Cofilin 1 + LIMK1 Phosphorylated


Application / Dilution
WB10 μl/lane

Size 100 μl



Members of the ADF/cofilin (AC) family are actin-severing proteins that regulate actin remodeling during cell migration, cytokinesis, axon development, and immune cell activation. In mammals, there are three members of the AC family, muscle-specific cofilin (cofilin 2), non-muscle cofilin (cofilin 1), and ADF. In humans, cofilin 1 and ADF have 72% identity, with the major amino acid differences found in the C-terminal region. Activation of cofilin kinases, LIMK1 or LIMK2, leads to phosphorylation of cofilin at serine 3. This phosphorylation disrupts cofilin binding to actin in vitro and in vivo.

For preparation of Ser-3 phosphorylated Cofilin, purified human Cofilin 1 was phosphorylated in vitro with His-tagged mouse recombinant LIM Kinase 1 for 30 min. at 37°C (Cat. #CL7321). For control lysate, the recombinant Cofilin 1 protein was exposed to buffer only (Cat.#CL7311). The phosphorylated product is detected by anti-Cofilin (Ser-3; Cat.#CP1151), while both the control and phosphorylated recombinant cofilin 1 are detected by anti-Cofilin (N-terminus; Cat.#CP1131).

Cofilin 1 Control Lysate is supplied at a concentration of 10 ng/µl in electrophoresis sample buffer (62.5 mM Tris pH 6.8, 2% SDS, 5% glycerol, 0.003% bromophenol blue, 0.9% β-mercaptoethanol). Store at –20°C. Do not boil or dilute. Stable for 1 year.

The products are are safely shipped at ambient temperature for both domestic and international shipments. Each product is guaranteed to match the specifications as indicated on the corresponding technical data sheet. Please store at -20C upon arrival for long term storage.

*All molecular weights (MW) are confirmed by comparison to Bio-Rad Rainbow Markers and to western blot mobilities of known proteins with similar MW.
