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).
For optimal results, it is recommended to perform two washes after staining with antibodies. Cells may be prepared, stained with antibodies and washed twice with wash buffer per established protocols for immunofluorescent staining prior to acquisition on a flow cytometer. Performing fewer than the recommended wash steps may lead to increased spread of the negative population.
Product Notices
- 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.
- An isotype control should be used at the same concentration as the antibody of interest.
- 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.

The ASC-8 monoclonal antibody specifically recognizes CD104 which is also known as Integrin beta 4 (Integrin β4 or β4 Integrin). Integrins mediate important intercellular and cell-extracellular matrix interactions which are essential for cellular adhesion and migration as well as for regulating cellular growth and survival. CD104 (Integrin β4) is an ~205 kDa single-pass type I transmembrane glycoprotein that is encoded by ITGB4 (Integrin subunit beta 4). CD104 (Integrin β4) noncovalently associates with CD49f (Integrin α6 chain) to form the Integrin α6/β4 (CD49f/CD104) complex. CD104 (Integrin β4) is expressed on basal epithelial cells, Schwann cells, and some endothelial cells and tumor cells. The CD49f/CD104 complex serves as an adhesion receptor that binds to laminins and keratin filaments. It is a component of epidermal hemidesmosomes that facilitate the stable adhesion of basal epithelial cells to the underlying basement membrane.
