| Output Notes | Much less splice-correction than KLA-PNA at 1 µM. Confocal microscopy (FAM-PNA-KLA) showed punctate cytosolic signal (endosomal sequestration) without agents, and increased nuclear uptake with chloroquine; nevertheless only slight enhancement of activity vs KLA-PNA. |
| Toxicity Notes | MAP-derived (KLA/RLA/ELA) conjugates showed cytotoxicity at higher concentrations (reported ~20% viability at 4 µM by MTT). |
