NLS (PKKKRKV)
Based on 3 publication(s) in Google Scholar
NLS (PKKKRKV) is a nuclear localization signal (NLS) derived from the SV40 large T antigen, which mediates the binding of karyophilic proteins to importin α. NLS (PKKKRKV) serves as a method to enhance nuclear entry in the field of gene transfer research.

Descripciòn
In Vitro
Pre-incubation of NLS (20:1 mass ratio; 72 h) with pmaxGFP plasmid prior to the preparation of LNP-M formulations significantly reduces the transfection efficiency of LNP-M/pGFP in 293T cells, resulting in a final GFP-positive cell proportion of 17.7%[3].
Pre-incubation of NLS (80:1 mass ratio; 24 h post-transfection) with DSPC prior to the preparation of LNP-M formulations significantly enhances the transfection efficiency of LNP-M/pGFP in 293T cells, resulting in a GFP-positive cell ratio of 94.6% while increasing MFI[3].
