Preparation and Storage
推奨アッセイ手順
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).
Product Notices
- 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.
- Researchers should determine the optimal concentration of this reagent for their individual applications.

The APB5 monoclonal antibody specifically recognizes CD140b, the Platelet-Derived Growth Factor Receptor beta chain (PDGFRβ). CD140b is a single-pass type I transmembrane glycoprotein that contains an intracellular tyrosine kinase domain. This receptor is encoded by Pdgfrb and is widely expressed on cells within embryonic tissues and cells of mesenchymal origin in the adult mouse including fibroblasts and vascular smooth muscle cells. CD140b forms homodimers or heterodimeric receptor complexes with CD140a (PDGFRα) upon binding various dimeric Platelet-Derived Growth Factors (PDGF) isoforms that lead to receptor activation. Upon activation, CD140b is autophosphorylated at multiple tyrosine sites and, in turn, initiates several signaling cascades by binding and activation of cytoplasmic SH2 domain-containing signal transduction molecules, such as GRB2, Src, GAP, PI3 kinase, PLCγ, and NCK. These signaling pathways regulate cellular growth and proliferation, survival, differentiation, and migration involved in the development of embryonic tissues, blood vessel formation, wound healing, and in a range of diseases including fibrotic conditions, atherosclerosis, and malignancies.
