Isoelectric Focusing and PCR-RFLP Joined Techniques for Alpha1-antitrypsin Deficiency Detection

53 persons suspected to alpha1-antitrypsin deficiency detection (AATD) were investigated for ZZ, MZ, ZS, SS, and MS alleles analysis by serum protein electrophoresis (SPE), measurement of trypsin inhibiting capacity (TIC), isoelectric focusing (IEF), polymerase chain reaction (PCR), and IEF/PCR-RFLP techniques. The result clearly shows by using SPE and TIC techniques only 35.85 % and 50.08% of ...

بررسی ترکیبات گلیکوزیله نهایی آلبومین سرم (AGE) در افراد دیابتی به روش ایزوالکتریک فوکوسینگ (IEF) و فلورسانس جهت ارزیابی پیشرفت بیماری دیابت

Background: The non-enzymatic glycosylation (NEG) of proteins in diabetes damages both the structure and function of these proteins. In vivo and in vitro studies have shown that NEG of proteins and advanced glycosylation end-products (AGE) contribute to the pathogenesis of both macrovascular, such as atherosclerosis, and microvascular complications, such as retinopathy and nephropathy, in diabe...

Whole-Column-Imaging Detection for Capillary Isoelectric Focusing and Capillary Electrophoresis

Despite the significant advantages of capillary isoelectric focusing over gel isoelectric focusing, widespread acceptance of the technique as a replacement for gel isoelectric focusing has not occurred. Several factors contribute to capillary isoelectric focusing’s slower-than-expected adoption; perhaps the most important are the performance and procedural difficulties introduced when capillary...

Parallel implementation of finite volume based method for isoelectric focusing

A message passing interface (MPI) based parallel simulation algorithm is developed to simulate protein behavior in non-linear isoelectric focusing (IEF). The mathematical model of IEF is formulated based on mass conservation, charge conservation, ionic dissociation-association relations of amphoteric molecules and the electroneutrality condition. First, the concept of parallelism is described f...

Optimizing Conditions for Capillary Isoelectric Focusing Separations Using

Multiple forms of choline acetyltransferase in several species demonstrated by isoelectric focusing.

1. The behaviour of choline acetyltransferase from pigeon, guinea-pig, rat and cat brain on isoelectric focusing was studied. 2. Choline acetyltransferase from pigeon and guinea-pig brain showed single peaks with isoelectric points at pH6.6 and 6.8 respectively. Only one molecular form of the enzyme was therefore detected in these species. 3. Three peaks of choline acetyltransferase activities ...
