Bikard Lab - EcoWG1: E. coli Genome-wide Inhibition Library
(Pooled Library #131625)
This library contains ~20,000 unique guide RNAs targeting the non-template strand of every open reading frame and annotated small RNAs in the chromosome of E. coli MG1655. The library contains an average of 5 targets per gene and was made by cloning a pool of guide RNAs oligos into psgRNA (#114005) (ori: ColE1) by Gibson assembly.
This library can be used with SpdCas9 to perform pooled CRISPRi screens as shown ( Cui et al., 2018 ; Rousset et al. 2018). Screens can be performed using strain LC-E75 (#115925). The psgRNA_EcoWG1 Library has the same backbone as the psgRNA Library, but the gRNAs in this library have have higher inhibition efficiency.

This library is delivered as suspended DNA in a microcentrifuge tube on blue ice. The tube's contents will not necessarily be frozen. For best results, minimize freeze-thaws.
NOTE: 100 ng of the library can be electroporated into cells for an experiment. Sufficient sample is provided for several experiments and amplification of the library.
The depositing lab recommends using their code for analyzing Illumina sequencing results.
For additional information on use of this library, please see Rousset et al., 2018.
These pooled libraries were created by your colleagues. Please acknowledge the Principal Investigator, cite the article in which the plasmids were described, and include Addgene in the Materials and Methods of your future publications.
