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 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).

- 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.
- Since applications vary, each investigator should titrate the reagent to obtain optimal results.
- The production process underwent stringent testing and validation to assure that it generates a high-quality conjugate with consistent performance and specific binding activity. However, verification testing has not been performed on all conjugate lots.

The BB13-1044 monoclonal antibody specifically recognizes Vascular endothelial growth factor receptor 2 (VEGFR-2) which is also known as CD309 and Fetal liver kinase 1 (FLK-1). This protein receptor tyrosine kinase is an ~230 kDa single pass type I transmembrane glycoprotein that is encoded by KDR (Kinase insert domain receptor). It is variably expressed by mesodermal and endothelial cells in embryonic tissues and by vascular endothelial cells, megakaryocytes, platelets, retinal progenitors, and smooth muscle cells in normal adult or tumor tissues. The N-terminal extracellular region of CD309 (VEGFR-2) consists of seven IgC2-like domains which are followed by a single transmembrane region and a C-terminal intracellular tyrosine kinase. The first three extracellular domains mediate ligand binding whereas the remaining four are involved in receptor dimerization. CD309 (VEGFR-2) functions as a receptor for several Vascular endothelial growth factor (VEGF) isoforms. Following receptor dimerization upon ligand binding, CD309 (VEGFR-2) autophosphorylates and stimulates the proliferation and migration of endothelial and other cell types.
