Fig. 2From: An extreme halophilic xylanase from camel rumen metagenome with elevated catalytic activity in high salt concentrationsAnalysis of purity, functional activity, and mode of action of XylCMS. a SDS-PAGE for purity analysis: Lane 1, protein molecular weight marker; Lane 2, purified XylCMS; b Zymogram prepared by Congo Red staining of a native PAGE gel indicating the functional activity of the purified enzyme as an unstrained area; c TLC analysis of OSX hydrolysis by XylCMS. Lane 1, enzyme-treated preparation; lane 2, control without enzyme; lane 3, standard molecular marker composed of mono-, di-, tri-, tetra-, and penta-glucose; lane 4, enzyme-treated preparation. The arrows indicate the hydrolysis products of OSXBack to article page
