      PE Mouse Anti-Human Neutrophil Elastase
      PE Mouse Anti-Human Neutrophil Elastase
      Flow cytometric analysis of Human Neutrophil Elastase expression in Human peripheral blood granulocytes and tumor cell lines. Human peripheral blood granulocytes (Left Panel) prepared by density gradient centrifugation and cells from the Human Jurkat (Acute T cell leukemia, ATCC TIB-152; Middle Panel) and Human U-937 (Histiocytic Lymphoma, ATCC CRL-1593, Right Panel) were fixed with BD Cytofix™ Fixation Buffer (Cat. No. 554655), washed and then permeabilized with  BD Perm/Wash™ Buffer (Cat. No. 554723). The cells were then stained in BD Perm/Wash™ Buffer with either PE Mouse IgG1, κ Isotype Control (Cat. No. 554680; Dotted Line Histograms) or PE Mouse Anti-Human Neutrophil Elastase antibody (Cat. No. 568908;568909; Solid Lines) at 0.5 µg/test. The fluorescence histograms showing Neutrophil Elastase expression (or Ig Isotype control staining) were derived from gated events with the light-scatter characteristics of intact cells. Flow cytometry and data analysis were performed using a BD LSRFortessa™ X20 Cell Analyzer System and FlowJo™ software. Data shown on this Technical Data Sheet are not lot specific.

      Preparation And Storage

      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 and unconjugated antibody and free dye were removed.

      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 cell and BD® CompBeads to ensure that BD® CompBeads are appropriate for your specific cellular application.

      Product Notices

      1. Please refer to www.bdbiosciences.com/us/s/resources for technical protocols.
      2. 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.
      3. Since applications vary, each investigator should titrate the reagent to obtain optimal results.
      4. For fluorochrome spectra and suitable instrument settings, please refer to our Multicolor Flow Cytometry web page at www.bdbiosciences.com/colors.
      5. An isotype control should be used at the same concentration as the antibody of interest.
      6. Please refer to http://regdocs.bd.com to access safety data sheets (SDS).

      NP57

      The NP57 monoclonal antibody specifically recognizes human Neutrophil Elastase (NE) which is also known as Human leukocyte elastase (HLE), Granulocyte-derived Elastase (GE), or PMN Elastase (PMN-E). Neutrophil Elastase is a major serine proteinase encoded by ELANE (Elastase, neutrophil expressed) that belongs to the elastase subfamily within the peptidase S1 family. Neutrophil Elastase is predominantly present in the azurophilic granules (primary granules) of neutrophils and monocytes. When released outside of these effector cells, it can act to hydrolyze a variety of extracellular matrix substrates including elastin, fibronectin, collagen, and proteoglycans. Elastase activity in normally controlled by serine proteinase inhibitors. Neutrophil Elastase can regulate the functions of NK cells, monocytes, and granulocytes, eg, by inhibiting C5a-dependent enzyme release and chemotaxis by neutrophils. It is also capable of killing bacteria such as E. coli and degrading virulence factors from bacteria such as Yersinia, Shigella, and Salmonella. Dysregulated expression or defects in this enzyme are associated with some inflammatory and degenerative diseases including rheumatoid arthritis, emphysema, chronic obstructive pulmonary disease, and cystic fibrosis as well as neutropenias.

      PE
      R-Phycoerythrin (PE), is part of the BD family of Phycobiliprotein dyes. This fluorochrome is a multimeric fluorescent phycobiliprotein with excitation maximum (Ex Max) of 496 nm and 566 nm and an emission maximum (Em Max) at 576 nm. PE is designed to be excited by the Blue (488 nm), Green (532 nm) and Yellow-Green (561 nm) lasers and detected using an optical filter centered near 575 nm (e.g., a 575/26-nm bandpass filter). As PE is excited by multiple lasers, this can result in cross-laser excitation and fluorescence spillover on instruments with various combinations of Blue, Green, and Yellow-Green lasers. Please ensure that your instrument’s configurations (lasers and optical filters) are appropriate for this dye.
