Evaluationof CurrentMethodsfor Creatine Kinase lsoenzymeFractionation

چکیده
I have evaluated electrophoretic, ion-exchange, kinetic, selective activation, and immunological methods of fractionating creatine kinase isoenzymes for diagnostic purposes. The last three were unsuitable. Electrophoretic methods had superior resolution and reliability, but were relatively insensitive when conventional film-drying techniques were used. With elution from the film, sensitivity was comparable to that of the ion-exchange methods. Electrophoretic methods require more skill than the other methods. Ion-exchange methods had acceptable resolution and reliability with potentially superior sensitivity; they require less skill than electrophoresis, but require about as much time. Batch operation of ion-exchange yielded superior efficiency and sensitivity, and was otherwise comparable to column operation.

Background Nicotine, cotinine and cadmium are harmful components of cigarettes that have an effect on human reproductive function. Although the effects of cigarette smoke on male reproductive function is characterized in several articles its mechanism of action is still unknown. In the present study, we investigate the effect of nicotine, cotinine and cadmium on human sperm creatine kinase acti...

متن کاملNOVEL REAGENTS FOR CREATINE KINASE
The purpose of this investigation was to develop a simple colorimetric method for creatine kinase (CK). The new method is based on the reaction of creatine, formed enzymatically from creatine phosphate and ADP, with different glyoxal compounds. Hydrated glyoxals, such as para-nitrophenyl, 2-thiophene, 4- biphenyl, 4, 4' -biphenyl,α-naphthyl, β-naphthyl, para-chlorophenyl, and styryl were...
