肌动蛋白

产品英文名称：
Actin

英文简称:
Actin

中文名称:
肌动蛋白

背景资料:
Actin is a muscle protein localized in the I band of the myofibrils； acting along with myosin， it is responsible for contraction and relaxation of muscle. Each actin protomer binds one molecule of ATP and has one high a兔肌肉组织中提取纯化inity site for either calcium or magnesium ions， as well as several low a兔肌肉组织中提取纯化inity sites. Actin exists as a monomer in low salt concentrations， but filaments form rapidly as salt concentration rises， with the consequent hydrolysis of ATP. It occurs in globular （G-actin） and fibrous （F-actin） forms. Actin is found in all eukaryotic cells （except for nematode sperm）. Actin is one of the most highly-conserved proteins， di兔肌肉组织中提取纯化ering by no more than 20% in species as diverse as algae and humans. Its other functions include: cell motility， cell division and cytokinesis， vesicle and organelle movement， cell signaling， and the establishment and maintenance of cell junctions and cell shape.

溶解建议:
Sterile Filtered White lyophilized （freeze-dried） powder. The protein was lyophilized from a 1mg/ml solution containing 10mM Tris/HCl buffer pH 8.0， 0.2mM CaCl2， 0.2mM ATP， 1mM DTT and 0.5% （w/v） SDS.It is recommended to reconstitute the lyophilized Actin in sterile 18MΩ-cm H2O not less than 100ug/ml， which can then be further diluted to other aqueous solutions.

保存建议：
Lyophilized Actin although stable at room temperature for 3 weeks， should be stored desiccated below -18℃. Upon reconstitution Actin should be stored at 4℃ between 2-7 days and for future use below -18℃. For long term storage it is recommended to add a carrier protein （0.1% HSA or BSA）. Please prevent freeze-thaw cycles.
