p-Cofilin 1 Antibody (E-5) is a mouse monoclonal IgM antibody that detects p-Cofilin 1, specifically the Ser 3 phosphorylated form, in mouse, rat, and human samples through applications such as western blotting (WB), immunoprecipitation (IP), immunofluorescence (IF), immunohistochemistry, and enzyme-linked immunosorbent assay (ELISA). p-Cofilin 1 Antibody (E-5) is available in a non-conjugated format, allowing for versatile experimental use. Cofilin, a critical actin-binding protein, plays a vital role in regulating actin cytoskeleton, which is essential for various cellular processes, including motility, division, and shape maintenance. Phosphorylation of cofilin at Serine 3 by LIM-kinase 1 (LIMK-1) inhibits actin-depolymerizing activity, thereby stabilizing actin filaments and promoting cytoskeletal integrity. This regulation allows cells to respond dynamically to signaling cues, facilitating processes such as cell migration and tissue remodeling. Cofilin′s interaction with other actin-binding proteins further underscores cofilin′s importance in maintaining the delicate balance of actin dynamics within cells, making anti-p-Cofilin 1 antibody (E-5) an invaluable tool for researchers studying cytoskeletal organization and its implications in health and disease.

Does this antibody (or any of the other anti-cofilin antibodies currently available) recognize Drosophila Cofilin by IF?

Asked by: JSR1
Thank you for your question. Sequence analysis shows very low to no homology between the epitope sequence of the antibodies and the target in Drosophila. If you have additional questions, please contact Technical Support at 1800-457-3801 option 2, by emailing scbt@scbt.com or by live chat on our website at www.scbt.com so we may further assist you.

What application is the blocking peptide sc-271921 P appropriate for?

Asked by: Germaine
Thank you for your question. The blocking peptide is intended for use as a negative control, by pre-adsorbing the mouse monoclonal antibody against the antigen.

Rated 5 out of 5 by from Anti-p-Cofilin per analisi in western blotL'Ab è stato testato utilizzando lisati cellulari MCF-7 e MDA-MD-231, ottenuti in RIPA buffer. 15 ug di proteine sono state separate tramite SDS-Page e trasferite su un filtro di nitrocellulosa. Il bloccaggio è stato effettuato in Blotto A per 1h, l'Ab primario è stato utilizzato alla diluizione di 1:1000 in 10 mL di Blotto A per 1h. Il secondario 1:2000 in Blotto A per 1h. Il segnale ottenuto è pulito, con un'unica banda del perso molecolare atteso. La specificità del segnale è stata verificata utilizzando l'inibitore della chinasi ROCK, Y-27632.

Rated 5 out of 5 by from Very potent and highly specific antibodyThis monoclonal antibody was independently tested by Kinexus Bioinformatics Corporation and determined to be an excellent antibody for Western blotting. Strong detection of cofilin 1 was observed, but no cross-reactivities detected by Western blotting in HeLa cells exposed to anisomycin for 2 hours. No detection of the cofilin 1 target was observed in overnight-serum starved human A431 cells that were treated for 5 minutes with epidermal growth factor. However, there was no significant cross-reactivities on these A431 cell immunoblots with any off-target proteins.
