New methodologies for site-specifically radiolabeling proteins with the PET isotope [18F] are required to generate high quality radiotracers for imaging in both the preclinical and clinical settings. The enzymatic radiofluorination overcomes many of the limitations encountered to date with purely chemical approaches. The bacterial enzyme lipoic acid ligase was used to conjugate [18F]-fluorooctanoic acid to both a small peptide and a Fab antibody fragment. Labeling was site-specific and highly efficient under mild aqueous conditions using small amounts of peptide/protein (1-10 nmol). The labeled construct retained full epitope binding affinity and was stable in mouse serum. Using an optimized reaction scheme, mCi quantities of [18F]-Fab were generated, an amount sufficient for human imaging.

The present disclosure provides antisense oligonucleotides, compositions, and methods that target a LIPA intron flanking exon 8, thereby modulating splicing of LIPA pre-mRNA to increase the level of LIPA mRNA molecules having exon 8, e.g., to provide a therapy for Wolman Disease or Cholesteryl Ester Storage Disease. The present disclosure provides an antisense oligonucleotide including a nucleobase sequence at least 70% complementary to a LIPA pre-mRNA target sequence in a 5'-flanking intron, a 3'-flanking intron, or a combination of exon 8 and the 5'-flanking or 3'-flanking intron.
