What are lentiviral vectors?
Lentiviral vectors are tools used to deliver genetic material into cells, particularly useful for non-dividing cells.
How are lentiviral vectors produced?
They are produced by cotransfecting lentiviral transfer plasmids and helper plasmids into 293T cells.
What is the purpose of ultracentrifugation?
Ultracentrifugation is used to purify and concentrate the lentiviral vector supernatant.
How is the titer of the vector determined?
The titer can be determined using flow cytometry or real-time quantitative PCR.
What types of cells can be transduced?
The protocol demonstrates transduction in primary cultured neurons and astrocytes, but it can apply to other cell types as well.
What is the significance of immunostaining?
Immunostaining is used to assess transduction efficiency by visualizing target cells expressing the transgene.
