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 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
- Researchers should determine the optimal concentration of this reagent for their individual applications.
- 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.
- Please refer to www.bdbiosciences.com/us/s/resources for technical protocols.
- 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.

- Since applications vary, each investigator should titrate the reagent to obtain optimal results.
- 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.

The 837535 monoclonal antibody specifically recognizes Sialic acid-binding Ig-like lectin 8 (Siglec-8) which is also known as Sialoadhesin family member 2 (SAF-2). Siglec-8 is a single-pass, type I transmembrane glycoprotein that is encoded by SIGLEC8 which belongs to the Sialic acid-binding Ig-like lectins (Siglecs) superfamily. Siglec-8 has an Ig-like V-set domain followed by two Ig-like C-type domains in its extracellular region. Its intracellular region contains an immunoreceptor tyrosine-based inhibitory motif (ITIM) and an immunoreceptor tyrosine-based switch motif (ITSM) which might contribute to inhibitory signal transduction upon engagement of this receptor. A short form of Siglec-8 that results from alternative splicing and which lacks most of the intracellular domain has also been identified. Siglec-8 is expressed on eosinophils and mast cells, and weakly on basophils. Siglec-8 appears to serve as an adhesion molecule which mediates cell-cell interactions through its binding to 6' sulfated sialyl Lewis X carbohydrate structures. Siglec-8 seems to be involved in signal transduction since engagement of Siglec-8 can induce apoptosis in eosinophils or inhibit mast cell degranulation.
