Lentiviral technology has proven to be a powerful tool to express exogenous genes in dividing and non-dividing cells. Currently, most protocols for generating high-titer lentivirus require ultracentrifugation, which can be an instrumental barrier for routine operations in a laboratory. In this study, the effect of relative centrifugal force (RCF) on the concentration efficiency of the lentiviru...
A South African isolate of ovine lentivirus was shown to cause a mild immunosuppression in sheep, reflected by a reduced delayed hypersensitivity reaction. This effect, measured in terms of skin swelling after intradermal inoculation with tuberculin, showed a positive linear relationship with the latency period before the appearance of jaagsiekte symptoms in animals co-infected with JSRV, as we...
Gene transduction and expression efficiencies among several type cell lines were compared by using vesicular stomatitis virus-glycoprotein (VSV-G) pseudotyped human immunodeficiency virus type-1 (HIV-1) based lentivirus vector. Large discrepancies of the efficiencies were shown among them. B lymphocytes showed high susceptibility of the gene transduction and expression, while other cell lines m...
We present a new modular concept to construct organizational models for transcriptional regulatory DNA units. The method requires a training set of at least 10 sequences and a simple initial model (e.g. two characteristic transcription factor binding sites). The final model is generated by computer analysis directly from the sequences. 20 Lentivirus long terminal repeats (LTRs) and an initial m...
Objective: To construct a recombinant lentivirus vector which carries SD rat transducer of regulated CREB activity-1(TORC1) gene and examine its ability to express the TORC1 gene in vitro. Methods: The coding sequence of SD rat TORC1 gene was amplified using PCR and cloned into pGC-FU vector. 293T cells were transfected using Lipofectamine 2000 and packaged for the recombinant lentivirus partic...
