Native Human TNNI3

• Cat.No.: TNNI3-221H
• Product Overview: Native Human TNNI3 was purified from Human cardiac tissue by Tn-C affinity chromatography.

Specification

• Cat. No.: TNNI3-221H
• Description: Troponin I (TnI), along with troponin T (TnT) and troponin C (TnC), is one of 3 subunits that form the troponin complex of the thin filaments of striated muscle. TnI is the inhibitory subunit; blocking actin-myosin interactions and thereby mediating striated muscle relaxation. The TnI subfamily contains three genes: TnI-skeletal-fast-twitch, TnI-skeletal-slow-twitch, and TnI-cardiac. This gene encodes the TnI-cardiac protein and is exclusively expressed in cardiac muscle tissues. Mutations in this gene cause familial hypertrophic cardiomyopathy type 7 (CMH7) and familial restrictive cardiomyopathy (RCM).
• Source: Human cardiac tissue
• Molecular Mass: 24 KDa
• Formulation: Liquid
• Storage buffer: 8 M Urea, 50 mM Tris.HCl, 15 mM ß-mercaptoethanol, 1 mM EDTA (pH 8.0)
• Applications: This peptide can be used with studies using ab7829, ab8290, ab8291 and ab137719.
• Biological activity: SDS PAGE profile of a typical recombinant Troponin-I preparation (3.8ug) showed a major band at 24kDa and a minor band attributable to Troponin-I dimer. Please note: Troponin-I is very susceptible to proteolytic breakdown within cardiac tissue and it is difficult to isolate undegraded native human cardiac troponin-I. This product is greater than 70% intact and hence proteolytic fragments can be observed.
• Storage: Aliquot and store at -80°C. Avoid repeated freeze / thaw cycles.
• OfficialSymbol: TNNI3
• Tag: Non
