What is spinal muscular atrophy (SMA)?
SMA is a genetic disorder characterized by the degeneration of motor neurons, leading to muscle weakness and atrophy.
How do antisense oligonucleotides work?
AONs modulate gene expression by binding to specific RNA sequences, influencing splicing and translation.
What are the advantages of lipotransfection?
Lipotransfection is fast, easy to perform, and sensitive enough for various AON chemistries.
Can this method be used for other cell types?
Yes, the protocol can be applied to primary myoblasts and other cell lines.
Who demonstrates the procedure in the article?
The procedure is demonstrated by Aleks, a technician from the laboratory.
