10 best practices for a good transduction efficiency

  1. 1- Know your cells.
  2. 2- Check the quality of your lentiviral vector batch.
  3. 3- Optimize the transgene expression cassette.
  4. 4- Make sure your titer is in TU/ml.
  5. 5- Follow storage and thawing requirements.
  6. 6- Monitor cells sensitivity towards transduction enhancers.

How does viral transduction work?

Transduction happens through either the lytic cycle or the lysogenic cycle. When bacteriophages (viruses that infect bacteria) that are lytic infect bacterial cells, they harness the replicational, transcriptional, and translation machinery of the host bacterial cell to make new viral particles (virions).

Do you need polybrene for transduction?

It is definitely possible to transduce your cells without the presence of polybrene or any other polycation.

What is the process of transduction?

Transduction is the process by which a virus transfers genetic material from one bacterium to another. Later, when one of these bacteriophages infects a new host cell, this piece of bacterial DNA may be incorporated into the genome of the new host. There are two types of transduction: generalized and specialized.

What is an example of transduction?

Technically speaking, transduction is the process of converting one form of energy into another. For example, your ears receive energy (sound waves) and transduce (or convert) this energy into neural messages that make their way to your brain and are processed as sounds. …

How is transduction used?

Transduction is a common tool used by scientists to introduce different DNA sequences of interest into a bacterial cell or a host’s genome. Scientists also use transduction to introduce foreign DNA into eukaryotic cells, like mammalian cell lines. This can be done with lentiviral and Adeno Associated Viruses (AAV).

What happens during transduction?

Transduction: When the signaling molecule binds the receptor it changes the receptor protein in some way. Each relay molecule in the signal transduction pathway changes the next molecule in the pathway. 3. Response: Finally, the signal triggers a specific cellular response.

Can a BMDM cell be transduced with a lentivirus?

Has anyone succeeded in transduction the RAW or BMDM cells with lentivirus (PLKO.1) without puromycin selection? The BMDM selection could be a little bit difficult if I need large scale of cells for sequencing analysis for example, I suppose if I increase the dosage of the virus I will manage to get nice knocking down without puromycin selection.

What does the Moi mean for lentiviral transduction?

The MOI describes the number of virus particles needed to infect one cell. However, the probability of a cell infection is subject to the statistical Poisson distribution. For example, a MOI of 10 signifies that 10 virus particles are needed for one cell to be infected efficiently. In principle, the MOI for lentiviral particles ranges from 1 to 30.

What are the host cells for lentiviral transduction?

Lentiviral vectors have a broad host cell range that includes cell types such as neurons, lymphocytes, and macrophages. Previously, retrovirus vectors could not be used for these cell types. Moreover, lentiviral vectors have. Figure 1: Simplified illustration of the lentiviral transduction mechanism.

Are there any tricks for lentiviral transduction to macrophages?

What would be the best way to transfect macrophages/dendritic cells in vitro with plasmids for reporter assay or flourescent imaging with a good transfection efficiency without causing too much toxcitity that can be used for immortal/primary cell lines? Are there any  tricks for lentiviral transduction to macrophage sych as J774.1 cells (ATCC)?
