Lentiviral constructs expressing sgRNA sequences may be transduced into cells with Cas9 or dCas9 variants to knock out, knock down (CRISPRi), or activate (CRISPRa) gene expression in vivo or in vitro.
Cellecta offers a range of constitutive and inducible lentiviral vector backbones with different selection and fluorescent markers for cloning and expression of sgRNA.
If you can’t find a suitable expression construct, Cellecta may be able to make it as a custom construct.
