蛋白结构(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).
内毒素(Endotoxin)
Less than 1.0 EU per μg by the LAL method.
纯度(Purity)
>95% as determined by SDS-PAGE.
制剂(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.

Protocol
背景(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.
