SpecificityTocilizumab binds specifically to both the membrane bound and soluble forms of human IL-6R. The IL6 receptor is a protein complex consisting of an IL-6 receptor subunit (IL6R) and interleukin 6 signal transducer Glycoprotein 130. Interleukin 6 (IL6) is a potent pleiotropic cytokine that regulates cell growth and differentiation and plays an important role in immune response.
Species ReactivityHuman
Immunogen DescriptionThis antibody was prepared by CDR grafting of mouse AUK 12-20 antibody onto a human framework regions.
ConjugateUnconjugated
Concentration1 mg/mL
Purity DescriptionPurified antibody, via affinity chromatography
Application DetailsTocilizumab can be used in ELISA assays and is able to inhibit the growth of IL-6-dependent tumor cell lines (to the same extent as the original AUK12-20 mouse antibody) - inhibits sIL-6R and mIL-6R-mediated signaling.

Scientific BackgroundThis chimeric rabbit antibody was made using the variable domain sequences of the original Human IgG1 format, for improved compatibility with existing reagents, assays and techniques. Tocilizumab can be used in ELISA assays and is able to inhibit the growth of IL-6-dependent tumor cell lines (to the same extent as the original AUK12-2mouse antibody) - inhibits sIL-6R and mIL-6R-mediated signaling.
Immunofluorescence staining of fixed U937 cells with anti-IL-6 receptorantibody rhPM-1 (Tocilizumab) (R-2034-200) Immunofluorescence analysis of paraformaldehyde fixed U937 cells on Shi-fix™ coverslips, permeabilized with 0.15% Triton and stained with the chimeric rabbit IgG version of rhPM-1 (Tocilizumab) (R-2034-200) at 10 µg/mL for 1h followed by Alexa Fluor® 488 secondary antibody (1 µg/mL), showing membrane staining. The nuclear stain is DAPI (blue). Panels show from left-right, top-bottom R-2034-200, DAPI, merged channels and an isotype control. The isotype control was stained with an anti-Fluorescein antibody (Ab102-23.0) followed by Alexa Fluor® 488 secondary antibody.
