R718 Mouse Anti-Human Siglec-9 (CD329)
R718 Mouse Anti-Human Siglec-9 (CD329)
Multiparameter flow cytometric analysis of Siglec-9 (CD329) expression on Human peripheral blood leucocyte populations. Human whole blood was first treated with BD Pharm Lyse™ Lysing Buffer (Cat. No. 555899) to lyse erythrocytes, washed, and then preincubated with BD Pharmingen™ Human BD Fc Block™ (Cat. No. 564219/564220). The leucocytes were then stained with either BD Horizon™ R718 Mouse IgG1, κ Isotype Control (Cat. No. 566928; Left Plot) or BD Horizon™ R718 Mouse Anti-Human Siglec-9 (CD329) antibody (Cat. No. 569484/569485; Right Plot). The bivariate pseudocolor density plot showing the correlated expression of Siglec-9 (CD329) [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 leucocytes. Flow cytometry and data analysis were performed using a BD LSRFortessa™ X-20 Cell Analyzer 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 to the dye under optimum conditions and unreacted dye was removed.

Recommended Assay Procedures

BD® CompBeads can be used as surrogates to assess fluorescence spillover (compensation). When fluorochrome conjugated antibodies are bound to BD® CompBeads, they have spectral properties very similar to cells. However, for some fluorochromes there can be small differences in spectral emissions compared to cells, resulting in spillover values that differ when compared to biological controls. It is strongly recommended that when using a reagent for the first time, users compare the spillover on cells and BD® CompBeads to ensure that BD® CompBeads are appropriate for your specific cellular application.

Product Notices

  1. Please refer to www.bdbiosciences.com/us/s/resources for technical protocols.
  2. 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).
  3. An isotype control should be used at the same concentration as the antibody of interest.
  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.

  6. Human donor specific background has been observed in relation to the presence of anti-polyethylene glycol (PEG) antibodies, developed as a result of certain vaccines containing PEG, including some COVID-19 vaccines. We recommend use of BD Horizon Brilliant™ Stain Buffer in your experiments to help mitigate potential background.

K8

The K8 monoclonal antibody specifically recognizes Sialic acid-binding Ig-like lectin 9 (Siglec-9) which is also known as CD329. Siglec-9 (CD329) is a single-pass type I transmembrane glycoprotein that is encoded by SIGLEC9 which belongs to the I-type lectins within the Ig superfamily. This lectin is comprised of an N-terminal extracellular region that contains an IgV domain, which binds sialic acid, followed by two Ig-like C2-type domains, a transmembrane region, and an intracellular domain with an immunoreceptor tyrosine-based inhibitory motif (ITIM) and an ITIM-like motif . It is highly expressed on monocytes, neutrophils, and expressed at lower levels on a proportion of NK cells, B cells and T cells. Siglec-9 (CD329) may play roles in the regulation of T cell and NK cell responses and neutrophil apoptosis.

R718
The BD Horizon™ Red 718 (R718) Dye is part of the BD red family of dyes. It is a small organic fluorochrome with an excitation maximum (Ex Max) at 695-nm and an emission maximum (Em Max) at 718-nm. Driven by BD innovation, R718 is designed to be excited by the red laser (627–640-nm) and detected using an optical filter centered near 720-nm (e.g., a 720/40-nm bandpass filter). R718 is a brighter alternative to Alexa Fluor™ 700. R718 is also a bright small molecule alternative to APC-R700 with lower spread into the APC detector. Please ensure that your instrument’s configurations (lasers and optical filters) are appropriate for this dye.
