CD4 Mouse anti-Human, V500, Clone: RPA-T4, BD

Description

• The RPA-T4 clone reacts with CD4, a 59kDa single-chain transmembrane glycoprotein [receptor for human immunodeficiency virus (HIV)] present on T-helper/inducer cell populations
• This antibody binds to the D1 domain (CDR1 and CDR3 epitopes) of the CD4 antigen and reacts with approximately 80% of thymocytes and 45% of peripheral blood lymphocytes
• CD4 is also present in low density on peripheral blood monocytes
• RPA-T4 is capable of blocking HIV-1, gp120, and inhibits syncytium formation
• The antibody is conjugated to BD Horizon™ V500, which has been developed for use in multicolor flow cytometry experiments and is available exclusively from BD Biosciences
• It is excited by the Violet laser with an Ex max of 415 nm and Em Max at 500nm
• BD Horizon V500 conjugates emit at a similar wavelength to Amcyan yet exhibit reduced spillover into the FITC channel

• When compensating dyes in this spectral range (such as Horizon™ V500 and AmCyan), the most accurate compensation can be obtained using single stained cellular controls
• Due to spectral differences between cells and beads in this channel, using BD CompBeads can result in spillover errors for V500 and AmCyan reagents
• Therefore, the use of BD CompBeads or BD CompBeads Plus to determine spillover values for these reagents is not recommended
• Different V500 reagents (e.g
• CD4 vs
• CD45) can have slightly different fluorescence spillover therefore, it may also be necessary to use clone specific compensation controls when using these reagents
