Laser microdissection and two-dimensional difference gel electrophoresis with alkaline isoelectric point immobiline gel reveals proteomic intra-tumor heterogeneity in colorectal cancer

Two-dimensional gel electrophoresis, isoelectric focusing and agarose gel electrophoresis in the diagnosis of multiple sclerosis.

Two dimensional gel electrophoresis (2-DE), isoelectric focusing (IEF) and agarose gel electrophoresis (AGE) were used to examine cerebrospinal fluid (CSF) and sera from 22 patients with confirmed multiple sclerosis, 11 patients with probable multiple sclerosis and 20 control patients with non-inflammatory neurological diseases of the central nervous system (CNS). All of the 22 patients with co...

Two Dimensional Gel Electrophoresis in Cancer Proteomics

Two-dimensional electrophoresis (2-DE) is a powerful and widely used method for the analysis of complex protein mixtures extracted from cells, tissues, or other biological samples. This technique sort’s protein according to two independent properties in two discrete steps: the first-dimension step, isoelectric focusing (IEF), separates proteins according to their isoelectric points (pI); the se...

Two-dimensional Gel Electrophoresis

Alkaline agarose gel electrophoresis.

INTRODUCTION Alkaline agarose gels are run at a pH that is sufficiently high to denature double-stranded DNA. The denatured DNA is maintained in a single-stranded state and migrates through the alkaline gel as a function of its size. Alkaline agarose gels are used chiefly to measure the size of first and second strands of cDNA (Construction of cDNA Libraries Stage 1: Synthesis of First-strand c...

Fluorescence two-dimensional difference gel electrophoresis for biomaterial applications.

Fluorescence two-dimensional difference gel electrophoresis (DiGE) is rapidly becoming established as a powerful technique for the characterization of differences in protein expression levels between two or more conditions. In this review, we consider the application of DiGE-both minimal and saturation labelling-to biomaterials research, considering the challenges and rewards of this approach.
