Species cross-reactivity is determined by western blot.

Applications Key: W=Western Blotting,


Species predicted to react based on 100% sequence homology: Pig,

Specificity / Sensitivity

Phospho-Cofilin (Ser3) Antibody detects endogenous levels of cofilin only when phosphorylated at serine 3. The antibody may cross-react with phosphorylated cofilin 2, the muscle isoform.

Phospho-Cofilin (Ser3) 抗体仅识别serine 3磷酸化的内源性cofilin总蛋白。该抗体可能与磷酸化的cofilin 2(muscle isoform)发生交叉反应。

Source / Purification

Polyclonal antibodies are produced by immunizing animals with a synthetic phosphopeptide corresponding to residues surrounding Ser3 of human cofilin. Antibodies are purified by protein A and peptide affinity chromatography.


Western Blotting

Western Blotting

Western blot analysis of extracts from HeLa cells, untreated or H2O2-treated, using Phospho-Cofilin (Ser3) Antibody (A and B) or Cofilin Antibody #3312 (C and D). Membranes (B and D) were treated with alkaline phosphatase (CIP) to demonstrate the phospho-specificity the antibody. 使用Phospho-Cofilin (Ser3) Antibody (A和B)或Cofilin Antibody #3312 (C和D),免疫印迹(Western Blot)分析HeLa细胞系,细胞分为untreated组或H2O2-treated组。alkaline phosphatase (CIP)处理膜(B和D)从而证明磷酸化特异性抗体。

Western Blotting

Western Blotting

Western blot analysis of extracts from asynchronous or mitotic C6, CHO and COS cells, using Phospho-Cofilin (Ser3) Antibody (upper) or Cofilin Antibody #3312 (lower). 使用Phospho-Cofilin (Ser3) Antibody (上图)或Cofilin Antibody #3312 (下图),免疫印迹(Western Blot)分析不同时期或有丝分裂期的C6、CHO和COS细胞系中Phospho-Cofilin (Ser3)和Cofilin蛋白水平。


Cofilin and ADF (actin-depolymerization factor) 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).
