PE Mouse Anti-HuR
PE Mouse Anti-HuR
Two-parameter flow cytometric analysis of HuR expression in human peripheral blood mononuclear cell populations. Human PBMCs were fixed and permeabilized using the BD Pharmingen™ Transcription Factor Buffer Set (Cat. No. 562574/562725) followed by staining with either PE Mouse IgG1, κ Isotype Control (Cat. No. 559320; Left Plot) or PE Mouse Anti-HuR antibody (Cat. No. 566341; Right Plot) at 0.063 µg/test. Two-parameter flow cytometric contour plots showing the correlated expression of HuR (or Ig Isotype control staining) versus side light-scatter (SSC-A) signals were derived from gated events with the forward and side light-scattering characteristics of intact mononuclear leucocyte populations. Flow cytometric analysis was performed using a BD LSRFortessa™ Cell Analyzer System X-20. Data shown on this Technical Data Sheet are not lot specific.
PE Mouse Anti-HuR

Flow cytometric analysis of HuR expression in mouse spleen cells. C57BL/6 mouse splenic leucocytes were fixed and permeabilized using the BD Pharmingen™ Transcription Factor Buffer Set followed by staining with either PE Mouse IgG1, κ Isotype Control (dashed line histogram) or PE Mouse Anti-HuR antibody (solid line histogram) at 0.063 µg/test. The fluorescence histograms were derived from the gated events with the forward and side light-scattering characteristics of intact leucocytes. Flow cytometric analysis was performed using a BD LSRFortessa™ Cell Analyzer System. 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 with R-PE under optimum conditions, and unconjugated antibody and free PE were removed.

Product Notices

  1. Since applications vary, each investigator should titrate the reagent to obtain optimal results.
  2. An isotype control should be used at the same concentration as the antibody of interest.
  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.

3A2

The 3A2 monoclonal antibody specifically recognizes HuR (Human antigen R) which is encoded by ELAVL1 (ELAV like RNA binding protein 1). HuR belongs to the ELAVL (embryonic lethal, abnormal vision and Drosophila-like) family of proteins that includes HuB (ELAVL2), HuC (ELAVL3) and HuD (ELAVL4). These proteins contain three RNA recognition motifs that selectively bind AU rich elements (AREs) found in the 3' untranslated regions of messenger RNAs. Although predominantly located in the nucleus, HuR shuttles between the nucleus and cytoplasm. HuR stabilizes ARE-containing mRNAs, regulates RNA splicing, and can thus influence the outcome of gene expression. HuR is expressed by a variety of cell types including leucocytes, eg, T cells, B cells, and dendritic cells, whereas the other ELAVL family members are primarily expressed by neurons. HuR is involved in regulating cellular growth and differentiation, eg, through the stabilization and shuttling of mRNAs including those encoding transcription factors, proto-oncogenes, costimulatory receptors, growth factors, cytokines, chemokines, and inflammatory mediators. Abnormal expression of HuR has been linked to a number of diseases, for example, overexpressed HuR levels have been detected in certain tumor cells. The 3A2 antibody crossreacts with mouse HuR as well as with human HuB and HuD, but not with HuC.

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.
