Filter:
  • Western Blot (WB) analysis of various lysates using RAB27B Monoclonal antibody (66944-1-Ig)

    WB analysis using 66944-1-Ig (same clone as 66944-1-PBS)

    Various lysates were subjected to SDS PAGE followed by western blot with 66944-1-Ig (RAB27B antibody) at dilution of 1:3000 incubated at room temperature for 1.5 hours. This data was developed using the same antibody clone with 66944-1-PBS in a different storage buffer formulation.

  • Western Blot (WB) analysis of human peripheral blood platelets using RAB27B Monoclonal antibody (66944-1-Ig)

    WB analysis of human peripheral blood platelets using 66944-1-Ig (same clone as 66944-1-PBS)

    human peripheral blood platelets were subjected to SDS PAGE followed by western blot with 66944-1-Ig (RAB27B antibody) at dilution of 1:3000 incubated at room temperature for 1.5 hours. This data was developed using the same antibody clone with 66944-1-PBS in a different storage buffer formulation.

  • Immunohistochemistry (IHC) staining of human lung cancer tissue using RAB27B Monoclonal antibody (66944-1-Ig)

    IHC staining of human lung cancer using 66944-1-Ig (same clone as 66944-1-PBS)

    Immunohistochemical analysis of paraffin-embedded human lung cancer tissue slide using 66944-1-Ig (RAB27B antibody) at dilution of 1:200 (under 10x lens. Heat mediated antigen retrieval with Tris-EDTA buffer (pH 9.0). This data was developed using the same antibody clone with 66944-1-PBS in a different storage buffer formulation.

    IF Staining of A431 using 66944-1-Ig (same clone as 66944-1-PBS)

    Immunofluorescent analysis of (-20°C Methanol) fixed A431 cells using RAB27B antibody (66944-1-Ig, Clone: 2B9G9 ) at dilution of 1:400 and CoraLite®488-Conjugated Goat Anti-Mouse IgG(H+L). This data was developed using the same antibody clone with 66944-1-PBS in a different storage buffer formulation.

  • Flow cytometry (FC) experiment of A431 cells using RAB27B Monoclonal antibody (66944-1-Ig)

    FC experiment of A431 using 66944-1-Ig (same clone as 66944-1-PBS)

    1x10^6 A431 cells were intracellularly stained with 0.4 ug Anti-Human RAB27B (66944-1-Ig, Clone:2B9G9) and CoraLite®488-Conjugated Goat Anti-Mouse IgG(H+L) at dilution 1:1000 (red), or 0.4 ug Mouse IgG2a isotype control Mouse McAb (66360-2-Ig, Clone: 11A1B2) (blue). Cells were fixed with 4% PFA and permeabilized with Flow Cytometry Perm Buffer (PF00011-C). This data was developed using the same antibody clone with 66944-1-PBS in a different storage buffer formulation.

Background Information

The Rab27 GTPase subfamily consists of two closely related homologs, Rab27a and Rab27b. Northern blot analysis revealed that Rab27b is expressed significantly only in testis, in which the predominant transcript was 1.4 kb in size. An 8-kb mRNA of unknown origin was detected in many tissues. Rab27b is associated with tubulovesicle membranes in the parietal cell and Rab27b may play a role in stimulation-associated membrane recruitment and gastric acid secretion. Rab27b is recently reported as a marker for breast cancer progression. It regulates invasive growth and metastasis in ER-positive breast cancer cell lines, and increased expression is associated with poor prognosis in humans.
