Product Notices

  1. Since applications vary, each investigator should titrate the reagent to obtain optimal results.
  2. Please refer to for technical protocols.
  3. Caution: Sodium azide yields highly toxic hydrazoic acid under acidic conditions. Dilute azide compounds in running water before discarding to avoid accumulation of potentially explosive deposits in plumbing.
  4. Source of all serum proteins is from USDA inspected abattoirs located in the United States.

The members of the Ras superfamily of GTPases, which now includes more than 50 different proteins, shuttle between the GDP-bound inactive position and the GTP-bound active state. The GTPase activity of the Ras-like proteins is regulated by effectors that promote either the GDP- or the GTP-bound states. GTPases of the Ras superfamily have a role in controlling numerous events such as cell proliferation, nucleocytoplasmic transport, and vesicular traffic. The Rab superfamily of proteins includes more than 30 different members that are involved in the regulation of different steps of vesicular traffic. Subcellular localization and specific cellular function of each Rab appears to be encoded in the unique C-terminal part of the proteins, known as the hypervariable region. The 207 amino acid Rab8 protein is closely related to the yeast Sec4p and regulates vesicle transport from the Trans-golgi Network to the basolateral plasma membrane in epithelial cells. In addition, Rab8 interacts with the stress-activated kinase rab8p, a close homologue of the GC Kinase. This interaction was found to be dependent on GTP.

This antibody is routinely tested by western blot analysis. Other applications were tested at BD Biosciences Pharmingen during antibody development only or reported in the literature.

Format Details
Down Arrow Up Arrow
Tissue culture supernatant is purified by either protein A/G or affinity purification methods. Both methods yield antibody in solution that is free of most other soluble proteins, lipids, etc. This format provides pure antibody that is suitable for a number of downstream applications including: secondary labeling for flow cytometry or microscopy, ELISA, Western blot, etc.
