AdvanceBio Peptide Mapping

AdvanceBio Peptide Mapping Guard Columns from Agilent Technologies

Choosing to use guard columns can help reduce operating expenses, by reducing the frequency of analytical column replacement. The guard column prevents damage caused by particulate matter and strongly adsorbed material. To maintain an adequate capacity for sample impurities, choose a guard column with an internal diameter similar to the column internal diameter. Ideally, the packing of the guard column should be the same as the analytical column so that the chromatography of the analytical column is not altered.

Agilent AdvanceBio Peptide Mapping columns are designed to provide high- resolution peptide maps for protein identification and determination of post translation modifications. These columns provide the ability for you to quickly resolve and identify amino acid substitutions/modifications in a protein primary sequence. These advanced biocolumns are superficially porous and have a 120Å pore size which is optimum for the analysis of the peptides produced by enzymatic digest of proteins.
