The L307 monoclonal antibody specifically binds to B7/BB1, a 60 kDa transmembrane glycoprotein that was clustered as CD80 in the Fifth International Workshop on Human Leukocyte Differentiation Antigens. CD80, a member of the Ig supergene family, is expressed on activated B cells, T cells, macrophages, and dendritic cells. It is the ligand for two molecules expressed on T cells, CD28 and CD152 (CTLA-4). CD80 is also expressed on activated CD4-positive and CD8-positive T cells, appearing late after activation suggesting that activated T cells may be capable of autocrine costimulation via the CD28 activation pathway. The binding of CD28 by anti-CD28 or by CD80 results in T-cell activation and a signal for IL-2 production.
This antibody was conjugated to BD Horizon APC-R700, which has been developed exclusively by BD Biosciences as a better alternative to Alexa Fluor® 700. APC-R700 excites and emits at similar wavelengths to Alexa Fluor® 700 yet exhibits significantly improved brightness. This dye can be excited by the red laser and detected with the same filter set as Alexa Fluor® (eg, 730/45-nm filter).

APC-R700
The BD Horizon™ APC-R700 (APC-R700) Dye is a part of the BD APC red family of dyes. This tandem fluorochrome is comprised of an Allophycocyanin (APC) dye donor that has excitation maximum (Ex Max) of 651-nm and an acceptor dye, R700, with an emission maximum (Em Max) at 706-nm. APC-R700, driven by BD innovation, is designed to be excited by the red (627–640-nm) laser and detected using an optical filter centered near 710-nm (e.g., a 720/40-nm bandpass filter). APC-R700 is a brighter alternative to Alexa Fluor™ 700. Please ensure that your instrument’s configurations (lasers and optical filters) are appropriate for this dye.

Flow cytometric analysis of CD80 expression on human Raji cells. Cells from the human Raji (Burkitt’s B cell lymphoma, ATCC CCL-86) cell line were stained with either BD Horizon™ APC-R700 Mouse IgG1, κ Isotype Control (Cat. No. 564974; dashed line histogram) or BD Horizon APC-R700 Mouse Anti-Human CD80 antibody (Cat. No. 565157; solid line histogram). The fluorescence histograms were derived from gated events with the forward and side light-scatter characteristics of viable cells. Flow cytometric analysis was performed using a BD™ LSR II Flow Cytometer System.
