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.
For optimal and reproducible results, BD Horizon Brilliant™ Stain Buffer should be used anytime BD Horizon Brilliant dyes are used in a multicolor flow cytometry panel. Fluorescent dye interactions may cause staining artifacts which may affect data interpretation. The BD Horizon Brilliant Stain Buffer was designed to minimize these interactions. When BD Horizon Brilliant Stain Buffer is used in in the multicolor panel, it should also be used in the corresponding compensation controls for all dyes to achieve the most accurate compensation. For the most accurate compensation, compensation controls created with either cells or beads should be exposed to BD Horizon Brilliant Stain Buffer for the same length of time as the corresponding multicolor panel. 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 HP6002 monoclonal antibody specifically recognizes the subclass of human Immunoglobulin G (IgG) known as IgG2. After human IgG1, human IgG2 is the second most abundant of the four subclasses of IgG found in human serum followed by IgG3 and IgG4. IgG2 is comprised of two identical heavy chains encoded by IGHG2, and two light chains, either Igκ or Igλ, linked by disulfide bonds. The HP6002 antibody binds to the CH2 domain of the IgG2 heavy chain and does not crossreact with other immunoglobulin heavy chain (IgH) subclasses. IgG2 is normally expressed by plasmablasts, plasma cells, and memory B cells as well as by some myeloma or plasmacytoma cells. HP6002 binds to soluble human IgG2, cytophilic IgG2 attached to cells through its Fc region, or human IgG2 antibodies specifically bound to antigens. IgG2 can cross the placenta and disseminate throughout extravascular fluids throughout the body. Human IgG2 serves multiple functions with the transmembrane form serving as an antigen receptor for B lymphocytes and secreted soluble forms participating in various effector functions including antibody-dependent neutralization of toxins or infection by microbes and complement fixation.
