Recombinant Human ENPP-2 / Autotaxin Protein, His Tag, 50 µg

Background
Autotaxin also known as ectonucleotide pyrophosphatase / phosphodiesterase family member 2 (E-NPP 2 or ENPP2), Extracellular lysophospholipase D (LysoPLD), Autotaxin (ATX or ATX-X), which belongs to the nucleotide pyrophosphatase / phosphodiesterase family. ENPP2 contains two SMB (somatomedin-B) domains. ENPP2 hydrolyzes lysophospholipids to produce lysophosphatidic acid (LPA) in extracellular fluids. ENPP2 can act on sphingosylphosphphorylcholine producing sphingosine-1-phosphate, a modulator of cell motility. ENPP2 stimulates migration of melanoma cells, probably via a pertussis toxin-sensitive G protein.

Source
Recombinant Human ENPP-2, His Tag (EN2-H5241) is expressed from human 293 cells (HEK293). It contains AA Asp 49 - Ile 863 (Accession # NP_001035181).
Predicted N-terminus: His

Molecular Characterization
This protein carries a polyhistidine tag at the N-terminus.
The protein has a calculated MW of 94.5 kDa. The protein migrates as 90-100 kDa under reducing (R) condition (SDS-PAGE).

Endotoxin
Less than 1.0 EU per μg by the LAL method.

Purity
>95% as determined by SDS-PAGE.

Formulation
Lyophilized from 0.22 μm filtered solution in 50 mM Tris, 150 mM NaCl, pH 7.5. Normally trehalose is added as protectant before lyophilization.

Reconstitution
See Certificate of Analysis for details of reconstitution instruction and specific concentration.
For best performance, we strongly recommend you to follow the reconstitution protocol provided in the CoA.
