RAPID COMMUNICATION kat : A High - Efficiency Retroviral Transduction System for Primary Human T Lymphocytes
We describe a novel retroviral packaging system in which high titer amphotropic retrovirus was produced without the need to generate stable producer clones. kat expression vectors, which produce high levels of retroviral vector transcripts and retroviral packaging functions, were transfected into 293 cells followed by virus harvest 48 hours posttransfection. Viral titers as high as 3.8 proviral...

متن کاملPackaging of endogenous retroviral sequences in retroviral vectors produced by murine and human packaging cells.
Interaction of retrovirus vectors and endogenous retroviruses present in packaging cell lines and target cells may result in unwanted events, such as the formation of recombinant viruses and the mobilization of therapeutic vectors. Using sensitive reverse transcriptase PCR assays, we investigated human and murine gene therapy packaging cell lines for incorporation of endogenous retrovirus trans...
متن کاملExpression of Recombinant Factor IX Using the Transient Gene Expression Technique
Background: Pilot and large-scale production of recombinant proteins requires the presence of stable clones capable of producing large quantities of recombinant proteins. Not only the process of selecting stable clones is time consuming, but also the continuous culturing of clones in large-scale production may cause loss of incoming plasmid and recombinant genes. Thus, considering the advanceme...
متن کاملUse of enhanced green fluorescent protein to optimize and quantitate infection of target cells with recombinant retroviruses.
Recombinant retroviral vectors are useful tools for gene transfer in both gene therapy and research applications. An enhanced form of green fluorescent protein has been incorporated into recombinant retroviruses as a marker to follow infected cells. In this paper, we extended the use of the fluorescent reporter to quantify protein expression using such analytical tools as fluorescent microscopy...
