Anti-TNNI1 Antibody

Produced in rabbit hosts, this unconjugated polyclonal IgG reagent targets TNNI1, the slow-twitch skeletal muscle isoform of troponin I, and is validated for Western blot detection in mouse and rat sample lysates. Supplied as a 200 µl liquid aliquot, the antibody is intended for research use only and fits standard immunoblotting workflows following SDS-PAGE separation and transfer to nitrocellulose or PVDF membranes. For long-term integrity, the vial should be stored at -20°C in small working aliquots to limit repeated freeze-thaw cycles, with active working stocks kept briefly on ice during use. The product belongs to the Antibodies.com Primary Antibodies range and pairs with HRP- or fluorophore-conjugated secondary reagents for chemiluminescent or fluorescent visualization of the TNNI1 protein band on blot membranes. Researchers studying skeletal muscle development, contractile protein regulation, or comparative isoform expression between slow and fast twitch fibers will find the reagent useful for probing tissue-specific troponin patterns, where TNNI1 serves as a marker distinct from the cardiac isoform TNNI3 and the fast-twitch skeletal isoform TNNI2.
