Preparation And Storage
Recommended Assay Procedures
For optimal and reproducible results, BD Horizon Brilliant Stain Buffer should be used anytime two or more BD Horizon Brilliant dyes (including BD OptiBuild Brilliant reagents) 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).
Product Notices
- This antibody was developed for use in flow cytometry.
- 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 433H monoclonal antibody specifically binds to C-C chemokine receptor type 8 (CC-CKR-8 or CCR8) which is also known as CD198, GPRCY6, CY6, CKRL1, CMKBR8, CMKBRL2, or TER1. CCR8 (CD198) is a seven-transmembrane, G-protein-coupled, glycoprotein receptor that belongs to the beta chemokine receptor family. CCR8 is expressed on monocytes, macrophages, eosinophils, Langerhans cells, thymocytes, and vascular smooth muscle cells. It is preferentially expressed on some T cell subsets including skin resident memory T cells, type 2 T-helper (Th2-like) cells, and T regulatory cells. CCR8 is a receptor for the chemokine C-C motif chemokine 1 (CCL1), also known as SCYA1 or I-309, and plays a role in regulating monocyte and T cell chemotaxis and thymocyte apoptosis. CCR8 may play a role in lung T cell recruitment in asthma and can serve as an alternative coreceptor to CD4 for HIV-1 infection. The 433H antibody reportedly neutralized the chemotactic response of cultured T cells to CCL1.
The antibody was conjugated to BD Horizon™ BV510 which is part of the BD Horizon Brilliant™ Violet family of dyes. With an Ex Max of 405-nm and Em Max at 510-nm, BD Horizon BV510 can be excited by the violet laser and detected in the BD Horizon V500 (525/50-nm) filter set. BD Horizon BV510 conjugates are useful for the detection of dim markers off the violet laser.
