Other Notes
Small volumes of anti-ICOS antibody vial(s) may occasionally become entrapped in the seal of the product vial during shipment and storage. If necessary, briefly centrifuge the vial on a tabletop centrifuge to dislodge any liquid in the container`s cap. Certain products may require to ship with dry ice and additional dry ice fee may apply.
Applications Tested/Suitable for anti-ICOS antibody
Peptide ELISA (EIA)
Application Notes for anti-ICOS antibody
Peptide ELISA: Antibody detection limit dilution 1: 32000.
Western Blot: Preliminary experiments gave an approx 13kDa band in Human Peripheral Blood Lymphocyte lysates after 0. 01ug/ml antibody staining. Please note that currently we cannot find an explanation in the literature for the band we observe given the calculated size of 22.6kDa according to NP_036224.1. The 13kDa band was successfully blocked by incubation with the immunizing peptide.

NCBI Summary for ICOS
The protein encoded by this gene belongs to the CD28 and CTLA-4 cell-surface receptor family. It forms homodimers and plays an important role in cell-cell signaling, immune responses, and regulation of cell proliferation. [provided by RefSeq, Jul 2008]
UniProt Comments for ICOS
ICOS: 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. Defects in ICOS are the cause of immunodeficiency common variable type 1 (CVID1). CVID1 is a primary immunodeficiency characterized by antibody deficiency, hypogammaglobulinemia, recurrent bacterial infections and an inability to mount an antibody response to antigen. The defect results from a failure of B-cell differentiation and impaired secretion of immunoglobulins; the numbers of circulating B-cells is usually in the normal range, but can be lo. 2 isoforms of the human protein are produced by alternative splicing.
