A simple and sensitive method was developed for the quantification of serum total 3alpha-hydroxy bile acids. 0.1 ml of serum was mixed with tris(hydroxymethyl) aminomethane hydrochloric acid buffer and heated at 67 degrees C for 30 min. To the solution were added 3alpha-hydroxysteroid : oxidoreductase (EC; 3alpha-HSD), NAD, diaphorase (EC and resazurin. The mixture was incubated at 20 degrees C for 1 h. The resultant fluorescence of resorfin was measured at 580 nm with the… CONTINUE READING
