Implication

May enable isoform-selective targeting in muscle disease; leaves open human validation and clinical translation.

Key Points

This research aimed to develop monoclonal antibodies that differentiate between titin from heart and skeletal muscle.
Monoclonal antibodies were elicited using a chicken heart muscle residue as the antigen.
Immunoblot analysis and immunofluorescence microscopy were used to examine antibody reactivity with titin in various muscle types.
The study included immunoelectron microscopy to analyze titin localization in muscle tissue.
Antibodies T1 and T4 specifically recognize only the upper band of the titin doublet in skeletal muscle but not in cardiac muscle.
Antibody T3 reacts with heart titin, showing distinct immunological responses.
Titin localization was confirmed at the A-I junction in skeletal muscle, while in heart tissue, T1 and T4 reacted within the I-band.
