Constitutively Expressed gRNA targeting mRFP
This Constitutively Expressed gRNA targeting mRFP is a no-BioBrick-scars assembly of the constitutive promoter BBa_J23100, DNA sequence of a gRNA that targets mRFP reporter and a reliable terminator BBa_B0015. This gRNA sequence comes from the following literature: QI, LEI S., LARSON, MATTHEW H., GILBERT, LUKE A., DOUDNA, JENNIFER A., WEISSMAN, JONATHAN S., ARKIN, ADAM P. & LIM, WENDELL A. 2013. Repurposing CRISPR as an RNA-Guided Platform for Sequence-Specific Control of Gene Expression. Cell, 152, 1173-1183.
