What is a Pseudotyped vector?
In pseudotyping, you produce viral vectors using viral envelope proteins from another virus to either restrict or broaden the host cell range (tropism). Pseudotyping is only done on enveloped viruses such as lentivirus, retrovirus, and rabies virus.
What was the purpose of the VSV G pseudotyped lentivirus in the cellular infections?
The VSV-G protein has been the most popular for pseudotyping the envelope proteins of lentiviral vectors. VSV-G binds LDL-Receptor family members, allowing these viruses to infect a wide range of cell types of many distinct host species, including rodent and human cells [15].
How long can lentivirus be stored at?
Storage of Lentivirus Virus can be stored at 4°C for a short time (less than a week) before using after reception. Since Lentiviruses are sensitive to freeze-thawing and the titer drops with repeated freeze-thawing, aliquot viral stock should be stored at – 80°C freezer immediately upon arrival for long-term usage.
What is pseudotyped virus?
Pseudotyped viruses (PVs), replication-defective viral particles formed with a structural and enzymatic core from one virus and the envelope glycoprotein of another, are a flexible option with little associated risk.
What is a Pseudotyped virus?
What is VSV G virus?
Vesicular stomatitis virus G (VSV G) protein is a typical type III viral fusion protein. To study the mechanism of VSV G protein mediated membrane fusion, we set up a cell-cell fusion system in which cells are marked by different fluorescent proteins.
How long is AAV stable at 4 degrees?
However if the virus is repeated freeze-and-thaw, it will cause significant decrease of titer. For short-term storage, AAV is stable at 4? C for up to almost 2-3 weeks. 6.
What is pseudotyped AAV?
An AAV pseudotyping strategy is one that replaces the capsid of AAV2 with the capsid of another AAV serotype. For example, an AAV2/5 vector has the genome of AAV2 but has the capsid of AAV5. This change in the AAV serotype capsid could potentially result in a unique tropism for each pseudotyped vector.
