bsm-70649M

DATASHEET

Host: Mouse

Target Protein: Semaphorin-3A (Central region)

Specificity: 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. The sequence used is highly conserved in rat and mouse Sema3A, and has low homology to other semaphorin family members.

Clonality: Monoclonal

Isotype: IgG1

Swiss Prot: Q14563

Source: Clone M317 was generated from a synthetic peptide (coupled to carrier protein) corresponding to amino acids in the central region of human Sema3A.

Purification: Antigen Affinity purification

Storage Buffer: PBS + 1 mg/ml BSA, 0.05% NaN3 and 50% glycerol

Storage: Storage at -20°C is recommended, as aliquots may be taken without freeze/thawing due to presence of 50% glycerol. Stable for at least 1 year at -20°C.

Background:

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.
