ScienCell's GeneQuery™ Human Microglial Polarization Markers qPCR Array Kit (GQH-MPM) is designed to facilitate gene expression profiling of 40 marker genes involved in microglial polarization, which has important implications for regulating innate immunological functions. When microglia are stimulated, two potential phenotypes can be observed: pro-inflammatory M1 microglia and anti-inflammatory M2 microglia. The M1 phenotype acts to protect tissues against invading pathogens by releasing cytokines and revoking acute inflammation, while the M2 phenotype acts to restore tissue homeostasis and stimulate tissue repair. Brief examples of how included genes may be grouped according to their functions are shown below:     

• M1 phenotype marker: TNF, FCGR2A, FCGR2B, FCGR2C, FCGR3A, FCGR3B, CD86, IL1B, NOS2, IL6
• M2 phenotype marker: MRC1, IL4, IL10, TGFB1, IL1R1, SOCS3, ARG1, IL13, SPHK1
• Activation/resting markers: CD80, CLEC5A, HEXB, HLA-DQA1, HLA-DQB1, HLA-DRA, HLA-DRB1, IRF8, ITGAM, MYB, PTGES, RUNX1, TLR3, TLR4
• Additional microglia markers: ADGRE1, AIF1, CD40, CD68, EDA, ITGAM, ITGAX, PTPRC

GeneQuery™ qPCR array kits are qPCR ready in a 96-well plate format, with each well containing one primer set that can specifically recognize and efficiently amplify a target gene's cDNA. The carefully designed primers ensure that: (i) the optimal annealing temperature in qPCR analysis is 65°C (with 2 mM Mg2+, and no DMSO); (ii) the primer set recognizes all known transcript variants of target gene, unless otherwise indicated; and (iii) only one gene is amplified. Each primer set has been validated by qPCR with melt curve analysis, and gel electrophoresis.
