Lentiviral Library

Updated May 13, 2024

Lentiviral library refers to a collection of lentiviral vectors that collectively encode a diverse set of genetic elements including genes, shRNAs (short hairpin RNAs), or CRISPR/Cas9 guide RNAs. These libraries offer researchers the opportunity to systematically interrogating gene function and regulatory networks on a genome-wide scale. Researchers can perform large scale functional genomics studies with high throughput and scalability.

How Is A Lentiviral Library Constructed?

Lentiviral libraries are typically generated by cloning individual genetic elements (such as those listed above) into lentiviral vector backbones, which are then packaged into lentiviral particles for delivery into target cells. Each lentiviral vector within the library carries a different genetic element, allowing researchers to introduce a diverse range of genetic perturbations into a population of cells.

There are many different types of libraries available for researchers and are chosen based on their research application. Our team has assembled this reference table that summarizes the different types of lentiviral libraries and their research goals:

Type Of Lentiviral LibraryLibrary ComponentsResearch Goals
cDNA LibrariesThese libraries consist of lentiviral vectors encoding complementary DNA sequences corresponding to genes of interest.Used to overexpress genes or gene variants in target cells for functional studies or screening experiments.
shRNA LibrariesThese libraries consist of small RNA molecules that can silence gene expression by triggering the degradation of target mRNA.Used for loss-of-function screens to identify genes involved in biological processes or disease phenotypes.
CRISPR/Cas9 LibrariesThese libraries consist of lentivirus vectors encoding guide RNAs (gRNAs) that target specific genomic loci for editing by the CRISPR/Cas9 system.Used for high throughput genome wide knock out or activation (knock in) screens to identify genes essential for cellular processes or disease states.
cDNA ORF LibrariesThese libraries consist of lentiviral vectors encoding open reading frames (ORFs) of genes.Used for allowing for the overexpression of full-length proteins or protein domains in target cells
