I;ve been trying to reporgram cells using lentiviruses.. my 293 cells usually turn about 80% green (GFP) after 48 hours.. but when i use the virus to infect cells, i do not get ips, or the ips that I get is usually fake colonies.
Another problem that I am facing is the iPS generated lifts off the surface of the dishes, so I am unable to use the cut and paste method to passage my cells.. anyone encountered this before?
