• Host: Mouse
• Reactivity: Human, Rat, Mouse
• Clonality: Monoclonal
• Isotype: IgG1
• Specificity: This antibody was affinity purified using Semaphorin 3A (Central region) peptide (without carrier). The antibody detects a 95kDa* protein corresponding to the apparent molecular mass of Sema3A on SDS-PAGE immunoblots of human recombinant Sema3A and adult mouse brain lysates.
• Purity/Purification: Affinity Purified
• Form/Format: Supplied in 100ul phosphate-buffered saline, 50% glycerol, 1 mg/ml BSA, and 0.05% sodium azide.
• Sequence Length: 771

• Applicable Applications for anti-SEMA3A antibody: Western Blot (WB), ELISA (EIA)
• Application Notes: ELISA: 1:1000; WB: 1:500; WB: Western blot membranes were incubated with diluted antibody in 5% non-fat milk, PBS, 0.04% Tween20 for 1 hour at room temperature.
• Immunogen: Clone M317 was generated from a synthetic peptide (coupled to carrier protein) corresponding to amino acids in the central region of human Sema3A. The sequence used is highly conserved in rat and mouse Sema3A, and has low homology to other semaphorin family members.
• Preparation and Storage: Store at -20 degree C. Stable for 1 year.

Western Blot (WB)

(Western blots of human recombinant Sema3A/Fc chimera (95/125 kDa) (lanes 1-4). The blots were probed with rabbit polyclonal Sema3A (Central region) at 1:250 (lane 1) and 1:1000 (lane 2) and mouse monoclonal Sema3A (Central region) at 1:250 (lane 3) and 1:1000 (lane 4). Both antibodies recognize the 95 kDa and 125 kDa forms of the recombinant Sema3A.)

One family of inhibitory axon guidance molecules is the semaphorins. The semaphorins include secreted, transmembrane, and GPI-anchored extracellular molecules that are involved in regulating axon guidance by inhibiting axons from growing toward incorrect targets. Semaphorin 3A (Sema3A) may play a particularly interesting role in limiting axon regeneration since it is expressed in meningeal fibroblasts that invade the injured spinal cord and surround the glial scar. In addition, the Sema3A co-receptors, Neuropilin-1 and Plexin-A1, are expressed on axons that regenerate up to the injured region, but do not cross this Sema3A-containing region. Thus, Sema3A and its co-receptors may have important roles in regulating axon guidance during neuronal development and after neuronal injury.

NCBI Description

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]

Uniprot Description

Involved in the development of the olfactory system and in neuronal control of puberty. Induces the collapse and paralysis of neuronal growth cones. Could serve as a ligand that guides specific growth cones by a motility-inhibiting mechanism. Binds to the complex neuropilin-1/plexin-1.
