Anti-ERK5 Antibody, clone 2H15 ZooMAb^® Rabbit Monoclonal

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.

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.

Reconstitute lyophilized antibody pellet with 25μL of ultrapure water or Phosphate Buffered Saline (PBS). Please refer to our reconstitution protocol and the specific application guidance on the suggested starting dilutions and sample type.

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.

Mitogen-activated protein kinase 7 (UniProt: Q13164; also known as EC:2.7.11.24, MAP kinase 7, MAPK 7, Big MAP kinase 1, BMK-1, Extracellular signal-regulated kinase 5, ERK-5) is encoded by the MAPK7 (also known as BMK1, ERK5, PRKM7) gene (Gene ID: 5598) in human. ERK5 is an unusual protein kinase with a kinase domain (aa 55-347) and a transcriptional transactivation domain (aa 664-789). It is expressed in many adult tissues and higher expression is observed in heart, placenta, lung, kidney, and skeletal muscle. Although its kinase domain  displays high sequence identity with ERK1/2, they tend to have distinct substrates and unlike ERK1/2, it has a large C-terminal extension that contains a NuCLEAR^™ localization signal (aa 505-539) and the transcriptional transactivation domain. ERK5 plays a role in various cellular processes, including cell proliferation, differentiation, and cell survival. Its upstream activator is MAP2K5 and following activation, it translocates to the nucleus and phosphorylates various downstream targets. It is activated by Dual^® phosphorylation of threonine 219 and tyrosine 221. ERK5 is also important for endothelial function and maintenance of blood vessel integrity. ERK5-deficient mice die around embryonic day 10.5 because of cardiovascular defects and angiogenic failure in embryonic and extraembryonic tissues.  Four isoforms of ERK5 have been described that are produced by alternative splicing. This ZooMAb^® recombinant monoclonal antibody, generated by our propriety technology, offers significantly enhanced specificity, Affinity^™, reproducibility, and stability over conventional monoclonals.
