Ultracentrifugation protocols are tedious, time consuming, and result in only partially purified lentivirus. Our ViraBind™ PLUS Lentivirus Concentration & Purification Kits provide a much simpler, faster way to obtain high titer lentivirus with greater purity. Each prep can process up to 50 mL of lentivirus supernatant in our standard kit and 500 mL in our Mega kit.
