Preparation and Storage
推奨アッセイ手順
For optimal and reproducible results, BD Horizon Brilliant™ Stain Buffer should be used anytime BD Horizon Brilliant™ dyes are used in a multicolor flow cytometry panel. Fluorescent dye interactions may cause staining artifacts which may affect data interpretation. The BD Horizon Brilliant Stain Buffer was designed to minimize these interactions. When BD Horizon Brilliant Stain Buffer is used in in the multicolor panel, it should also be used in the corresponding compensation controls for all dyes to achieve the most accurate compensation. For the most accurate compensation, compensation controls created with either cells or beads should be exposed to BD Horizon Brilliant Stain Buffer for the same length of time as the corresponding multicolor panel. More information can be found in the Technical Data Sheet of the BD Horizon Brilliant Stain Buffer (Cat. No. 563794/566349) or the BD Horizon Brilliant Stain Buffer Plus (Cat. No. 566385).
Product Notices
- Since applications vary, each investigator should titrate the reagent to obtain optimal results.
- An isotype control should be used at the same concentration as the antibody of interest.
- Source of all serum proteins is from USDA inspected abattoirs located in the United States.
- Caution: Sodium azide yields highly toxic hydrazoic acid under acidic conditions. Dilute azide compounds in running water before discarding to avoid accumulation of potentially explosive deposits in plumbing.

The C398.4A monoclonal antibody specifically binds to Inducible Costimulator (ICOS), which is also known as, CD278, Activation-inducible lymphocyte immunomediatory molecule (AILIM), or H4. ICOS is a type I transmembrane glycoprotein that forms a disulfide-linked homodimer and belongs to the CD28 family within the Ig superfamily. ICOS is expressed on either CD4+ or CD8+ single-positive mature thymocytes, T cells, or subsets of Innate Lymphoid Cells (ILC). Its expression is upregulated on activated T lymphocytes. ICOS is a costimulatory receptor that can bind to the B7-H2 ligand (CD275, ICOS-L) that is expressed on B cells, monocytes, macrophages, dendritic cells, and endothelial cells. ICOS plays a critical role in many types of T cell-dependent immunity. In the case of humoral immunity, for example, ICOS signaling is critical for the differentiation of T follicular helper (Tfh) cells and development of germinal centers. Although C398.4A was generated against mouse ICOS, this antibody reportedly crossreacts with human, rhesus, and rat ICOS.
