Mouse CRISPR Proximal Poly(A) Site Knockout Library
(Pooled Library #190744)

• Purpose:

  The mouse pKO library targets proximal poly(A) signal sequences in genes identified to be differentially polyadenylated in the mouse B16-F10 melanoma system. Growth controls include gene knockouts of core essential or tumor suppressor genes and a large number of control paired-guide RNAs targeting poly(A) sites in genes that are not expressed in B16-F10 melanoma cells. Deleting the proximal poly(A) site forces use of more distal sites.

• Vector Backbone:

  lentiGuide-Puro (Plasmid #52963) - does not express Cas9
