Product Specific Information
The ISA-3 monoclonal antibody reacts with human ICOS (Inducible COStimulatory molecule), also known as H4, CRP-1, and AILIM. ICOS is a T cell-specific activation molecule and a member of the CD28/CTLA-4 family. It plays a crucial role in T cell activation and humoral immune responses, particularly in memory B cell and plasma cell generation.
ICOS binds to its ligand B7h/B7RP-1 on activated antigen-presenting cells and inflamed tissues. Plate-bound ISA-3 induces T cell costimulation and cytokine production (IL-4, IL-5, IL-10) but not IL-2. The clone C398.4A (anti-mouse ICOS/H4) cross-reacts with human ICOS but binds a different epitope.
For brightest staining of ICOS on activated human T cells, use Product #13-9948-82 or Product #12-9948-42.
Applications Reported: Flow cytometric analysis.
Applications Tested: Pre-diluted and tested on stimulated human peripheral blood cells. Use 5 µL (0.25 µg) per test (100 µL total volume).
Light Sensitivity: Protect from light due to photo-induced oxidation.
Fixation: Samples can be stored in IC Fixation Buffer (Product #00-8222-49) or 1-step Fix/Lyse Solution (Product #00-5333-57) for up to 3 days at 4°C in the dark.
Excitation: 488–561 nm
Emission: 695 nm
Laser Compatibility: Blue, Green, Yellow-Green Lasers
Target Information
ICOS (CD278) encodes a protein of the CD28/CTLA-4 receptor family. It functions as a homodimer and is essential for cell-cell signaling, immune response regulation, and cell proliferation. ICOS is associated with disorders such as Common Variable Immunodeficiency.
