Synonyms
Tropomyosin alpha-4 chain, TM30p1, Tropomyosin-4, TPM4.
Introduction
TPM4 is a member of the tropomyosin family. Tropomyosins exist in practically all eukaryotic cells (both muscle and nonmuscle), where they bind actin filaments and function to modulate actin-myosin interaction and stabilize actin filament structure. TPM4 binds to actin filaments in muscle and nonmuscle cells and plays a central role, in connection with the troponin complex, in the calcium dependent regulation of vertebrate striated muscle contraction.
Description
TPM4 produced in E.Coli is a single, non-glycosylated polypeptide chain containing 268 amino acids (1-248 a.a.) and having a molecular mass of 30.7kDa.
TPM4 is fused to a 20 amino acid His-tag at N-terminus & purified by proprietary chromatographic techniques.
Source
Escherichia Coli.
Physical Appearance
Sterile Filtered colorless solution.
Formulation
The TPM4 solution (1 mg/ml) contains 20mM Tris-HCl buffer (pH 8.0), 10% glycerol, 2mM DTT and 0.1M NaCl.
Stability
Store at 4°C if entire vial will be used within 2-4 weeks. Store, frozen at -20°C for longer periods of time.
For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).
Avoid multiple freeze-thaw cycles.
Purity
Greater than 85.0% as determined by SDS-PAGE.
