Field Specification
Mfr No pka-256
Biological Activity ~125-175 units/mg. One unit of MEK1 activity transfers 1 nmol of phosphate to ERK1/2 peptide per minute at 30°C in a reaction containing 100µM ATP. Recombinant active MEK1 also phosphorylates ERK1, ERK2, and GSK-3?. Kinase activity may vary depending on the substrate and reaction conditions. The optimal concentration should be determined for each specific application.

Target MAP2K1

Recombinant Human Mitogen Activated Kinase Kinase 1 is supplied as a recombinant protein for in vitro research use.

Background

MAP2K1 is a member of the dual specificity protein kinase family, which plays a role as a mitogen-activated protein (MAP) kinase kinase. MAP kinases, are recognized as extracellular signal-regulated kinases (ERKs), that act as an integration position for multiple biochemical signals. MEK1 is located upstream of MAP kinases and stimulates the enzymatic activity of MAP kinases upon wide variety of extra- and intracellular signals. As a key player of MAP kinase signal transduction pathway, MEK1 is involved in many cellular processes such as proliferation, differentiation, transcription regulation and development. MAP2K1 catalyzes the concomitant phosphorylation of a threonine and a tyrosine residue in a thr-glu-tyr sequence located in map kinases. MEK1 activates erk1 and erk2 map kinases.

Product format

Provided as a recombinant protein suitable for in vitro workflows such as binding studies, screening, and assay development. Refer to the specifications table for expression format and molecular properties.

What is the purity of Recombinant Human Mitogen Activated Kinase Kinase 1 (Human)?
Greater than 90% as determined by SDS-PAGE. BioHippo includes a Certificate of Analysis (CoA) confirming purity per lot with every order.
What buffer / formulation is this protein supplied in?
Supplied as: MEK1 is supplied at a concentration of in 40mM Tris, pH-8, 0.15M NaCl, 0.27M sucrose, 1mM DTT, 0.2mM PMSF, 1mM benzamidine, 0.1mM sodium vanadate and 0.03% Brij-35. Reconstitute lyophilized material in sterile ultrapure water or the recommended buffer per the datasheet prior to use.
How should Recombinant Human Mitogen Activated Kinase Kinase 1 (Human) be stored?
Store at 4°C if entire vial will be used within 1-2 weeks. Store frozen at -20°C for longer periods of time. Avoid multiple freeze-thaw cycles. Prepare single-use aliquots after reconstitution to avoid repeated freeze–thaw cycles.
What expression system was used to produce this protein?
This recombinant protein was expressed in Insect (Sf9/Baculovirus). The system was selected to achieve high yield, correct folding, and appropriate post-translational modifications.
Is this protein biologically active?
~125-175 units/mg. One unit of MEK1 activity transfers 1 nmol of phosphate to ERK1/2 peptide per minute at 30°C in a reaction containing 100µM ATP. Recombinant active MEK1 also phosphorylates ERK1, ERK2, and GSK-3?. Kinase activity may vary depending on the substrate and reaction conditions. The optimal concentration should be determined for each specific application. Refer to the product datasheet for recommended assay conditions and controls.
Is this protein approved for clinical or in vitro diagnostic use?
No. Supplied for Research Use Only (RUO) — not intended for therapeutic applications or in vitro diagnostic procedures.
Can I request a custom size, tag variant, or formulation?
Yes. BioHippo can accommodate custom requests including alternative sizes, His/GST/Fc tag variants, bulk quantities, and custom formulations. See the Customization & Add-ons tab or email support@biohippo.com.
