      Preparation And Storage

      Store undiluted at 4°C and protected from prolonged exposure to light. Do not freeze. The monoclonal antibody was purified from tissue culture supernatant or ascites by affinity chromatography. The antibody was conjugated with biotin under optimum conditions, and unreacted biotin was removed.

      Product Notices

      1. Since applications vary, each investigator should titrate the reagent to obtain optimal results.
      2. An isotype control should be used at the same concentration as the antibody of interest.
      3. 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.
      4. For fluorochrome spectra and suitable instrument settings, please refer to our Multicolor Flow Cytometry web page at www.bdbiosciences.com/colors.
      5. Please refer to www.bdbiosciences.com/us/s/resources for technical protocols.

      16A

      The 16A monoclonal antibody specifically recognizes an exon B-dependent epitope of CD45 lycoprotein, which is found at high density on peripheral B cells, T cytotoxic/suppressor cells, a subset of T helper cells, and most thymocytes, and at low density on macrophages and dendritic cells. CD45RB expression appears to decrease as T lymphocytes progress from naive to memory cells. In addition, subpopulations of CD4+ T cells which express high and low levels of CD45RB have different cytokine secretion profiles and mediate distinct immunological functions. CD25+  D4+ regulatory T (Treg) lymphocytes which control intestinal inflammation and autoimmunity express low levels of  CD45RB.  CD45 is a member of the Protein Tyrosine Phosphatase (PTP) family; its intracellular (COOH-terminal) region contains two PTP catalytic domains, and the extracellular region is highly variable due to alternative splicing of exons (designated A, B, and C, respectively) as well as differing levels of glycosylation. The CD45 isoforms detected in the mouse are cell type-, maturation-, and activation state-specific. The CD45 isoforms play complex roles in T-cell and B-cell antigen receptor signal transduction.

      Biotin
      Biotin is a ubiquitous co-factor (also known as Vitamin B7) that has many properties that make it extremely useful for molecular biology. Biotin has an extremely high affinity for the Avidin family of proteins (Kd = 10-15 M), making it the perfect tool to link two molecules. Biotin labeled antibodies can be combined with any number of Avidin-conjugated probes in order to customize an assay to a particular need. This is especially useful in the case of magnetic cell separation using streptavidin/magnetic bead conjugates, or in the case of flow cytometry using streptavidin/fluorophore conjugates.
