Solved by a verified expert:A gene expression company is working on a viral infection site in the brain of monkeys to identify gene expression changes in that area. To do that they need a pure sample of infected cells from that site and then perform analysis on that. They also want to get the control sample from the same animal.• Clearly delineate a method that can be used for isolation of a pure population of infected cells from that brain site• Where/Which area will you isolate the control cells from• How will you identify genes that are specifically expressed in the viral infected area
