Analysis, by two-dimensional gel electrophoresis, of ribosome crystal proteins

Two-dimensional Gel Electrophoresis

Analysis of triplet repeat replication by two-dimensional gel electrophoresis.

Expansions of triplet repeats are responsible for more than 15 hereditary neurological disorders in humans. Triplet repeats are fairly stable when the number of elementary units is under approx 30, but become polymorphic in length with a clear bias for expansions when this threshold is exceeded. This results in the rapid addition of hundreds or even thousands of extra repeats and, ultimately, d...

Identification by Two-Dimensional Gel Electrophoresis

We have previously identified proteins in fractions of culture filtrate ofMycobacterium tuberculosis with the capacity to induce cytokine production in monocytes, by using a technique we defined as "monocyte Western blotting" (immunoblotting). In this series of experiments, we have extended this technique to two-dimensional gel electrophoresis and have identified a novel 58-kDa protein ofM. tub...

Analysis of the cytosolic proteins of chick embryo gonads by two-dimensional gel electrophoresis.

Gonads and mesonephros dissected from normal chick embryos, as well as a blood sample, were labelled in vitro with [35S]methionine and [14C]leucine. The patterns of cytosolic protein synthesis of the different tissues were analysed using two-dimensional (2-D) polyacrylamide gel electrophoresis. Three developmental stages, i.e. 8, 12 and 17 days of incubation, were investigated. Five sex-specifi...

Two-dimensional gel electrophoresis and immunoblotting of Campylobacter pylori proteins.

Whole-cell, outer-membrane protein, flagellum-associated antigens and partially purified urease of Campylobacter pylori were analyzed by two-dimensional gel electrophoresis. C. pylori strains were readily distinguished from strains of Campylobacter jejuni, C. coli, and C. fetus by absence of major outer membrane proteins with Mrs of 41,000 to 45,000. C. pylori strains also lacked the acidic sur...
