Preparation And Storage
Recommended Assay Procedures
BD® CompBeads can be used as surrogates to assess fluorescence spillover (compensation). When fluorochrome conjugated antibodies are bound to BD® CompBeads, they have spectral properties very similar to cells. However, for some fluorochromes there can be small differences in spectral emissions compared to cells, resulting in spillover values that differ when compared to biological controls. It is strongly recommended that when using a reagent for the first time, users compare the spillover on cells and BD® CompBeads to ensure that BD® CompBeads are appropriate for your specific cellular application.
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 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).

The 2F3 monoclonal antibody specifically recognizes CD369 which is also known as Dectin-1 (Dendritic cell-associated C-type lectin 1) or BGR (Beta-glucan receptor). CD369 is a ~ 43 kDa type II transmembrane C-type lectin that is encoded by Clec7a (C-type lectin domain family 7, member a). The extracellular portion of CD369 (Clec7a) contains a C-terminal stalk with a carbohydrate recognition domain (CRD) that is followed by a transmembrane segment, and an ITAM-containing cytoplasmic tail. This protein is predominantly expressed on monocytes/macrophages, neutrophils and some dendritic cell populations and at a lower level on a sub-population of T cells. CD369 (Clec7a) binds to beta-glucan polymers and functions as a pattern recognition receptor (PRR) in innate immune response to fungal and bacterial pathogens. CD369 mediated signaling may play a role in leucocyte responses, including phagocytosis or enhanced cytokine production. In mice, two functionally different full-length and stalkless isoforms have been characterized. Both isoforms vary in their ability to recognize zymosan and mediate cellular responses upon zymosan recognition.
