   Författare :Tove Boström; Sophia Hober; Thomas Laurell; Ole N. Jensen; KTH; []
   Nyckelord :Proteomics; mass spectrometry; affinity proteomics; immunoenrichment; immunoprecipitation; IMAC; screening; protein production; protein purification; ISET; quantification; SILAC; stable isotope standard; antibody validation; Bioteknologi; Biotechnology;

   Sammanfattning : In the field of proteomics, proteins are analyzed and quantified in high numbers. Protein analysis is of great importance and can for example generate information regarding protein function and involvement in disease. Different strategies for protein analysis and quan- tification have emerged, suitable for different applications. LÄS MER

3. 2. Quantification Methods for Clinical Studies in Nuclear Medicine - Applications in AMS, PET/CT and SPECT/CT

   Författare :Marie Sydoff; Malmö Medicinsk strålningsfysik; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Nuclear Medicine; AMS; PET CT; SPECT CT; dosimetry; internal dosimetry; quantification; activity quantification; volume delineation; radiation; biokinetics; pharmacokinetics; biodistribution;

   Sammanfattning : An essential part of the development of new radiopharmaceuticals for use in diagnostic nuclear medicine is the determination of its biokinetic properties. The uptake and turn-over of the radiopharmaceutical in the source organs is of great interest since this could determine whether the radiopharmaceutical would be suitable for clinical use or not.

4. 3. Towards specific quantification of exosomes using surface-based sensing

   Författare :Deborah Rupert; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; label-free; surface plasmon resonance.; exosome; binding rate; antibody; concentration; nanoparticle tracking analysis; quantification; liposome; cluster of differentiation 63 CD63 ; diffusion; specific detection; mass transport limited conditions; extracellular vesicles; surface-based biosensor;

   Sammanfattning : When exosomes were first observed in 1967, they were believed to be cell debris until extensive studies demonstrated key biological functionalities related to their composition and formation mechanism. Exosomes are nanometer-sized lipid vesicles of endocytic origin, with a membrane consisting of lipids and proteins and encapsulating a cargo composed of soluble proteins and genetic material.

7. 5. Advances for Biomarker Discovery in Neuroproteomics using Mass Spectrometry : From Method Development to Clinical Application

   Författare :Marcus O.D. Sjödin; Magnus Wetterhall; Jonas Bergquist; Dominic M. Desiderio; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Mass Spectrometry; Biomarker; Proteomics; Central Nervous System; Cerebrospinal Fluid; Traumatic Brain Injury; Cloud-Point Extraction; Neuroproteomics; Relative Quantification; Spinal Cord Stimulation; Neuropathic Pain; Analytical Chemistry; Analytisk kemi;

   Sammanfattning : Proteins offer a prominent group of compounds which may be ubiquitously affected in disease and used as biomarkers for early diagnosis, assessing treatment or drug development. Clinical proteomics aim to screen for protein biomarkers by a comprehensive analysis of all proteins expressed in a biological matrix during a certain pathology. LÄS MER
