proteomics

Question 1

what is two-dimensional gel electrophoresis (2DE)?

Answer 1

a gel-based method which separates proteins based on isoelectric focusing point and molecular weight

Question 2

what is multi-dimensional liquid chromatography (MDLC)?

Answer 2

a column based method which uses two different columns that separate proteins based on two different physical characteristics (e.g. molecular weight and charge)
