T9 peptide

The T9 peptide (SKTFNTHPQSTP) is a muscle-targeting ligand that binds tightly to C2C12 myoblasts. When conjugated to oligonucleotides, it enhances delivery specificity to cardiac and skeletal muscle (e.g., quadriceps) in vivo, while showing reduced off-target accumulation in organs like the liver and kidney, making it valuable for targeted therapeutic research.
