mRFP expression in neurones and glia in dorsal vagal and hypoglossal motor nuclei
Representative images are shown for the experimental conditions evaluated. mRFP-expressing cells transduced with either AVV- or LVV-CMV-mRFP are shown in the left hand panels; IR for NeuN or GFAP in […]
WHAT ARE SOME DIFFERENT WAYS TO TITER LENTIVIRUS?
Functional titer is defined as the number of functional vector particles required to infect a cell, present in a volume. There are several methods for measuring titer. Some are more […]
PRACTICAL APPLICATIONS AND LIMITATIONS OF LENTIVIRAL VECTOR
Applications of lentivirus vectors include stable gene transfer for gene delivery in gene and cell therapy. This includes using RNA interference technology to block the expression of specific genes. Along […]
WHAT IS PSEUDOTYPING of LENTIVIRUS?
In HIV, pseudotyping is used to change the tropism of the virion. In other words, pseudotyping changes the way the Lentivector targets a specific cell for infection. In wild type […]
WHAT MAKES LENTIVIRUS SO SPECIAL?
Though there are several virus delivery systems available today for gene therapy, lentivirus is considered one of the best methods. Several features make lentivirus preferable especially the ability to infect […]
