Human Semaphorin-4B (SEMA4B) ELISA Kit

Semaphorin-4B is a protein encoded by the SEMA4B gene. Members of the collapsin/semaphorin gene family have been proposed to act as growth cone guidance signals in vertebrates and invertebrates. To identify candidate molecules involved in axonal pathfinding during mouse embryogenesis, isolated cDNAs encoding five new members of the semaphorin family (Sem A-Sem E) . The murine semaphorin genes are differentially expressed in mesoderm and neuroectoderm before and during the time when axons select their pathways in the embryo. In explant cultures, recombinant Sem D/collapsin converts a matrix permissive for axonal growth into one that is inhibitory for neurites of peripheral ganglia. Semaphorins are a diverse family of molecules that may provide local signals to specify territories nonaccessible for growing axons.

Human Semaphorin-4B (SEMA4B) ELISA Kit has high sensitivity and excellent specificity for detection of Human SEMA4B. No significant cross-reactivity or interference between Human SEMA4B and analogues was observed.

This Human Semaphorin-4B (SEMA4B) ELISA Kit employs a two-site sandwich ELISA to quantitate SEMA4B in samples. An antibody specific for SEMA4B has been pre-coated onto a microplate. Standards and samples are pipetted into the wells and anySEMA4B present is bound by the immobilized antibody. After removing any unbound substances, a biotin-conjugated antibody specific for SEMA4B 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 SEMA4B bound in the initial step. The color development is stopped and the intensity of the color is measured.

• 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 °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.
