Description
The 2D5 monoclonal antibody specifically binds to human Regulated upon Activation, Normal T cells Expressed and Secreted (RANTES). RANTES belongs to the C-C family of chemokines and is also known as CCL5. RANTES is produced by activated macrophages, CD8+ T cells, platelets, fibroblasts, epithelial cells and some tumor cells. RANTES is a chemoattractant and response modifier for a variety of cells including memory T cells, NK cells, dendritic cells, monocytes, eosinophils, basophils, and mast cells. RANTES binds to and transduces intracellular signals through several cell surface chemokine receptors including CCR1, CCR3, CCR4, and CCR5. RANTES can reportedly inhibit the interaction between certain HIV viruses and CCR5 and thus suppress viral infection in vitro.
The antibody was conjugated to BD Horizon BV421 which is part of the BD Horizon Brilliant™ Violet family of dyes. With an Ex Max of 407-nm and Em Max at 421-nm, BD Horizon BV421 can be excited by the violet laser and detected in the standard Pacific Blue™ filter set (eg, 450/50-nm filter). BD Horizon BV421 conjugates are very bright, often exhibiting a 10 fold improvement in brightness compared to Pacific Blue conjugates.

BV421 is a polymer-based dye excited by the violet laser and is one of the brightest fluorochromes offered by BD Biosciences. Conjugates are typically 10 times brighter than Pacific Blue™ conjugates and are often as bright as or brighter than PE 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.

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 with BD Horizon BV421 under optimum conditions, and unconjugated antibody and free BD Horizon BV421 were removed.
Product Notices
- This reagent has been pre-diluted for use at the recommended Volume per Test. We typically use 1 × 10^6 cells in a 100-µl experimental sample (a test).
- An isotype control should be used at the same concentration as the antibody of interest.
- Source of all serum proteins is from USDA inspected abattoirs located in the United States.
- 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.
