Validation of free flow electrophoresis as a novel plasma and serum processing and fractionation method in biobanking.

Free flow electrophoresis (FFE) is a fractionation method, based on isoelectric focusing (IEF). We validate the reproducibility of the method and show that it can be applied by biobanks in order to fractionate fluid biospecimens efficiently and reproducibly and to facilitate downstream proteomic applications. We also propose a simple method allowing researchers to assess the reproducibility of ...

Development of Isoelectric Focusing Techniques for Protein Analyses

Isoelectric focusing (IEF) is a powerful approach in separations of zwitterionic substances such as proteins, peptides and amino acids. It is important in proteomic research. Generally, in IEF, carrier ampholytes (CAs) are necessary to establish a stable pH gradient. However, CAs also bring attendant problems such as a decrease in detection sensitivity and suppression of ionization of analytes ...

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 ...

Separation of bacterial cells by isoelectric focusing, a new method for analysis of complex microbial communities.

A simple isoelectric focusing (IEF) method for whole bacterial cells was developed. In a pH gradient of 2 to 10 and an electric field of 11.5 V cm-1, mixtures of cells from the three different bacterial strains Chlorobium limicola 6230, Pseudomonas stutzeri DSM 50227, and Micrococcus luteus DSM 20030 could be separated. A density gradient of Ficoll prevented convective currents in the system. T...
