A Protocol for Multiple Gene Knockout in Mouse Small Intestinal Organoids Using a CRISPR-concatemer

18.9K
This protocol describes the steps for cloning multiple single guide RNAs into one guide RNA concatemer vector, which is of particular use in creating multi-gene knockouts using CRISPR/Cas9 technology. The generation of double knockouts in intestinal organoids is shown as a possible application of this...

Generation of Genetically Modified Mice through the Microinjection of Oocytes

21.6K
The microinjection of mouse oocytes is commonly used for both classic transgenesis (i.e., the random integration of transgenes) and CRISPR-mediated gene targeting. This protocol reviews the latest developments in microinjection, with a particular emphasis on quality control and genotyping...

DNA Vector-based RNA Interference to Study Gene Function in Cancer13:10

DNA Vector-based RNA Interference to Study Gene Function in Cancer

21.0K
RNA interference (RNAi) possesses many advantages over gene knockout and has been broadly used as a tool in gene functional studies. The invention of DNA vector-based RNAi technology has made long term and inducible gene knockdown possible, and also increased the feasibility of gene silencing in...

Quantitative and Automated High-throughput Genome-wide RNAi Screens in C. elegans10:58

Quantitative and Automated High-throughput Genome-wide RNAi Screens in C. elegans

18.2K
We describe a protocol using C. elegans and RNAi feeding libraries that allows automated measurement of multiple parameters such as fluorescence, size and opacity of individual worms in a population. We give one example of a screen to identify genes involved in anti-fungal innate immunity in C.
