Human RABAC1 ELISA Kit (HUFI06936)

From Assay Genie, this quantitative immunoassay measures human Rab acceptor 1 (RABAC1), an approximately 22 kDa Rab-effector protein involved in vesicular trafficking between endosomes and the Golgi apparatus. RABAC1, also known as PRA1 family protein 1, acts as a docking site for Rab GTPases on intracellular membranes and contributes to vesicle budding, cargo sorting, and membrane identity within the secretory and endocytic pathways.

Researchers studying membrane trafficking, Rab GTPase signaling, neurodegenerative disease models, or viral entry mechanisms can use this kit to quantify endogenous RABAC1 levels in serum or plasma specimens. Each kit provides pre-coated microplate wells, detection antibodies, standards, and substrate reagents for an absorbance-based readout, calibrated against native human RABAC1.

The assay runs on a standard microplate-format ELISA protocol intended for research use only, supporting comparative studies of RABAC1 expression in patient-derived cohorts versus healthy controls, along with cell-based perturbation experiments where Rab-effector interactions are modulated.
