Rabbit Skeletal Muscle Actin: Structure, Function, and Research Applications
A comprehensive guide to the core motor protein driving muscle contraction and cytoskeletal research.
Molecular Weight: ~43 kDa
Composition: 374 Amino Acid Residues
Form: Lyophilized Powder
Rabbit skeletal muscle actin is a foundational motor protein essential for muscle contraction. As one of the most highly conserved proteins in eukaryotic cells, it serves as a critical tool in biochemistry and cell biology laboratories worldwide.

Key Biological Characteristics
| Property | Description |
|---|---|
| Structural Transformation | Polymerizes from globular monomers (G-actin) into double-helical filaments (F-actin) with a 36 nm half-pitch. |
| Biological Function | Interacts with myosin to generate sliding filament contraction; maintains cytoskeletal integrity. |
| Stability | Features excellent thermal and pH stability, ensuring consistency across long-term experiments. |
Major Application Scenarios
ðŽ Scientific Research
- Enzyme protection and stabilization studies.
- Reference standard for quantitative Immunoblotting (Western Blot).
ð§Ŧ Cell Biology
- Investigation of cell motility and morphological regulation.
- In vitro cytoskeletal dynamics assays.
Storage and Handling Guidelines
To ensure maximum protein activity, please adhere to the following:
- Storage: Store the lyophilized powder at 2â8°C.
- Handling: Reconstitute according to protocol and avoid repeated freeze-thaw cycles to prevent protein degradation.
