The CD21 antibody, clone B-ly4, is derived from the hybridization of mouse myeloma cells with spleen cells from immunized mice.

The CD21 antibody specifically binds to a 145-kilodalton (kDa) glycosylated type I integral membrane protein. The CD21 antigen is also known as complement receptor type 2 (CR2), C3d receptor, and Epstein-Barr virus receptor (EBV-R).

BD Horizon™ V450 Dye is part of the BD Horizon™ violet family of dyes. This is a small organic fluorochrome with an excitation maximum (Ex Max) at 405-nm and an emission maximum (Em Max) at 450-nm. BD Horizon™ V450, driven by BD innovation, is designed to be excited by the violet laser (405 nm) and detected using an optical filter centered near 450-nm (e.g., a 450/50-nm bandpass filter). The dye can be excited by the UV (355-nm) laser resulting in cross-laser excitation and spillover. Please ensure that your instrument’s configurations (lasers and optical filters) are appropriate for this dye.
