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 BV605 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 1A5 monoclonal antibody specifically recognizes Sialic acid binding Ig-like lectin 5 (Siglec-5) which is also known as CD170, CD33 antigen-like 2 (CD33L2) and Obesity binding protein-2 (OBBP2). CD170 is a type I transmembrane glycoprotein that forms a ~140 kDa dimer on the cell surface. CD170 is encoded by SIGLEC5 which belongs to the SIGLEC (sialic acid binding Ig-like lectin) family within the immunoglobulin superfamily. The extracellular region of CD170 consists of an N-terminal V-set Ig-like domain, which contains the sialic acid binding site, followed by 3 C2-set Ig like domains, a transmembrane region and a cytoplasmic tail containing 2 immunoreceptor tyrosine-based inhibitory motifs (ITIMs) which regulate cellular signaling. CD170 bind to alpha-2,3- and alpha-2,6-linked sialic acid glycoproteins and glycolipids and to glycophorin A. It is highly expressed on neutrophils and expressed at lower levels on monocytes, macrophages, dendritic cells, and some lymphocytes. CD170 is an adhesion molecule that may function in regulating cellular activation and in sialic-acid dependent binding to cells.

This antibody is conjugated to BD Horizon™ BV605 which is part of the BD Horizon Brilliant™ Violet family of dyes. With an Ex Max of 407-nm and Em Max of 602-nm, BD Horizon BV605 can be excited by a violet laser and detected with a standard 610/20-nm filter set. BD Horizon BV605 is a tandem fluorochrome of BD Horizon BV421 and an acceptor dye with an Em max at 605-nm. Due to the excitation of the acceptor dye by the green (532 nm) and yellow-green (561 nm) lasers, there will be significant spillover into the PE and BD Horizon PE-CF594 detectors off the green or yellow-green lasers. BD Horizon BV605 conjugates are very bright, often exhibiting brightness equivalent to PE conjugates and can be used as a third color off of the violet laser.

The BD Horizon Brilliant Violet™ 605 (BV605) dye is part of the BD Horizon Brilliant Violet™ family of dyes. This tandem fluorochrome is comprised of a BV421 donor with an excitation maximum (Ex Max) of 407-nm and an acceptor dye with an emission maximum (Em Max) at 605-nm. BV605, driven by BD innovation, is designed to be excited by the violet laser (405-nm) and detected using an optical filter centered near 610-nm (e.g., a 610/20-nm bandpass filter). The acceptor dye can be excited by the yellow-green (561-nm) laser resulting in cross-laser excitation and fluorescence spillover. Please ensure that your instrument’s configurations (lasers and optical filters) are appropriate for this dye.
