      Purified Armenian Hamster Anti-ICOS (CD278)
      Purified Armenian Hamster Anti-ICOS (CD278)
      Multiparameter flow cytometric analysis of ICOS (CD278) expression on human peripheral blood leucocyte populations. Human whole blood was stained with either no antibody [for a Fluorescence-Minus-One (FMO) control; Left Plot] or Purified Armenian Hamster Anti-ICOS (CD278) antibody (Cat. No. 567906; Right Plot] at 0.125 µg/test followed by PE Mouse Anti-Armenian and Syrian Hamster IgG Cocktail (Cat. No. 554056). The erythrocytes were lysed with BD Pharm Lyse™ Lysing Buffer (Cat. No. 555899). A bivariate pseudocolor density plot showing the correlated expression of ICOS (CD278) (or FMO control) versus side-light scatter (SSC-A) signals was derived from gated events with the forward and side-light scatter characteristics of intact leucocyte populations. Flow cytometry and data analysis were performed using a BD LSRFortessa™ Cell Analyzer System and FlowJo™ software. Data shown on this Technical Data Sheet are not batch specific.

      Product Notices

      1. Since applications vary, each investigator should titrate the reagent to obtain optimal results.
      2. 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.
      3. Please refer to www.bdbiosciences.com/us/s/resources for technical protocols.
      4. Sodium azide is a reversible inhibitor of oxidative metabolism; therefore, antibody preparations containing this preservative agent must not be used in cell cultures nor injected into animals. Sodium azide may be removed by washing stained cells or plate-bound antibody or dialyzing soluble antibody in sodium azide-free buffer. Since endotoxin may also affect the results of functional studies, we recommend the NA/LE (No Azide/Low Endotoxin) antibody format, if available, for in vitro and in vivo use.
      5. Please refer to http://regdocs.bd.com to access safety data sheets (SDS).

      C398.4A

      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.

      Purified
      Tissue culture supernatant is purified by either protein A/G or affinity purification methods. Both methods yield antibody in solution that is free of most other soluble proteins, lipids, etc. This format provides pure antibody that is suitable for a number of downstream applications including: secondary labeling for flow cytometry or microscopy, ELISA, Western blot, etc.
