BV421 Mouse Anti-Human Siglec-6 (CD327)
BV421 Mouse Anti-Human Siglec-6 (CD327)
Two-color flow cytometric analysis of Siglec-6 (CD327) expression on peripheral blood lymphocytes. Peripheral blood mononuclear cells (PBMC) were costained with PE Mouse Anti-Human CD19 (Cat. No. 555413 or 561741) and either BD Horizon™ BV421 Mouse IgG2a, κ Isotype Control (Cat. No. 562439; Left Plot) or BD OptiBuild™ BV421 Mouse Anti-Human Siglec-6 (CD327) (Cat. No. 747915; Right Plot) at 0.25 μg/test. The pseudocolor dot plots showing the correlated expression of Siglec-6 (CD327) [or Ig Isotype control staining] versus CD19 were derived from gated events with the forward and side light-scatter characteristics of viable lymphocytes. Flow cytometry and data analysis were performed using a BD LSRFortessa™ X-20 Cell Analyzer System and FlowJo™ software. The above is qualification data only and does not represent a specific OptiBuild™ lot.

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 that minimize unconjugated dye and antibody.

Recommended Assay Procedures

BD™ CompBeads can be used as surrogates to assess fluorescence spillover (Compensation).  When fluorochrome conjugated antibodies are bound to 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 CompBead to ensure that BD Comp beads are appropriate for your specific cellular application.

For optimal and reproducible results, BD Horizon Brilliant Stain Buffer should be used anytime two or more BD Horizon Brilliant dyes 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. 563794/566349) or the BD Horizon Brilliant Stain Buffer Plus (Cat. No. 566385).

Product Notices

  1. 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.
  2. Researchers should determine the optimal concentration of this reagent for their individual applications.
  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.

767329

The 767329 monoclonal antibody specifically recognizes Sialic acid-binding Ig-like lectin 6 (Siglec-6) which is also known as Obesity-binding protein 1 (OB-BP1), CD33 antigen-like 1 (CD33L1), or CD327. Siglec-6 (CD327) is a type I transmembrane glycoprotein that is encoded by SIGLEC6 which belongs to the Sialic acid-binding Ig-like lectins (Siglecs) superfamily. Siglec-6 (CD327) has one N-terminal Ig-like V-set domain followed by two Ig-like C2-type domains in its extracellular region. Its intracellular region has an immunoreceptor tyrosine-based inhibitory motif (ITIM) as well as a signaling lymphocyte activating molecule (SLAM)-like motif that can serve as a docking site for  SAP (SLAM-associated protein). This I-type lectin can also exist in a soluble form of the extracellular region that lacks the transmembrane and cytoplasmic regions. Siglec-6 (CD327) is expressed on placental trophoblasts and B cells and at low levels on neutrophils. It specifically recognizes sialyl Tn-containing molecules and binds to leptin and is involved in cellular interactions and signaling.

The antibody was conjugated to BD Horizon BV421 which is part of the BD Horizon Brilliant™ Violet family of dyes. With an Ex Max near 407 nm and Em Max near 421 nm, BD Horizon BV421 can be excited by the violet laser (405 nm) and detected with a 450/50 nm filter. BD Horizon BV421 conjugates are very bright, often exhibiting a 10 fold improvement in brightness compared to Pacific BlueTM conjugates. Due to nearly identical excitation and emission properties but different spillover characteristics, BD Horizon BV421, Pacific Blue, and BD Horizon V450 cannot be used simultaneously.

BV421
The BD Horizon Brilliant Violet™ 421 (BV421) Dye is part of the BD Horizon Brilliant Violet™ family of dyes. This polymer-technology based dye has an excitation maximum (Ex Max) of 407-nm and an emission maximum (Em Max) at 423-nm. Driven by BD innovation, BV421 is designed to be excited by the violet laser (405-nm) and detected using an optical filter centered near 420-nm (e.g., a 431/28-nm or 450/50-nm bandpass filter). BV421 is an ideal alternative for V450 as it is approximately ten times brighter with less spillover into the BV510/V500 detector. Please ensure that your instrument’s configurations (lasers and optical filters) are appropriate for this dye.
