Description

Mouse Monoclonal Antibody

The LN2 monoclonal antibody specifically recognizes CD74, the cell surface MHC class II-associated invariant chain molecule (41, 35, 33 kDa). CD74 is moderately expressed on B cells, and weakly on monocytes and macrophages. Other reactive cells include Langerhans cells, dendritic cells, a subset of activated T cells and thymic epithelium. The LN2 monoclonal antibody labels a nuclear membrane protein of follicular center and mantle zone B cells and a cytoplasmic protein of cells which bind HLA class II antibodies. CD74 is postulated to play a role in antigen processing and presentation through intracellular transport and expression of class II molecules on the cell surface. This antibody is suitable for staining formalin-fixed, paraffin-embedded tissue sections without citrate pretreatment.

The antibody was conjugated to BD Horizon™ BV421 which is part of the BD Horizon Brilliant™ Violet family of dyes. With an Ex Max of 407nm and Em Max at 421nm, BD Horizon BV421 can be excited by the violet laser and detected in the standard Pacific Blue™ filter set (eg, 450/50nm filter). BD Horizon BV421 conjugates are very bright, often exhibiting a 10 fold improvement in brightness compared to Pacific Blue conjugates. BV421 is a polymer-based dye excited by the violet laser and is one of the brightest fluorochromes offered by BD Biosciences. Conjugates are typically 10 times brighter than Pacific Blue™ conjugates and are often as bright as or brighter than PE conjugates. Due to nearly identical excitation and emission properties but different spillover characteristics, BD Horizon BV421, Pacific Blue™, and BD Horizon™ V450 cannot be used simultaneously.
