Usage Notes
* Do not mix components from different kit lots or use reagents beyond the kit expiration date.
* Allow all reagents to warm to room temperature for at least 30 minutes before opening.
* Pre-rinse the pipet tip with reagent, use fresh pipet tips for each sample, standard and reagent to avoid contamination.
* Unused wells must be kept desiccated at 4 degree C in the sealed bag provided.
* Mix Thoroughly is very important for the result. It is recommended using low frequency oscillator or slight hand shaking every 10 minutes.
* It is recommended that all samples and standards be assayed in duplicate or triplicate.
Preparation and Storage
Store at 2-8 degree C.

Description: This Human Semaphorin-4A (SEMA4A) ELISA Kit employs a two-site sandwich ELISA to quantitate SEMA4A in samples. An antibody specific for SEMA4A has been pre-coated onto a microplate. Standards and samples are pipetted into the wells and any SEMA4A present is bound by the immobilized antibody. After removing any unbound substances, a biotin-conjugated antibody specific for SEMA4A is added to the wells. After washing, Streptavidin conjugated Horseradish Peroxidase (HRP) is added to the wells. Following a wash to remove any unbound avidin-enzyme reagent, a substrate solution is added to the wells and color develops in proportion to the amount of SEMA4A bound in the initial step. The color development is stopped and the intensity of the color is measured.

Background: SEMA4A is a member of the semaphorin family of soluble and transmembrane proteins. Semaphorins are involved in guidance of axonal migration during neuronal development and in immune responses.Mice treated with Sema4a had enhanced priming of antigen-specific T cells secreting both IL4 and gamma-interferon (IFNG). Treatment of mice with anti-Sema4a early after immunization with myelin oligodendrocyte glycoprotein suppressed the development of experimental autoimmune encephalomyelitis. In these mice, infiltration of mononuclear inflammatory cells was ablated by inhibition of the generation of antigen-specific T cells by anti-Sema4a. Expression cloning determined that the high-affinity receptor for Sema4a is Tim2. Sema4a stimulation of cells expressing Tim2 induced tyrosine phosphorylation of Tim2 but not of Tim3.

NCBI Description

This gene encodes a member of the semaphorin family of soluble and transmembrane proteins. Semaphorins are involved in numerous functions, including axon guidance, morphogenesis, carcinogenesis, and immunomodulation. The encoded protein is a single-pass type I membrane protein containing an immunoglobulin-like C2-type domain, a PSI domain and a sema domain. It inhibits axonal extension by providing local signals to specify territories inaccessible for growing axons. It is an activator of T-cell-mediated immunity and suppresses vascular endothelial growth factor (VEGF)-mediated endothelial cell migration and proliferation in vitro and angiogenesis in vivo. Mutations in this gene are associated with retinal degenerative diseases including retinitis pigmentosa type 35 (RP35) and cone-rod dystrophy type 10 (CORD10). Multiple alternatively spliced transcript variants encoding different isoforms have been identified.[provided by RefSeq, Sep 2010]

Product Notes

The Human SEMA4A sema4a (Catalog #AAA9714378) is an ELISA Kit and is intended for research purposes only. The product is available for immediate purchase. The AAA9714378 ELISA Kit recognizes Human SEMA4A. It is sometimes possible for the material contained within the vial of "Semaphorin-4A (SEMA4A), ELISA Kit" to become dispersed throughout the inside of the vial, particularly around the seal of said vial, during shipment and storage. We always suggest centrifuging these vials to consolidate all of the liquid away from the lid and to the bottom of the vial prior to opening. Please be advised that certain products may require dry ice for shipping and that, if this is the case, an additional dry ice fee may also be required.
