Human RAB8B, Member RAS Oncogene Family (RAB8B) ELISA Kit

RAB8B is a small GTPase of the Rab family that regulates intracellular vesicular trafficking, polarized exocytosis, and primary cilium biogenesis. In published studies it has been linked to melanoma and thyroid cancer biology, where altered RAB8B expression influences membrane delivery, cell polarity, and downstream signaling. This colorimetric immunoassay from Assay Genie is configured to quantify endogenous human RAB8B protein in serum, plasma, and tissue homogenate samples. It is validated as human-specific, with minimal cross-reactivity observed against rodent Rab8 homologues, supporting comparative cell biology and translational oncology workflows that require species-specific quantitation.
