Protocols

Specificity / Sensitivity

Cofilin (D3F9) XP® Rabbit mAb (HRP Conjugate) detects endogenous levels of total cofilin1 protein.

Source / Purification

Monoclonal antibody is produced by immunizing animals with a synthetic peptide corresponding to central residues of human cofilin1 protein.

Western Blotting

Western Blotting

Western blot analysis of extracts from COS-7 and HeLa cells using Cofilin (D3F9) XP® Rabbit mAb (HRP Conjugate).

Description

This Cell Signaling Technology® antibody is conjugated to the carbohydrate groups of horseradish peroxidase (HRP) via its amine groups. The HRP conjugated antibody is expected to exhibit the same species cross-reactivity as the unconjugated Cofilin (D3F9) XP® Rabbit mAb #5175.

Background

Cofilin and actin-depolymerization factor (ADF) are members of a family of essential conserved small actin-binding proteins that play pivotal roles in cytokinesis, endocytosis, embryonic development, stress response, and tissue regeneration (1). In response to stimuli, cofilin promotes the regeneration of actin filaments by severing preexisting filaments (2). The severing activity of cofilin is inhibited by LIMK or TESK phosphorylation at Ser3 of cofilin (3-5). Phosphorylation at Ser3 also regulates cofilin translocation from the nucleus to the cytoplasm (6).
