The effect of sequence truncation and amino-acid substitutions on the biophysical properties of protein S and calbindin D9k.

Popular Abstract in Swedish Proteiner är helt nödvändiga för alla former av liv på jorden. En typisk cell består till 50-60 % av proteiner, om man bortser från vatten. Det är ett protein, hemoglobin, som transporterar syre från lungorna till kroppens celler och ger blodet dess röda färg. Det är ett protein, alfa- keratin, som bygger upp vårt hår och våra naglar. Det är två proteiner, aktin och myoProtein S is a modular protein and a cofactor in the protein C anticoagulant system. It consists of a Gla-module, a thrombin-sensitive loop, four EGF-modules and a SHBG-like module. Protein S has previously been shown to contain four binding sites with high affinities for Ca2+ (Ka>9x105 M-1 at physiological ionic strength) and at least one of the sites h

Quality Control for high-throughput Quantitative Proteomics - Harnessing the potential of label-free LC-MS

Popular Abstract in Swedish Sedan kartläggningen av det mänskliga genomet, har mer fokus lagts på dess produkt, proteomet, som definieras som de proteiner som uttrycks i en cell vid en viss tidpunkt. Proteomets dynamiska egenskaper gör det till en fantastisk källa för så kallade biomarkörer, det vill säga molekyler som genom deras koncentrationsmönster kan användas för att särskilja sjuka och frisMultiplex protein quantification, proteomics, is essential for uncovering new biomarkers and understanding biology. Liquid chromatography coupled to mass spectrometry (LC-MS) is the predominant technique for these measurements. In this thesis, optimization and quality control strategies for different phases of the LC-MS pipeline have been developed. Due to the inherent complexity and dynamic rang

Fragments of home in youth care institutions

A youth care institution may seem like a sort of regulated home. It does not resemble a home in the sense of a private household, and the youth living there usually do not define it as a home, but it seems like a home in the sense of being a place where youth in treatment spend most of their days and nights. But is that what a home is? In many cases, people in modern societies are not supposed to
