A Fourth Generation Lentiviral Vector: Simplifying Genomic Gymnastics

Lentiviral Vector

A retroviral vector system based on the human immunodeficiency virus (HIV) was developed that, in contrast to a murine leukemia virus-based counterpart, transduced heterologous sequences into HeLa cells and rat fibroblasts blocked in the cell cycle, as well as into human primary macrophages. Additionally, the HIV vector could mediate stable in vivo gene transfer into terminally differentiated n...

A Modified lentiviral vector construction system

Objective: To develop a lentiviral vector system, which can be used to co-express multiple genes of interest, such as siRNAs cassettes, reporter gene and resistant gene simultaneously and to facilitate to titrate lentiviral vector stock with TCID50 method. Method: Synthesis new multiple cloning sites(MCS)to replace the original MCS of pLKO-1-puro and produced an intermediate plasmid pLKO-1-puro...

Gene Regulatable Lentiviral Vector System

Optimal assembly plan generation: a simplifying approach

Abstract: The main difficulty in the overall process of optimal assembly plan generation is the great number of different ways to assemble a product (typically thousands of solutions). This problem confines the application of most existing automated planning methods to products composed of only a limited number of components. The presented method of assembly plan generation belongs to the appro...

Generation of a lentiviral vector producer cell clone for human Wiskott-Aldrich syndrome gene therapy

We have developed a producer cell line that generates lentiviral vector particles of high titer. The vector encodes the Wiskott-Aldrich syndrome (WAS) protein. An insulator element has been added to the long terminal repeats of the integrated vector to limit proto-oncogene activation. The vector provides high-level, stable expression of WAS protein in transduced murine and human hematopoietic c...
