ZooMAb^® antibodies represent an entirely new generation of recombinant monoclonal antibodies. Each ZooMAb^® antibody is manufactured using our proprietary recombinant expression system, purified to homogeneity, and precisely dispensed to produce robust and highly reproducible lot-to-lot consistency. Only top-performing clones are released for use by researchers. Each antibody is validated for high specificity and affinity across multiple applications, including its most commonly used application. ZooMAb^® antibodies are reliably available and ready to ship when you need them.

Spécificité

Clone 5L4 is a ZooMAb^® rabbit recombinant monoclonal antibody that specifically detects phospho-Cofilin-1 (Ser3).

Immunogène

KLH-conjugated linear peptide corresponding to 10 amino acids surrounding phosphoserine 3 in human Cofilin-1.

Application

Quality Control Testing

Evaluated by Western Blotting in lysate from HeLa cells treated with Nocodazole.

Western Blotting Analysis (WB): A 1:1,000 dilution of this antibody detected phosphor-cofilin (Ser3) in lysate from overnight serum starved HeLa cells treated with Nocodazole (40 ng/mL; 8 h), but not in untreated cells.

Tested Applications

Western Blotting Analysis: A 1:1,000 dilution from a representative lot detected phospho-Cofilin (Ser3) in lysate from Chinese Hamster Ovary (CHO) cells, overnight serum starved and treated with Nocodazole (100 nM; 18 h).

Immunocytochemistry Analysis: A 1:100 dilution from a representative lot detected phospho-Cofilin (ser3) in MCF-7 cells, but not in cells treated with phosphorylated Cofilin (Ser3).

Peptide Inhibition Assay: Target band detection in lysate from HeLa cells treated with Nocodazole (40 ng/mL; 8 h) was prevented by pre-blocking of a representative lot with the immunogen phospho-peptide, but not the corresponding non-phospho-peptide.

Note: Actual optimal working dilutions must be determined by end user as specimens, and experimental conditions may vary with the end user.

Description de la cible

Cofilin-1 (UniProt P23528; also known as 18 kDa phosphoprotein, Cofilin non-muscle isoform, p18) is encoded by the CFL1 (also known as CFL) gene (Gene ID 1072) in human. Cofilin is an actin-binding protein that regulates filament dynamics and depolymerization. Cofilin-1 (non-muscle cofilin), cofilin-2 (muscle cofilin), and actin-depolymerizing factor (ADF) play an essential role in regulating actin filament dynamics and reorganization by stimulating the severance and depolymerization of actin filaments. The three cofilin family members share 70% to 81% sequence identity, exhibit similar biological functions, and display distinct but overlapping expression patterns. Cofilins and ADF bind actin monomers and filaments (G-actin and F-actin) and increase the number of actin monomers and filament fragments, facilitating filament turnover and treadmilling at key locations in migrating cells. Cofilins and ADF are inactivated by phosphorylation at serine 3 by LIM-kinases (LIMK) and testicular protein kinases (TESKs) and are reactivated by dephosphorylation by the slingshot (SSH) family of protein phosphatases and chronophin.  Cofilin-1 is required for the centralization of the mitotic spindle and symmetric division of zygotes. It also plays a role in the regulation of cell morphology and cytoskeletal organization in epithelial cells and is shown to be essential for neural tube morphogenesis and neural tube cell migration. Cfl1-knockout mice display embryonic lethality at E11.5 - E12.5 due to aberrant neural tube closure and defective neural crest cell migration, while Adf-deficient mice are viable with normal brain appearance but suffer from corneal defects that cause blindness in adult mice. Over-expression of cofilins is observed in various cancers where it promotes cancer metastasis by regulating cytoskeletal reorganization, lamellipodium formation, and epithelial-to-mesenchymal transition. This ZooMAb^® recombinant monoclonal antibody, generated by our propriety technology, offers significantly enhanced specificity, affinity, reproducibility, and stability over conventional monoclonals.

Forme physique

Purified recombinant rabbit monoclonal antibody IgG, lyophilized in PBS, 5% Trehalose, normal appearance a coarse or translucent resin. The PBS/trehalose components in the ZooMAb formulation can have the appearance of a semi-solid (bead like gel) after lyophilization. This is a normal phenomenon. Please follow the recommended reconstitution procedure in the data sheet to dissolve the semi-solid, bead-like, gel-appearing material. The resulting antibody solution is completely stable and functional as proven by full functional testing. Contains no biocide or preservatives, such as azide, or any animal by-products. Larger pack sizes provided as multiples of 25 µL.

Reconstitution

300 µg/mL after reconstitution at 25 µL per vial. Please refer to guidance on suggested starting dilutions and/or titers per application and sample type.

Stockage et stabilité

Recommend storage of lyophilized product at 2-8°C; Before reconstitution, micro-centrifuge vials briefly to spin down material to bottom of the vial; Reconstitute each vial by adding 25 µL of filtered lab grade water or PBS; Reconstituted antibodies can be stored at 2-8°C, or -20°C for long term storage. Avoid repeated freeze-thaws.
