Human SEMA4B ELISA Kit (HUFI06613)

The Human SEMA4B ELISA Kit from Assay Genie quantifies Semaphorin-4B, a class 4 transmembrane semaphorin implicated in neuronal axon guidance, immune cell signaling, and tumor microenvironments of gastric, breast, and non-small cell lung carcinoma. The capture antibody is human-specific, with no significant cross-reactivity reported against the murine Sema4b ortholog, supporting selective measurement of endogenous human protein in serum or plasma specimens drawn from clinical and experimental cohorts. Each kit ships with a pre-coated microplate, biotinylated detection reagent, streptavidin-HRP conjugate, a serial dilution series of calibrated standards, wash buffer, and TMB substrate, providing enough material to develop the entire plate in a single assay run. Reagents should be stored refrigerated upon arrival, and once opened, individual components are best aliquoted and frozen to limit freeze-thaw cycles and preserve antibody binding performance across repeated experiments.
