A number of enzymes, including amylases, dehydrogenases, and proteases, were shown to be renaturable after polyacrylamide gel electrophoresis in the presence of sodium dodecyl sulfate. Enzyme activity was detected in situ by action on substrates introduced into the gel and subsequent staining of either the product or unreacted substrate. This technique combines the advantage of enzyme identific...
A recent study found that an agarose gel electrophoresis (AGE) method yielded two distinct major bands corresponding to the hepatic and bone ALP isoenzymes (ALP2 ALP3, respec-tively) in bovine serum treated with protease neuraminidase (PN-treatment), although there were concerns intestinal isoenzyme (ALP5) often overlapped ALP3 human neuraminidase. Because ALP5 was separated from alone (P-treat...
In this study, Aspergillus niger lipase after extraction of medium culture was precipitated with different percentages of acetone and purified by ion exchange chromatography using SP-sepharose HP and Q-sepharose HP. The process of purification of the anzyme was studied by electrophoresis and the molecular weight was detected and determined by Zymography using overlying containing phenol red and...

Posch, and W. Weiss. 1995. Two-dimensional polyacrylamide gel electrophoresis with immobilized pH gradients in the first dimension (IPG-Dalt): the state of the art and the controversy of vertical versus horiz...
PURPOSE To evaluate reasons for non-compliance with post-cataract surgical follow-up in rural China, and assess the impact of incentives on improving compliance. METHODS Patients having undergone cataract surgery more than 3 months previously at cataract surgery training hospitals in Guangdong were invited by telephone and advertisements to a hospital-based study examination, with compensatio...
a simple, rapid new technique is described for the electrophoresis of hemoglobin when screening large human populations. the method uses a drop of finger tip's blood dried on a thick filter paper as the specimen. the simplicity of the sampling, tagging, transportation and electrophoresis, provides a reliable procedure for surveys of large population. in our hand 200 specimens were screened dur...
background and objectives: making stacking gels for polyacrylamide gels in the laboratory by conventional methods is laborious and time consuming. considering the role of temperature in polyacrylamide gels with respect to electrical resistance and viscosity, we assumed that decreasing the temperature would cause an increase in electrical resistance and viscosity. ultimately, a downward tempera...
We assessed the changes in sensitivity and specificity of creatine kinase (CK) isoenzymes at various times after acute myocardial infarction. CK-B was measured by an immunoinhibition technique. CK-MB was measured both by column chromatography on Sephadex DEAE A-50 and by electrophoresis on agarose gel. For CK-B, the sensitivity in detecting infarct varied from 11% in the first 8 h after onset o...
