, SEMAD, Hsema-I, SEMA1, SemD, Semad, coll-1 , Hsema-III, Sema III Accession # Q14563 Formulation Lyophilized from a 0.2 μm filtered solution of PBS, pH 7.4 Shipping The product is shipped at ambient temperature. Reconstitution Always centrifuge tubes before opening. Do not mix by vortex or pipetting.
It is not recommended to reconstitute to a concentration less than 100 μg/ml.
Dissolve the lyophilized protein in 1X PBS.
Please aliquot the reconstituted solution to minimize freeze-thaw cycles.Storage Lyophilized protein should be stored at < -20°C, though stable at room temperature for 3 weeks.
Reconstituted protein solution can be stored at 4-7°C for 2-7 days.
Aliquots of reconstituted samples are stable at < -20°C for 3 months.Purity Greater than 95% as determined by SEC-HPLC and reducing SDS-PAGE. Endotoxin Less than 0.1 ng/µg (1 IEU/µg).

Semaphorins are a family of secreted and cell-bound signaling molecules defined by the presence of a common 500 aa Sema domain.This 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.
