The MMRI-7 monoclonal antibody specifically recognizes CD205 which is also known as DEC-205, Lymphocyte antigen 75 (Ly-75), or C-type lectin domain family 13 member B (CLEC13B). CD205 is a ~205 kDa type I transmembrane glycoprotein with C-type lectin external domains. DEC-205 is expressed on myeloid and plasmacytoid dendritic cells, thymic epithelial cells, and at lower levels on monocytes, T cells, B cells, and natural killer (NK) cells. DEC-205 likely functions as an endocytic receptor and is involved in antigen uptake and processing.
The antibody was conjugated to BD Horizon™ BB700, which is part of the BD Horizon Brilliant™ Blue family of dyes. It is a polymer-based tandem dye developed exclusively by BD Biosciences. With an excitation max of 485 nm and an emission max of 693 nm, BD Horizon BB700 can be excited by the 488 nm laser and detected in a standard PerCP-Cy™5.5 set (eg, 695/40-nm filter). This dye provides a much brighter alternative to PerCP-Cy5.5 with less cross laser excitation off the 405 nm and 355 nm lasers.
