Microfluidic device for cell counting and electrical lysis
Václavek, Tomáš ; Křenková, Jana ; Foret, František
This lecture presents two microfluidic devices as essential units for single cell proteomic analysis, firstly a device for cell counting based on resistive pulse sensing as an alternative to optical platforms based on visual control over the sample input, secondly a unit for electrical lysis of cells using direct current voltage pulses to lyse cells one by one with a possibility to analyze the distinct lysate zones by electrospray ionization mass spectrometry.
The study of cadmium - oxalic acid complexes using DPASV and ESI-MS
Jakl, M. ; Jaklová Dytrtová, Jana ; Tlustoš, P.
The combination of DPASV with ESI-MS allows a reliable detection of metal complexes with small organic ligands. The request to exact molecular mass is essential to stoichiometry design simultaneously with low concentration of the analyte in most of biological matrixes. By the analysis of model solution consisting of Cd(NO3)(2) and oxalic acid (OAH(2)) these structures were identified: [Cd(OAH(2))(H2O)(2)](+), [Cd(OAH(2))(H2O)(3)](+), and [Cd(OAH(2))(H2O)(2)(CH3OH)](+). They were also found in soil solution.
