Primary Antibodies, Rabbit Polyclonal Antibodies

Boster Bio Anti-Human ICOS DyLight® 488 conjugated Antibody catalog # A00291-Dyl488. Tested in Flow Cytometry applications. This antibody reacts with Human.

Inducible T-cell costimulator is an immune checkpoint protein that in humans is encoded by the ICOS gene. 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.

Flow Cytometry, 1-3μg/1x10⁶ cells

0.5-1mg/ml, actual concentration vary by lot. Use suggested dilution ratio to decide dilution procedure.

E. coli-derived human ICOS recombinant protein (Position: E21-K140).

At -20°C for one year from date of receipt. Avoid repeated freezing and thawing. Protect from light.

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 (By similarity).

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.
