PuRetro™ Lentivirus and Retrovirus Purification Kit (2 U)
|G171||2 Purification Sets|
Both recombinant retrovirus and lentivirus are widely used in the transduction of a varity of target cells and can be produced by transient transfection, from which viral supernatant can be collected and used for target cell transduction. The titer of viral supernatant by transient transfection is approximately 106 cfu (colony forming unit)/ml, which is sufficient Purification Experimental Flow Chart for the generation of most stable cell lines in vitro. However, there are applications that require higher purity and titers. These applications include experiments demanding higher gene transduction efficiency and in vivo gene delivery. In addition, crude viral supernatants are not suitable for in vivo administration due to various contaminants contained in cell culture supernatant. Thus, the viral supernatant needs to be further concentrated and purified before use. Traditionally, both recombinant retrovirus and lentivirus have been concentrated via ultracentrifugation. Although the method works well, it requires specific ultracentrifugation equipment and it is technically demanding. In addition, the total viral supernatant volume is limited to the size of ultracentrifugation tubes. Reports have also stated that the ultracentrifugation process has some detrimental physical effects on the recombinant virus. Due to limitations on the existing technique, there is great necessity for a quick and efficient method to purify and concentrate recombinant retrovirus and lentivirus. Scientists at ABM Inc. have had years of experience with Ion-Exchange-based filter membranes and have successfully developed PuRetro™, the most effective retroviral and lentiviral purification method based on this technology.
