• Target description: Src substrate cortactin (UniProt: Q14247; also known as Amplaxin, Oncogene EMS1) is encoded by the CTTN (also known as EMS) gene (Gene ID: 2017) in human. Cortactin is a peripheral membrane protein that serves as a substrate for Src tyrosine kinase and plays a role in regulating cell motility. It is shown to interact with F-actin to promote its polymerization and branching and contributes to the organization of the actin cytoskeleton and cell shape. It also plays a role in the formation of lamellipodia and in cell migration. Cortactin contains an N-terminal acidic domain, six and a half tandem repeats of a unique 37-amino acid sequence, and a C-terminal Src homology (SH3) domain (aa 492-550). The repeat regions are shown to be essential for F-actin binding. Cortactin is activated via phosphorylation by upstream kinases in response to extracellular stimuli. In mice, Src kinase primarily phosphorylates cortactin at tyrosines 421, 466, and 482, which leads its interaction with F-actin and Arp2/3. It can also be phosphorylated by ERK on serine 405 and 418 that results in recruitment of additional actin nucleation-promoting factors (NPFs), most importantly N-WASP, to the Arp2/3/ complex. Cortactin can undergo acetylation by p300 and PCAF acetyltransferase and its acetylation sites are shown to cluster in the repeat region of cortactin harboring its F-actin binding site. Acetylated cortactin loses the positive charge at respective lysines that results in the loss of its F-actin binding. Overexpression of cortactin has been reported in many human tumors and its expression correlates well with the metastatic potential of breast cancer cells and hepatocellular carcinomas. Its level is associated with increased cell migration, metastasis, and poor prognosis. This ZooMAb® recombinant monoclonal antibody, generated by our propriety technology, offers significantly enhanced specificity, affinity, reproducibility, and stability over conventional monoclonals.

• Physical form: Purified recombinant rabbit monoclonal antibody IgG, lyophilized in PBS with 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: 30 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.
• Storage and Stability: 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.
