Abstract
Provided are compositions and methods that permit a hybrid nucleic acid-peptide molecule to enter a cell and when specifically activated within the cell, the molecule anneals to endogenous cellular RNA and permits the isolation of the RNA.
Claims7
A hybrid nucleic acid-peptide molecule comprising:
- a) a first, second, and third oligomer, wherein the first oligomer is linked to the second oligomer through a first photocleavable linker and the second oligomer is linked to the third oligomer through a second photocleavable linker, wherein the first, second, and third oligomers are arranged in a caged hairpin conformation
- wherein the second oligomer comprises a poly-A nucleic acid sequence, comprising at least 7 consecutive adenosines, that is complementary to a first nucleic acid sequence of the first oligomer, such that the first oligomer is hybridized to the second oligomer, and
- wherein the third oligomer comprises a poly-A nucleic acid sequence, comprising at least 7 consecutive adenosines, that is complementary to a second nucleic acid sequence of the first oligomer, such that the first oligomer is hybridized to the third oligomer;
- b) a label for isolating nucleic acids, wherein the label is linked to the first oligomer;
- c) a peptide moiety comprising a cell penetrating peptide (CPP).
