* In our lab, we concentrate our lentivirus after production using PEG-precipitation. This increases the concentration 50-100x. '''Then, we "spinoculate" K562 cells with a small amount of virus in an eppendorf tube. Typically, this means putting 50,000 - 100,000 K562 cells in an eppendorf tube, adding 1-2 uL of lentivirus, adding polybrene to 4 ug/ml, and centrifuging for 30 min at 800 x g (at 32 C or room temperature).''' If your lentivirus is of good quality, this method gives very high infection rate (normally I get greater than 90%...close to 100) | * In our lab, we concentrate our lentivirus after production using PEG-precipitation.
