Depositor Comments

shRNA to human CD44 (should target all isoforms). Subcloned via NdeI-BamHI frm pLKO1.Puro. This insert replaced identical sequence present in pRRL-EGFP and added the shRNA sequence


Please note that the shRNA oligo present in this plasmid is referred to as shCD44-3 in the associated publication.
