Actin (bovine alpha cardiac actin) 10x1.0mg
Actin
α-cardiac actin, bovine.
Description
| Protein | Actin (α-Actin) |
| Origin | Cardiac muscle, bovine |
| Molecular mass | 42 kDa |
| Protein description | Bovine cardiac α-actin is a highly conserved, single-chain globular protein with a molecular mass of approximately 42 kDa and a length of 375 amino acids. It is a major structural and contractile protein of muscle tissue and one of the principal components of thin filaments. In cardiac muscle, actin interacts with myosin and regulatory proteins to support ATP-dependent contraction. Hypermol® bovine cardiac actin is purified from native tissue and is suitable for biochemical, immunological and cell-biological applications requiring purified native actin of defined tissue origin. |
| Purity | >99% by scanning densitometry. |
Properties
| Form | Lyophilized, ready-to-use. |
| Quantity per unit | 10 × 1 mg |
| Buffer | 2 mM Tris-HCl pH 8.2, 0.4 mM ATP, 0.5 mM DTT, 0.1 mM CaCl2, 1 mM NaN3 and 0.3% disaccharides, when reconstituted with 1.0 ml ultrapure water to obtain a 1 mg/ml solution. |
| Related products | For dilution of G-actin or exchange of ligand buffer into actin-compatible buffer, MonoMix (Cat. #: 5100-0*) may be used. In the absence of nucleators, polymerization of G-actin is initiated by PolyMix (Cat. #: 5000-0*). |
