Macrophages commonly exist in two distinct subsets: classically activated macrophages (M1) and alternatively activated macrophages (M2). M1 macrophages can facilitate immunity to remove foreign pathogens and tumor cells, mediate tissue damage, and impair wound healing and tissue regeneration. A better understanding of the molecular pathways and transcriptional programs associated with M1 macrophage subtypes, as well as reliable markers, is necessary for further progress in the M1 macrophage field. Creative Biolabs is well-equipped and versed in the identification of M1 macrophages based on our clients’ requirements. We are glad to serve our global clients with professionalism and expertise in M1 macrophage identification.
