摘要:
The present invention provides a process for stabilizing creatine kinase by disulphide modification, wherein creatine kinase is reacted in any desired sequence(a) with a molar excess of disulphide and/or thiosulphonate and(b) with a molar excess of water-soluble carbohydrate as carrier.
摘要:
The present invention provides a control reagent for test strips for the detection of urobilinogen and possibly of other diagnostically relevant components, such as bilirubin, ketone bodies, glucose, protein, nitrite and blood, and possibly also of pH, which has a content of 2,4-dimethylpyrrole-3-carboxylic acid and/or of at least one alkali metal and/or alkaline earth metal salt thereof as control substance for urobilinogen.
摘要:
A standard solution containing thyroxine-binding globulin (TBG) and thyroxine or triiodothyronine dissolved in a buffer solution is used for calibration in a method for the determination of thyroxine (T.sub.4) or triiodothyronine (T.sub.3) in serum, wherein both human and bovine TBG can be used.
