Our Abpromise guarantee covers the use of ab14133 in the following tested applications.

The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.

Application Abreviews Notes
WB Use a concentration of 1 µg/ml. Detects a band of approximately 21 kDa.


  • Function
    Controls reversibly actin polymerization and depolymerization in a pH-sensitive manner. It has the ability to bind G- and F-actin in a 1:1 ratio of cofilin to actin. It is the major component of intranuclear and cytoplasmic actin rods.
  • Tissue specificity
    Isoform CFL2b is expressed predominantly in skeletal muscle and heart. Isoform CFL2a is expressed in various tissues.
  • Involvement in disease
    Defects in CFL2 are the cause of nemaline myopathy type 7 (NEM7) [MIM:610687]. A form of nemaline myopathy. Nemaline myopathies are muscular disorders characterized by muscle weakness of varying severity and onset, and abnormal thread-or rod-like structures in muscle fibers on histologic examination. Nemaline myopathy type 7 presents at birth with hypotonia and generalized weakness. Major motor milestones are delayed, but independent ambulation is achieved.
  • Sequence similarities
    Belongs to the actin-binding proteins ADF family.
    Contains 1 ADF-H domain.
  • Post-translational
    The phosphorylation of Ser-24 may prevent recognition of the nuclear localization signal.
  • Cellular localization
    Nucleus matrix. Cytoplasm > cytoskeleton.

Customer reviews and Q&As


Thank you for your enquiry and your interest in our products. We regret to inform you that the cross-reactivity of ab11062 (cofilin 1) with cofilin 2 has not been tested yet. On the basis of poor sequence homology between human Cofilin 1 and Cofilin 2 for the sequence used as the immunogen for ab14133, it appears very unlikely that antibody will cross- react with human Cofilin 1. If you look at the large amount of homology throughout most of the two sequences until you get to aa 136, it is clear that this fragment was chosen to distinguish the two isoforms.
