Puromycin Trending Applications: shRNA Lentiviral Particles Transduction
Puromycin continues to be applied for genomic purposes. In this protocol, puromycin is utilized in lentiviral transduction in shRNA particles. DAY 1 Plate target cells in a 12-well plate 24 hours prior to viral infection. Add 1 ml of complete optimal medium (with serum and antibiotics) and incubate cells overnight. The cells should be approximately 50% confluent on the day... -
