Product Description
Small GTPases are a super-family of cellular signaling regulators. Rab5 is a member of the Rab-family GTPases. Rab5 is a rate-limiting component of the machinery regulating the kinetics of membrane traffic in the early endocytic pathway.
Currently there is no direct assay to measure the activation of Rab5 GTPases.
Bioyears Biosciences Rab5B Activation Assay Kit is based on the configuration-specific monoclonal antibody that specifically recognizes Rab5-GTP, but not Rab5-GDP, and a Rab5B specific rabbit polyclonal antibody. Given the high affinity of monoclonal antibodies to their antigens, the activation assay could be performed in a short time. This assay provides the reliable results with consistent reproducibility.
This anti Rab5 GTP monoclonal antibody can also be used to monitor the activation of Rab5 in cells and in tissues by immunohistochemistry.
Bioyears Biosciences Rab5B Activation Assay Kit provides a simple and fast method to monitor the activation of Rab5B. Each kit provides sufficient quantities to perform 20 assays.

Assay Principle
Bioyears Biosciences Rab5B Activation Assay Kit bases on the configuration-specific anti Rab5 GTP monoclonal antibody to measure the active Rab5B-GTP levels, either from cell extracts or from in vitro GTPγS loading Rab5B activation assays. Briefly, anti active Rab5 mouse monoclonal antibody will be incubated with cell lysates containing Rab5-GTP. The bound active Rab5 will then be pulled down by protein A/G agarose. The precipitated active Rab5B will be detected by immunoblot analysis using anti Rab5B specific rabbit polyclonal antibody.
Kit Components
1. Anti active Rab5, Mouse Monoclonal Antibody (Catalog No. 26911): One vial – 22 µL (1
mg/ml) in PBS, pH 7.4, containing 50% glycerol and 0.05% sodium azide. This antibody
specifically recognizes Rab5-GTP from all vertebrates.
2. Protein A/G Agarose (Catalog No. 30301): One vial – 400 µL of 50% slurry.
3. 5X Assay/Lysis Buffer (Catalog No. 30302): One bottle – 30 mL of 250 mM Tris-HCl, pH 8, 750 mM NaCl, 50 mM MgCl2, 5 mM EDTA, 5% Triton X-100.
4. Anti Rab5B, Rabbit Polyclonal Antibody (Catalog No. 21037): One vial – 100 µL (0.2 mg/ml)
in PBS, pH 7.4, contained 50% glycerol.
5. 100 X GTPγS (Catalog No. 30303): One vial –100 µl at 10 mM, use 5 µL of GTPγS for
GTP-labeling of 0.5 mL of cell lysate.
6. 100 X GDP (Catalog No. 30304): One vial –100 µl at 100 mM, use 5 µL of GDP for
GDP-labeling of 0.5 mL of cell lysate.
