Troponin I, Cardiac, aa23-29 (cTnI, CMH7, Familial Hypertrophic Cardiomyopathy 7, TNNC1, Troponin I Type 3 Cardiac, TNNI3) (Biotin)

Troponin, working in conjunction with tropomyosin, functions as a molecular switch, regulating muscle contraction in response to changes in the intracellular Ca2+ concentration. Troponin consists of three subunits, the Ca2+-binding subunit troponin C (TnC), the tropomyosin-binding subunit troponin T (TnT), and the inhibitory subunit troponin I (TnI). Troponin I binds to actin in thin myofilaments to hold the actin-tropomyosin complex in place, because of which myosin cannot bind to actin in relaxed muscle. When Calcium binds to the Troponin C it causes certain confomational changes which leads to dislocation of troponin I. The letter “I” is given due to its inhibitory character.

The tissue specific subtypes are:
Slow-twitch skeletal muscle isoform troponin I, TNNI1 (1q31.3, 191042)
Fast-twitch skeletal muscle isoform troponin I, TNNI2 (11p15.5, 191043)
Cardiac troponin I, TNNI3 (19q13.4, 191044)

Applications:
Suitable for use in ELISA, Western Blot and Immunoaffinity Purification. Other applications not tested.

Recommended Dilutions:
Optimal dilutions to be determined by the researcher.

Hybridoma:
SP2/0 myeloma cells with spleen cells from Balb/c mice.

Storage and Stability:
Store product at 4°C if to be used immediately within two weeks. For long-term storage, aliquot to avoid repeated freezing and thawing and store at -20°C. Aliquots are stable at -20°C for 12 months after receipt. Dilute required amount only prior to immediate use. Further dilutions can be made in assay buffer. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap.

Note: Applications are based on unconjugated antibody.
