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 BD Horizon BV480 under optimal conditions that minimize unconjugated dye and antibody.

Recommended Assay Procedures

For optimal and reproducible results, BD Horizon Brilliant Stain Buffer should be used anytime two or more BD Horizon Brilliant dyes (including BD OptiBuild Brilliant reagents) are used in the same experiment.  Fluorescent dye interactions may cause staining artifacts which may affect data interpretation.  The BD Horizon Brilliant Stain Buffer was designed to minimize these interactions.  More information can be found in the Technical Data Sheet of the BD Horizon Brilliant Stain Buffer (Cat. No. 563794).

Product Notices

  1. This antibody was developed for use in flow cytometry.
  2. The production process underwent stringent testing and validation to assure that it generates a high-quality conjugate with consistent performance and specific binding activity. However, verification testing has not been performed on all conjugate lots.
  3. Researchers should determine the optimal concentration of this reagent for their individual applications.
  4. An isotype control should be used at the same concentration as the antibody of interest.
  5. 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.
  6. For fluorochrome spectra and suitable instrument settings, please refer to our Multicolor Flow Cytometry web page at
  7. Please refer to for technical protocols.
  8. BD Horizon Brilliant Stain Buffer is covered by one or more of the following US patents: 8,110,673; 8,158,444; 8,575,303; 8,354,239.

The 8A-1 monoclonal antibody specifically binds to CD148, which is also known as Protein tyrosine phosphatase receptor type J (Ptprj), Receptor-type tyrosine-protein phosphatase eta (R-PTP-eta, PTPη), or Density-enhanced phosphatase-1 (DEP-1). CD148 is a receptor-like tyrosine phosphatase that plays important roles in regulating cell growth, proliferation, differentiation, adhesion, and migration. It is expressed on a wide variety of cell types including epithelial cells, endothelial cells, and fibroblasts. For cells of hemopoietic origin, it is variably expressed on macrophages, neutrophils, dendritic cells, and on developing and mature B cells. CD148 is expressed on platelets and can regulate platelet activation. Although expressed at low levels on thymocytes and mature T cells, its expression is upregulated upon T cell receptor (TCR)-mediated stimulation and may play a role in regulating TCR signaling. CD148, along with CD45, are critical protein tyrosine phosphatases for regulating Src family kinase signaling networks in immune cells.

The antibody was conjugated to BD Horizon™ BV480 which is part of the BD Horizon Brilliant™ Violet family of dyes. With an Ex Max of 436-nm and Em Max at 478-nm, BD Horizon BV480 can be excited by the violet laser and detected in the BD Horizon BV510 (525/40-nm) filter set.  BV480 has less spillover into the BV605 detector and, in general, is brighter than BV510.

The BD Horizon Brilliant Violet™ 480 (BV480) Dye is part of the BD Horizon Brilliant Violet™ family of dyes. This polymer-technology fluorochrome has an excitation maximum (Ex Max) of 440-nm and an emission maximum (Em Max) of 479-nm. Driven by BD innovation, BV480 is designed to be excited by the violet laser (405-nm) and detected using an optical filter centered near 480-nm (e.g., a 525/50 bandpass filter). The increased fluorescence intensity of BV480 and narrower emission spectra, make it a good alternative for BV510 or V500. Due to its excitation profile, BV480 will also has less cross-laser excitation with the UV laser, resulting in less spillover into UV channels compared to BV510. Please ensure that your instrument’s configurations (lasers and optical filters) are appropriate for this dye.
