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.

Target description

Mitogen-activated protein kinase 3 (UniProt: P21708; also known as EC:, MAP kinase 3, MAPK 3, ERT2, Extracellular signal-regulated kinase 1, ERK-1, Insulin-stimulated MAP2 kinase, MAP kinase isoform p44, p44-MAPK, MNK1, Microtubule-associated protein 2 kinase, p44-ERK1) is encoded by the Mapk3 (also known as Erk1, Prkm3) gene (Gene ID: 50689) in rat. ERK-1 is a serine/threonine kinase that acts as an essential component of the MAP kinase signal transduction pathway. It is expressed in different tissues, mostly in intestine, placenta, and lung. Highest levels have been reported in the nervous system. The MAPK/ERK cascade mediates several diverse biological processes such as cell growth, adhesion, survival, and differentiation through the regulation of transcription, translation, and cytoskeletal rearrangements. It also plays also a role in initiation and regulation of meiosis, mitosis, and post-mitotic functions in differentiated cells by phosphorylating a few transcription factors. About 160 substrates have been described for ERKs. The protein kinase domain of ERK-1 is localized to amino acids 43-331 and the TXY motif is located in amino acids 203-205. ERK-1 is phosphorylated by MEK1 and MEK2 on threonine 203 and tyrosine 205 in response to external stimuli like insulin or nerve growth factor and both these phosphorylations are essential for its activity. Two isoforms of ERK-1 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.

Physical form

Purified recombinant rabbit monoclonal antibody IgG, lyophilized in PBS with 5% Trehalose, normal appearance a coarse or translucent resin. Contains no biocide or preservatives, such as azide, or any animal by-products. Larger pack sizes provided as multiples of 25 μL.


30 μg/mL after reconstitution at 25 μL. 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.
