Lentivirus Purification Mini Kit, 10. The ViraTrapTM lentivirus mini purification kit is designed for fast and efficient purification of recombinant lentiviruses from lentiviral-transfected cell culture supernatant. Up to 3x10^10 viral particles can be purified from cell culture media of 1 to 2 x T75 flasks. The viruses are first pelleted from viral supernatant and then further purified and concentrated through a purification column and a desalting/concentration unit. Each column can be regenerated for purifying the same lentivirus. For optimized viral binding and recovery, each column can be regenerated only once.
