Anti Rat Macrophage / Dendritic Cells Monoclonal Antibody


This anti-rat macrophage/dendritic cells monoclonal antibody, RM-4, was produced by using a homogenate of silica-induced lung granulomas of rat as immunogen. Immunohistochemistry demonstrated that RM-4 is specific for rat macrophages and dendritic cell populations in various organs and tissues.
In both cryostat sections and formalin-fixed paraffin sections, this antibody recognizes the antigen, of which molecular weight is 46kDa, presenting on the membrane of endosomes and lysosomes in macrophages and dendrictic cells.
Thus, this antibody is very useful for not only in discriminating macrophage/dendritic cells from various cell populations but also in identifying endosomes and lysosomes.

Package Size 50μg (200μL / viaL)
Format Mouse monoclonal antibody 0.25mg/mL
Buffer Block Ace as a stabilizer, containing 0.1% Proclin as a bacteriostat
Storage Store below 20°C
Once thawed, store at 4°C. Repeated freeze-thaw cycles should be avoided
Clone No. RM-4
Subclass IgG1
Purification method The spleen cells from BALB/c mouse, immunized with homogenate of silica-induced lung granuloma of rat, were fused to myeloma NS-1 cells. The screening of the hybridoma cells was performed on cryostat sections of rat spleens. The hybridoma cell line (RM-4) with positive reaction was grown in ascitic fluid of BALB/c mouse, from which the antibody was purified by Protein G affinity chromatography.
Working dilution for immunohistochemistry: 10μg/mL on frozen sections and paraffin sections.
