Clone Host Grade Applications
Monoclonal Mouse Affinity Purified E B
Troponin I is a 24kD subunit of Troponin, a protein found on muscle tissue responsible for muscle contraction. When calcium binds to Troponin C, a conformational change moves Troponin I and tropomyosin out of the way of the myosin binding sites on the actin filaments in muscles. This allows cross-bridging to occur and the muscle to contract. Levels of cTnI in serum are commonly used as a marker for cardiac cell damage and death. Phosphorylation of cTnI results in changes in the activity and function of Troponin. One possible form of phosphorylation is by Protein kinase A. Protein kinase A phosphorylation of serine 22 and serine 23 reduces calcium sensitivity of Troponin and leads to an acceleration in relaxation. Changes in cTnI phosphorylation have been reported in failing hearts.
Catalog #T8665-18M
ApplicationsSuitable for use in ELISA and Western Blot. Other applications not tested.
Recommended DilutionsWestern Blot: For the detection of phosphoproteins, phosphatase inhibitors such as 10mM sodium fluoride and 1mM sodium orthovanadate should be added to the sample buffer. Milk or other casein-based blocking solutions are not recommended as casein is a phosphoprotein and its use can result in high background.
Optimal dilutions to be determined by the researcher.
HybridomaSp2/0 myeloma cells with spleen cells from Balb/c mice.
