Molecular Characterization

HAO-1(Leu 2 - Ile 370)AAI13666

This protein carries a polyhistidine tag at the N-terminus.

The protein has a calculated MW of 41.7 kDa. The protein migrates as 41.7 kDa under reducing (R) condition (SDS-PAGE).


Less than 1.0 EU per μg by the LAL method.



>95% as determined by SDS-PAGE.


Lyophilized from 0.22 μm filtered solution in 50 mM Tris, 150 mM NaCl, pH7.5. Normally trehalose is added as protectant before lyophilization.

Hydroxyacid oxidase 1 (HAO-1), a member of the FMN-dependent alpha-hydroxy acid dehydrogenase family, is also known as glycolate oxidase (GOX), which contains 1 FMN hydroxy acid dehydrogenase domain. HAO-1 Has 2-hydroxyacid oxidase activity. Most active on the 2-carbon substrate glycolate, but is also active on 2-hydroxy fatty acids, with high activity towards 2-hydroxy palmitate and 2-hydroxy octanoate.
