Semaphorins 3A, 3E, 3F, and 4D

Antibody Sampler Kit

$395

One family of inhibitory axon guidance molecules is the semaphorins. The semaphorins include secreted, transmembrane, and GPI-anchored extracellular molecules that have been implicated in neuron development, vascular disease, and tumor progression. There are eight classes of semaphorin genes, all of which are characterized by a conserved 500 amino acid, cystine-rich Sema domain. Semaphorin 3A (Sema-3A) binds its co-receptors, Neuropilin-1 and Plexin A1, and this interaction has been implicated in suppressing axon regeneration after injury. Sema-3E binds Plexin D1 receptor, and has putative roles in axon guidance, angiogenesis, and cancers. The Sema-3E protein is expressed as full length (87 kDa) and furin-dependent processed forms (61 and 25 kDa). Sema-3F binds with high affinity to Neuropilin-2, and low affinity to Neuropilin-1. Sema-3F has been implicated in neuronal development, angiogenesis, and tumor progression. Sema-4D binds Plexin B1, and this pathway may be involved in cell survival and angiogenesis.

Western blots of neonatal rat brain (lanes 1, 3, & 5) and human recombinant Sema3A/Fc chimera (95/125 kDa) (lanes 2, 4, & 6). Blots were probed with anti-Sema3A (SP1401) (lanes 1 & 2), anti-Sema3A (SP1221) (lanes 3 & 4) and anti-Sema3A (SP1241) (lane 5 & 6).

Western blot image of mouse brain lysate. The blot was probed with mouse monoclonal Semaphorin-4D antibody (SM1881) at 1:250 (lane 1), 1:500 (lane 2), and 1:1000 (lane 3).

KIT SUMMARY

The Semaphorin antibody kit can be used to compare the expression of Sema-3A, Sema-3E, Sema-3F, and Sema-4D in cells and tissues. The kit includes three Sema-3A antibodies that target the N-terminal, Central, and C-terminal regions of Sema-3A.
