Target

  • Function
    Enhances all basic T-cell responses to a foreign antigen, namely proliferation, secretion of lymphokines, up-regulation of molecules that mediate cell-cell interaction, and effective help for antibody secretion by B-cells. Essential both for efficient interaction between T and B-cells and for normal antibody responses to T-cell dependent antigens. Does not up-regulate the production of interleukin-2, but superinduces the synthesis of interleukin-10. Prevents the apoptosis of pre-activated T-cells. Plays a critical role in CD40-mediated class switching of immunoglobin isotypes.
  • Tissue specificity
    Activated T-cells. Highly expressed on tonsillar T-cells, which are closely associated with B-cells in the apical light zone of germinal centers, the site of terminal B-cell maturation. Expressed at lower levels in thymus, lung, lymph node and peripheral blood leukocytes. Expressed in the medulla of fetal and newborn thymus.
  • Involvement in disease
    Immunodeficiency, common variable, 1
  • Sequence similarities
    Contains 1 Ig-like V-type (immunoglobulin-like) domain.
  • Post-translational
    modifications
    N-glycosylated.
  • Cellular localization
    Secreted and Cell membrane.

Customer reviews and Q&As

Answer

I contacted the laboratories and they confirmed that the antigen retrieval protocol used when testing ab175401Anti-ICOS antibody in IHC-P was as follows:

Fully Immerse the slide in Tris EDTA buffer pH 9.0, cooked for 10-15 min with medium-low heat, cook 10-15min more after power off for 10 min.(avoid drying out), cooling down at room temperature, and washed with PBS buffer pH 7.4 (3*5min).

Please note this may require some individual optimization.
