Application Abreviews Notes
IHC-Fr Use at an assay dependent concentration.
Blocking Use at an assay dependent concentration. The antibody blocks IL6 induced proliferation of XG-1 cells.
Inhibition Assay Use at an assay dependent concentration. The antibody inhibits IL6 binding to its receptor.
Flow Cyt Use at an assay dependent concentration.

ab170190 - Mouse monoclonal IgG1, is suitable for use as an isotype control with this antibody.


IP Use at an assay dependent concentration.


  • Function
    Part of the receptor for interleukin 6. Binds to IL6 with low affinity, but does not transduce a signal. Signal activation necessitate an association with IL6ST. Activation may lead to the regulation of the immune response, acute-phase reactions and hematopoiesis.
    Low concentration of a soluble form of IL6 receptor acts as an agonist of IL6 activity.
  • Tissue specificity
    Isoform 2 is expressed in peripheral blood mononuclear cells and weakly found in urine and serum.
  • Sequence similarities
    Belongs to the type I cytokine receptor family. Type 3 subfamily.
    Contains 1 fibronectin type-III domain.
    Contains 1 Ig-like C2-type (immunoglobulin-like) domain.
  • Domain
    The two fibronectin type-III-like domains, contained in the N-terminal part, form together a cytokine-binding domain.
    The WSXWS motif appears to be necessary for proper protein folding and thereby efficient intracellular transport and cell-surface receptor binding.
  • Post-translational
    A short soluble form may also be released from the membrane by proteolysis.
  • Cellular localization
    Secreted and Basolateral cell membrane.
