Preparation And Storage
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
- 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.
- Researchers should determine the optimal concentration of this reagent for their individual applications.
- An isotype control should be used at the same concentration as the antibody of interest.
- 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.

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.
