Unlabeled Actin

We specialize in isolating highly pure and functional actin protein from eukaryotic cells/tissue.  Our in-house production facilitates tight control over the quality, consistency, and availability of our protein reagents, and we promote full transparency into our production pipeline.  Our stock products include >99% pure and >90% pure actin protein derived from rabbit skeletal muscle.  Our >99% pure Ultra-Pure Actin demonstrates superior polymerization activity with >90% of the protein incorporating into filaments as assessed by pelleting assay.  Our >90% pure Pure Actin demonstrates >80% polymerization competency and possible contaminants include α -actinin (not in excess of 10%).  Both actin protein reagents are lyophilized for long-term storage at ambient temperatures and intended for in vitro research applications.

As stock products, both our Ultra-Pure Actin and Pure Actin are available for next-day delivery to your benchtop.  We also offer custom purification and labeling services when a particular actin species, storage buffer, or aliquot size is desired – inquire here.
