ICOS is a T cell specific activation molecule and a third member of the CD28\/CTLA-4 family. Human ICOS has a relative molecular mass of 55-60 kDa, composed of 27 kDa and 29 kDa chains. Human ICOS on activated T cells has potent costimulatory activity for T cell activation and is required for humoral immune responses, in particular for memory B cell and plasma cell generation. ICOS binds to its ligand, B7h\/B7RP-1 expressed on activated APCs (antigen presenting cells) and on a number of inflamed peripheral tissues. Plate-bound ISA-3 is costimulatory for T cells and induces production of IL-4, IL-5, IL-10 and other cytokines, but not IL-2. ISA-3 has the same reactivity pattern and characteristics as F44. ISA-3 was generated against the human ICOS antigen.

C398.4A stains activated cells brighter than ISA-3; however, it also exhibits higher staining of non-activated human peripheral blood or isolated PBMC.

This can be used at less than or equal to 5 µL (0.6 µg) per test. A test is defined as the amount (µg) of antibody that will stain a cell sample in a final volume of 100 µL. Cell number should be determined empirically but can range from 10^5 to 10^8 cells\/test. It is recommended that the antibody be carefully titrated for optimal performance in the assay of interest.\u003c\/p\u003e\u003cp\u003eNovaFluor dyes are not compatible with DNA intercalating viability dyes. Do not use viability dyes such as propidium iodide, 7-actinomycin D (7-AAD) and DAPI.

This buffer contains formulation improvements over CellBlox. CellBlox Plus Blocking Buffer is required for optimal staining with NovaFluor conjugates and should be used in all experiments where NovaFluor conjugates are used. Whenever possible, we recommend adding CellBlox Plus Blocking Buffer to antibody cocktails\/master mixes prior to combining with cells. Add 5 µL per sample (regardless of the number of NovaFluors in your panel) to use the antibody cocktail as intended. For single-color controls, use 5 µL of CellBlox Blocking Buffer per 100 µL of cell sample containing 10^3 to 10^8 cells.\u003c\/p\u003e\u003cp\u003eNovaFluor conjugates are based on Phiton™ technology utilizing novel nucleic acid dye structures that allow for engineered fluorescent signatures with consideration for spillover and spread impacts. \u003ca href=\"https:\/\/www.thermofisher.com\/us\/en\/home\/life-science\/cell-analysis\/flow-cytometry\/novafluor-dyes.html\"\u003eLearn more \u003c\/a\u003e\u003c\/p\u003e\u003cp\u003eExcitation: 552 nm; Emission: 700 nm; Laser: 561 nm (Yellow) Laser\u003c\/p\u003e\u003cp\u003e .\u003c\/p\u003e\u003cp\u003e \u003c\/p\u003eFor Research Use Only.
