Agilent's Solution for On-Line 2D Nano LC/MS
 On-line 2D Nano LC/MS is well suited for digests from gel spots or bands which need further separation and for subcellular proteome fractions of higher complexity. It is also useful for identifying biomarkers in pre-enriched biological fluids like blood, spinal fluid or urine And it is the best choice for further separation of affinity-purified post-translationally modified (PTM) peptides or protein complexes for functional proteomics research. Here, Agilent offers a flexible approach which is based on the Agilent Nanoflow Proteomics Solution.
