Learn how screening empowers discovery
How to use siRNA, shRNA, microRNA and CRISPR libraries
What can screening do for me?
Functional genomic screening uses libraries of reagents that can interrogate tens, hundreds or thousands of genes to determine which are the most important to the biology under study. Screening can reveal the genes that are critical to cancer biology pathways, find drug targets and many other important biological applications.
What kind of biological reagents can be used for screening?
The reagents fall into two categories:
- microRNA inhibitors
- CRISPR-Cas9 guide RNA (crRNA, sgRNA)
- gain of function
- microRNA Mimics
- cDNAs / ORFs
All of these can be had in library formats that include collections of genes involved in cellular pathways, gene families and even whole genome scale to individually test every possible gene. Also, custom libraries can be created according to a customer’s own gene list.
Is screening difficult?
There are many different types of screening strategies. The choice of the best approach depends on the particular biological question, the phenotypic readout, and the infrastructural resources that are available to the investigator.
To explain some of the important aspects of setting up a screening experimental plan, we have prepared a Screening Applications Page to explain key consideration for developing and executing a screening strategy. In it, you will learn:
- considerations for functional genomics studies by high-throughput library screening
- types and formats of screening libraries
- plasmid libraries
- lentiviral libraries
- pooled lentiviral libraries
- high-throughput functional genomics screening workflow - general considerations
- collecting phenotypic screening data
- assay development and validation
- siRNA screening
- pooled lentiviral shRNA library screening
- hit stratification
- confirmation of results
