      PE Mouse IgG2a, κ Isotype Control
      PE Mouse IgG2a, κ Isotype Control
      Expression of human MIP-1α by stimulated CD14+ human monocytes. Human PBMC were stimulated for 6 hours with LPS (100 ng/ml final concentration) in the presence of GolgiStop™ (2 µM final concentration; Cat. No. 554724). The PBMC were harvested, stained with FITC-mouse anti-human CD14 monoclonal antibody (FITC-M5E2, Cat. No. 555397), fixed permeabilized, and subsequently stained with either PE-anti-human MIP-1α (Cat. No. 554730, left panel), or PE-mouse IgG2a, κ (Cat. No. 559319; middle panel), by following the Pharmingen staining protocols. The data reflect gating on monocytes, based on forward and scattered light signals. The quadrant markers for the bivariate dot plot were set based on autofluorescence controls (right panel).

      Preparation And Storage

      The monoclonal antibody was purified from tissue culture supernatant or ascites by affinity chromatography. The antibody was conjugated with R-PE under optimum conditions, and unconjugated antibody and free PE were removed. Store undiluted at 4°C and protected from prolonged exposure to light. Do not freeze.

      Recommended Assay Procedures

      Immunofluorescent Staining and Flow Cytometric Analysis: The FITC- and PE-conjugated G155-178 immunoglobulins (Cat. No. 554647; No. 554648) are suitable mouse IgG2a isotype controls for assessing the level of background staining on paraformaldehyde fixed/saponin-permeabilized rat or human cells for flow cytometric analysis. Use at comparable  concentrations to antibody of interest (middle panel). For specific methodology, please visit our website, www.bdbiosciences.com and go to the protocols section or the chapter on intracellular staining in the Immune Function Handbook. The intracellular cytokine staining technique and use of blocking controls are described in detail by C. Prussin and D. Metcalfe.

      Product Notices

      1. Since applications vary, each investigator should titrate the reagent to obtain optimal results.
      2. Please refer to www.bdbiosciences.com/us/s/resources for technical protocols.
      3. 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.

      G155-178

      The G155-178 clone has an unknown specificity. Trinitrophenol (TNP), the immunogen, is a hapten not expressed on human, mouse, rat or non-human primate cells. In the absence of specific binding, this antibody may bind non-specifically to immunoglobulin Fc receptors. The immunoglobulin secreted by the G155-178 hybridoma was selected as a mouse IgG2a, κ isotype control following screening for low background binding on a variety of mouse and human tissues.

      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.
