Description
The SA14-2 monoclonal antibody specifically recognizes mouse CD14. CD14 is an ~55-kDa glycosyl phosphatidyl inositol (GPI)-linked cell-surface glycoprotein that is encoded by Cd14. CD14 is expressed on macrophages, granulocytes, dendritic cells, hepatocytes, and Kupffer cells. CD14 is also expressed in a soluble form (sCD14). CD14 is a leucine-rich repeat-containing pattern recognition receptor which serves as coreceptor for bacterial lipopolysaccharide (LPS) from gram-negative bacteria. CD14 forms a complex with lipopolysaccharide (LPS), an endotoxin from gram-negative bacteria, with LPS-binding protein (LBP, a plasma protein). The LPS-LPB-CD14 complex can then associate with TLR4-MD-2 which transduces intracellular signals. In this way, CD14 can play roles in innate cellular anti-bacterial immune and inflammatory responses, such as through the stimulation of cellular IL-1 and TNF production, and in extreme cases, the development of endotoxic shock.
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).
Store undiluted at 4°C and protected from prolonged exposure to light. Do not freeze. The monoclonal antibody was purified from tissue culture supernatant or ascites by affinity chromatography. The antibody was conjugated to the dye under optimum conditions that minimize unconjugated dye and antibody.
