Capillary electrophoresis of peptides. Analysis of adrenocorticotropic hormone-related fragments.
نویسندگان
چکیده
Capillary electrophoresis can be used successfully to analyse small peptides to give additional information to that obtained using high-performance liquid chromatography (HPLC). The separation of a modified adrenocorticotropic hormone (4-9) fragment (Org 2766) and several of its fragments was investigated using capillary zone electrophoresis. Prediction of migration in aqueous systems using pKa-related data and the migration behaviour using sodium dodecyl sulphate in the buffer are discussed, as is the choice of buffer systems. The electrophoretic patterns are compared with the HPLC separation.

Two Capillary Zone electrophoresis (CZE) methods were developed in this study, one using an acidic buffer (sodium citrate pH = 2.5) and the other using a basic buffer (sodium tetraborate pH = 9.8). The two methods were compared on the basis of repeatability and reproducibility of results and the CZE method developed with the basic buffer was then selected for further studies. The method was ful...

Isolation of cell free fetal DNA (cffDNA) from maternal serum usually leads to very low concentrations of DNA impeding further resolving through conventional methods of electrophoresis. Although several protocols have been described for capillary electrophoresis (CE) of double stranded DNA, they usually need using special polymers or coated capillaries which degrade over time. Herein, we propos...

Combination of standard approaches like pepsin digestion and slab gel electrophoresis with capillary separations allows a relatively easy identification of in vivo occurring collagen fragments. Capillary electrophoresis can be done either in 25 mM phosphate buffer (pH 2.5) or in a 25 mM phosphate buffer (pH 4.5) made 0.1% with respect to sodium dodecyl sulfate (SDS). While in the first case pep...
متن کاملDifferential expression of two pro-opiomelanocortin mRNAs during temperature stress in common carp (Cyprinus carpio L.).
Pro-opiomelanocortin (POMC) is the precursor of a number of biologically active peptides, including adrenocorticotropic hormone, alpha-melanocyte-stimulating hormone and beta-endorphin, which are released by the pituitary glands of fish as well as mammals. To quantify the levels of expression of the two POMC mRNAs relative to one another during the response of the common carp to temperature-ind...
