PE Mouse Anti-Human CD170
PE Mouse Anti-Human CD170

Multiparameter flow cytometric analysis of CD170 expression on human peripheral blood leucocyte populations. Human blood was stained with either Mouse IgG1, κ Isotype Control (Cat No. 559320, Left Plot) or PE Mouse Anti-Human CD170 antibody (Cat No. 566777; Right Plot). Erythrocytes were lysed with BD Pharm Lyse™ Lysing Buffer (Cat. No. 555899). The flow cytometric contour plot showing the correlated expression of CD170 (or Ig Isotype control staining) versus side light-scatter (SSC-A) signals was derived from gated events with the forward and side-light scatter characteristics of viable leucocyte populations. Flow cytometry and data analysis were performed using a BD FACSCantoTM II Flow Cytometer System and FlowJo™ software.

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. Please refer to www.bdbiosciences.com/us/s/resources for technical protocols.
  2. 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.
  3. For fluorochrome spectra and suitable instrument settings, please refer to our Multicolor Flow Cytometry web page at www.bdbiosciences.com/colors.
  4. This reagent has been pre-diluted for use at the recommended Volume per Test. We typically use 1 × 10^6 cells in a 100-µl experimental sample (a test).
  5. An isotype control should be used at the same concentration as the antibody of interest.

1A5/CD170

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.

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.
