Denaturing and non-denaturing microsolution isoelectric focussing to mine the metalloproteome.
Metals bound to proteins play essential roles in living systems. Elements such as phosphorus, selenium and iodine are commonly covalently linked to proteins while others are non-covalently complexed. Thus, the identification and characterization of the metal-protein complexes require a careful hyphenation of techniques able to separate and detect the intact binding complexes with both high reso...
متن کاملIsolation of the two monoferric human transferrins by preparative isoelectric focussing.
1. Human transferrin was labelled with Fe(III) in nitrilo triacetate buffer at one of its two metal binding sites by variation of the pH. The A-site was preferentially labelled at pH 7.2, the B-site at pH 9.2. 2. The monoferric transferrin preparations were subjected to preparative isoelectric focussing, isolated from the granulated gels, and checked for homogeneity and purity on an analytical ...
متن کاملDifferential Human plasma proteomics Based on AniBal Quantification and Peptide-level Off-Gel Isoelectric Focussing
Despite its enormous complexity, human plasma is still one of the most frequently used body fluids for identification and quantification of health and disease biomarkers. We have developed a new workflow for qualitative and quantitative analysis of human plasma proteins. The first step was to remove the seven most abundant plasma proteins (MARS). Moreover, in order to reduce the complexity of t...
متن کاملFocussing and proof construction
This paper proposes a synthetic presentation of the Proof Construction paradigm, which underlies most of the research and development in the so-called “logic programming” area. Two essential aspects of this paradigm are discussed here: true nondeterminism et partial information. A new formulation of Focussing, the basic property used to deal with non-determinism in proof construction, is presen...
متن کاملFocussing on Extra-Ordinary Users
“Universal Access” is often focused on modifying main-stream products to respond to the demands of older and disabled people – which implies an extremely wide range of user characteristics. “Accessible” system design can produce systems which may be “accessible” but are in no sense “usable”. Many system developers also seem to believe that a consideration of older and disabled people mean the a...
