PE Mouse IgG2b, κ Isotype Control
PE Mouse IgG2b, κ Isotype Control
Expression of human IL-8 by stimulated CD14+ human monocytes. Human PBMC were stimulated for 6 hours with LPS (1.0 µg/ml final concentration) in the presence of GolgiStop™ (2 µM final concentration; Cat. No. 554724). The PBMC were harvested, stained with 0.25 µg of FITC-mouse anti-human CD14 monoclonal antibody (FITC-M5E2, Cat. No. 555397), fixed, permeabilized, and subsequently stained with either 0.125 µg of PE-anti-human IL-8 (Cat. No. 554720; left panel), or 0.125 µg of PE-mouse IgG2b (Cat. No. 555058; middle panel), following BD PharMingen staining protocol. The data reflect gating on monocytes, based on forward and side 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 PE- and FITC-conjugated 27-35 immunoglobulin (Cat. No. 555057; 555058) are suitable mouse IgG2b 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 (e.g., ≤ 0.5 µg mAb/1 million cells) (see image, right panel). For specific methodology, please visit the protocols section or chapter on intracellular staining in the Immune Function Handbook, both of which are posted on our web site, www.bdbiosciences.com. 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. For fluorochrome spectra and suitable instrument settings, please refer to our Multicolor Flow Cytometry web page at www.bdbiosciences.com/colors.
  4. 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.

27-35

This mouse IgG2b, κ isotype control is a monoclonal antibody, clone 27-35, that is specific for the dansyl (5-[dimethylamino] naphthalene-1-sulfonyl) hapten. The dansyl (DNS) hapten is not expressed on human cells or human cell lines. The 27-35 immunoglobulin was selected as an isotype control following testing that demonstrated low background staining 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.
