LNPs are liposome-like structures especially geared towards encapsulating a broad variety of nucleic acids (RNA and DNA); and as such, they are the most popular non-viral gene delivery system. Exelead develops and manufactures LNPs to encapsulate different types of genetic payloads including siRNA, mRNA and saRNA.
