This in-solution electrophoretic device is for the partitioning of μL volumes of μg-mg amounts of proteins and or peptides based on surface charge, pH, size in denaturing or native formats.
It is typically used to partition contaminant proteins away from lower abundance proteins (eg. Albumin or Ig from other plasma proteins), desalting of biological samples (eg. urine, plasma, tears), enrichment of poorly concentrated and low abundance samples for further analysis. Partitioning down to 1 kDa is achievable and is therefore ideal for peptide and small protein work.
