1. 1. Microfluidic electrocapture technology in protein and peptide analysis

   Författare :Juan Astorga-Wells; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   Sammanfattning : After sequencing the genomes of several organisms, science in the postgenomic era now aims at a thorough study of the proteins present in a given tissue or organism. Since this task requires an enormous analytical effort, integrated microfluidic systems are envisioned as the solution to automated high throughput analysis of biomolecules. LÄS MER

3. 2. Novel clean-up, concentration and laser desorption/ionization strategies for mass spectrometry

   Författare :Mohammadreza Shariatgorji; Leopold Ilag; Juan Astorga-wells; Bernhard Spengler; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Mass spectrometry; ESI-MS; SALDI-MS; Electrocapture; Sample treatment; Analytical chemistry; Analytisk kemi; Analytical Chemistry; analytisk kemi;

   Sammanfattning : Despite valuable advantages of mass spectrometry (MS) techniques they still have drawbacks that need to be overcome, notably their sensitivity to various kinds of interfering substances and associated difficulties involved in detecting signals from analytes present in trace quantities. Thus, high quality analytical data could be acquired by improving sample pre-treatment techniques and/or ionization methods to increase ionization yields and/or avoid the generation of unwanted ions.
