FISHing with locked nucleic acids (LNA): evaluation of different LNA/DNA mixmers

Mol Cell Probes. 2003 Aug;17(4):165-9. doi: 10.1016/s0890-8508(03)00048-3.


Locked Nucleic Acids (LNA) constitute a novel class of DNA analogues that have an exceptionally high affinity towards complementary DNA and RNA. Using human classical satellite-2 repeat sequence clusters as targets, we demonstrate that LNA/DNA mixmers oligonucleotides are excellent probes for FISH combining high binding affinity with short hybridization time and even with the ability to hybridize without prior thermal denaturation of the template.
