ScienCell's GeneQuery™ Human Microglial Sensome qPCR Array (GQH-MGS) facilitates gene expression profiling of 88 key genes involved in how microglia perceive their environment.  Microglia are considered to be “the resident macrophages of the CNS,” so how they sense their environment is integral to maintaining homeostatic functions in the brain during pathogen invasion, injury, or degeneration.  The genes included in this particular array focus on genes with unique differential expression in aging.  Examples of how included genes may be grouped according to their function are shown below:

• Classical priming: PTGS2, TNF, CXCL10
• Alternative priming: SPP1, MARCO, CXCR4, CLEC7A, CD163
• Chemokine receptors: PTAFR, CMKLR1, GPR77, C5AR1, CCR5
• Purinergic receptors: TMEM173, P2RY1, P2RY12, GPR34, ADORA3
• Aging: TREM2, TLR8, SCARA3, IFITM3, AGER

GeneQuery™ qPCR array kits are qPCR ready in a 96-well plate format, with each well containing one primer set that recognizes and efficiently amplifies a specific 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 the target gene, unless otherwise noted; and (iii) only one gene is amplified. Each primer set has been validated by qPCR with melt curve analysis and gel electrophoresis.
