What is the concentration of BSA I should use as a carrier in peptide/protein dilution for LC-MS/MS?

The peptides I'm working with are very likely to attach on the wall of the vial I'm using for LC-MS/MS. I saw many people suggested to use 2-3% BSA as carrier in the solvent for peptide/protein...

Can anyone give an explanation on these EIS results? Glassy carbon (GC) and CNT modified GC electrodes were used.

I did CV and EIS on both GC and CNT modified GC electrode in 5 mM equal molar Ferri-Ferro (1M Na2SO4). The CV results showed that CNT improved the peak current while maintained the peak separation...

How is the reproducibility of experiments in electrochemical impedance spectroscopy (EIS)?

It puzzles me when I try to repeat EIS experiments. The same experimental conditions are used, unless the bare electrode is cleaned between each run. Different EIS data is obtained in terms of the...

Can anyone give an explanation of the causes of a strange high frequency response in electrochemical impedance spectroscopy?

I use bare Au or Pt electrode as the working electrode. Ag/AgCl and Pt wire are the reference and counter electrode, respectively. 1 M KNO3 is chosen as the electrolyte. Open circuit potential is...
