SARS coronavirus Plpro / papain-like protease
|Alternative Name :||none|
|Amount :||20 µg|
Source : E. coli
The methanol extract of T. terrestris fruits showed potent inhibition against the papain-like protease (PLpro), an essential proteolylic enzyme for protection to pathogenic virus and bacteria.Tribulus terrestris fruits are well known for their usage in pharmaceutical preparations and food supplements. The most active PLpro inhibitors (1-6) were proven to be present in the native fruits in high quantities by HPLC chromatogram and liquid chromatography with diode array detection and electrospray ionization mass spectrometry (LC-DAD-ESI/MS).
|Purification :||> 90 % as determined by SDS-PAGE.|
|Content :||Formulation Lyophilized from sterile 50 mM Tris, 0.1 % Tween, pH 9.0.
Normally 5 % - 8 % trehalose, mannitol and 0.01% Tween80 are added as protectants before lyophilization.
