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).
Product Notices
- Since applications vary, each investigator should titrate the reagent to obtain optimal results.
- Human donor specific background has been observed in relation to the presence of anti-polyethylene glycol (PEG) antibodies, developed as a result of certain vaccines containing PEG, including some COVID-19 vaccines. We recommend use of BD Horizon Brilliant™ Stain Buffer in your experiments to help mitigate potential background.

- Researchers should determine the optimal concentration of this reagent for their individual applications.
- 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.
Companion Products
The 7.1 monoclonal antibody specifically recognizes Neural/Glial Antigen 2 (NG2) which is also known as Melanoma chondroitin sulfate proteoglycan (MCSP) and High molecular weight-melanoma associated antigen (HMW-MAA). This ~251 kDa transmembrane proteoglycan is encoded by CSPG4 (Chondroitin sulfate proteoglycan 4). Chondroitin Sulfate (NG2) is expressed by glial cells but not detected on normal marrow hematopoietic and peripheral blood cells. It is highly expressed by cells in some cancers including melanomas, leukemias, sarcomas and carcinomas. Chondroitin Sulfate (NG2) plays important roles in cellular proliferation, migration, and in oncogenic pathways involved in malignant transformation and metastases.
