The 217-170 monoclonal antibody specifically recognizes mouse IgD of Igh-C[b] haplotype (eg, C57BL/6, C57BL/10, SJL). It does not react with IgD of Igh-C[a] or related haplotypes (eg, BALB/c, AKR, CBA, C3H/He, C58, DBA/1, DBA/2, NZB, PL, RIII), or Igh-C[e] haplotype (eg, A). 217-170 antibody is effective for detection of cell-surface Ig by immunofluorescent staining with flow cytometric analysis. It has not been shown to stimulate B-cell proliferation.
The antibody was conjugated to BD Horizon™ BV650 which is part of the BD Horizon Brilliant™ Violet family of dyes. This dye is a tandem fluorochrome of BD Horizon BV421 with an Ex Max of 405-nm and an acceptor dye with an Em Max at 650-nm. BD Horizon BV650 can be excited by the violet laser and detected in a filter used to detect APC-like dyes (eg, 660/20-nm filter). Due to the excitation and emission characteristics of the acceptor dye, there will be spillover into the APC and Alexa Fluor® 700 detectors. However, the spillover can be corrected through compensation as with any other dye combination.
