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. This will 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).

The MAC2-158 monoclonal antibody (also known as Clone MAC 2-158) specifically binds to human CD163. CD163 is also known as Scavenger receptor cysteine-rich type 1 protein M130 (M130), SCARI1 (SR-I1), or Hemoglobin scavenger receptor (HbSR). CD163 is an ~130 kDa type I transmembrane glycoprotein comprised of an extracellular domain with nine cysteine-rich (SRCR) scavenger receptor class B domains followed by a transmembrane region and a short cytoplasmic tail. CD163 is expressed on most peripheral blood monocytes, tissue macrophages, and a subset of dendritic cells. CD163 serves as a high affinity receptor for hemoglobin and haptoglobin and mediates endocytosis of hemoglobin and haptoglobin complexes by macrophages. This scavenging function may protect tissues from hemoglobin-mediated oxidative damage and contribute to the uptake and recycling of iron. CD163 can also reportedly bind to (TNF-a)-like weak inducer of the apoptosis (TWEAK) protein and some pathogenic bacteria. A cleaved, soluble form of CD163 can reportedly play an anti-inflammatory role and serve as a marker for macrophage activation in inflammatory responses. High-affinity binding of the MAC2-158 antibody to CD163 is reportedly unaffected by extracellular calcium levels. This clone can be used to measure CD163 expression in freshly drawn whole blood samples stabilized with commonly used anticoagulants, eg, EDTA, citrate or heparin.
