5 Sample Preparation for Peptide Mapping A time consuming, labor-intensive process to do manually, with multiple steps that can be optimized. Sample Preparation Depletion of matrix proteins, enrichment of target protein, dialysis or desalting Reduce disulfide bonds, and block to prevent re-formation Denaturation, Reduction, & Alkylation Digestion Trypsin is the most common digestion enzyme, but others may be called for depending on the protein and experiment. Sample concentration, enrichment for specific PTMs, or desalting Enrichment & Cleanup 5

8 General Considerations for Peptide Mapping Column Selection Instrument capabilities and requirements - UV vs MS detection or both - Pressure capabilities Mobile phase requirements - High ph required for sample - TFA vs Formic acid Sample - Hydrophilic vs hydrophobic peptides - Larger polypeptides present Column dimensions - Generally prefer longer columns, especially for more complicated maps - 5, 5, and 25 mm lengths available - Use 2. mm i.d. for MS-sensitivity - 3. and 4.6 mm i.d. also available - Smaller pore sizes ideal, usually -5 Å 8
9 Detectors for Peptide Mapping UV Often used in routine process measurements, QA/QC labs No peptide mass or structural information; relies on reproducibility of RT, peak area, and peak area ratios Traditionally uses TFA modifier MS Often used in discovery/early development stage, R&D labs MW and structural information (MS/MS) to assist with co-elution challenges, verify sequence coverage, and to ID unknown peaks when they appear Generally prefer formic acid modifier to avoid ion suppression from TFA 9
10 Mobile Phases for Peptide Mapping Ion pairing agents used for RP LC Increase retention of small, poorly retained peptides Block exposed silanol sites on silica-based columns Acid helps solubilize and ionize peptide and protein samples TFA works well on traditional silicabased columns, but formic acid does not Formic acid produces broad, asymmetric peaks Poor resolution and poor peak capacity Need column solution for formic acid modifier AdvanceBio Peptide Plus Charged surface chemistry solves the problems associated with formic acid

36 Separation of Deamidated Peptides VVSVLTVLHQDWLnGK or VVSVLTVLHqDWLNGK m/z , doubly charged peptide Traditional silica columns don t resolve deamidation as well as charged surface columns. Traditional Silica Column AdvanceBio Peptide Plus Determination of deamidated peptides is an important goal of peptide mapping. Chromatographic resolution is important. MS/MS confirms which peak corresponds to which deamidation site. AdvanceBio Peptide Plus enhances analysis because it has higher selectivity for deamidated forms of peptide over the normal form.
37 Choosing a Column Chemistry For LC/MS work, AdvanceBio Peptide Plus with formic acid is the first choice. Best peak shape with formic acid, high peak capacity, high mass load tolerance, excellent PTM resolution (especially deamidation), peak shape and recovery of hydrophobic peptides, unique selectivity Exception : Sample is especially rich in small, hydrophilic peptides. Poor retention of small, hydrophilic peptides is a feature common to charged surface columns. In this case, try AdvanceBio Peptide Mapping or Eclipse Plus C8 first. Exception 2: Different selectivity is needed to separate a key pair. Charged surface chemistry AdvanceBio Peptide Plus vs Regular silica chemistry AdvanceBio Peptide Mapping Eclipse Plus RRHD ZORBAX 3 37
38 Choosing a Column Chemistry Sample Detection First Choice of column Alternative column Peptides LC/MS (FA) AdvanceBio Peptide Plus AdvanceBio Peptide Mapping LC/UV AdvanceBio Peptide Mapping AdvanceBio Peptide Plus ZORABX RRHD 3SB-C8 or Diphenyl For maximum flexibility to transfer methods across instrument platforms, use AdvanceBio Peptide Plus with formic acid. 38
39 Method Development Tips & Reminders Bonded Phase: C8 is routinely used. Try AdvanceBio Peptide Plus first; for alternate selectivity or highly hydrophilic samples try AdvanceBio Peptide Mapping or a ZORBAX column. Column dimension: Good start with 2.mm 5mm, for higher resolution use longer column Gradient: Acetonitrile : Water with.% formic acid, other organic solvent substitutions can be used for different selectivity Starting gradient time: -4% in 3min (.3%/min) Temperature: Higher column temperature can dramatically improve both resolution and recovery (6 C max) Desalt peptide mixture prior to injection Sample handling may cause artifacts (peptide modifications) 39
40 Troubleshooting Reasons for < % Sequence Coverage Question to ask: Looking at the protein sequence, what s missing? Very small and/or very hydrophilic peptides? If using AdvanceBio Peptide Plus, try AdvanceBio Peptide Mapping for better retention and/or resolution. Very large and/or very hydrophobic peptides? Can you go to a higher percent organic mobile phase? Are peptides sticking to sample tubes or otherwise lost during sample preparation? Or on the LC? If using AdvanceBio Peptide Mapping, try AdvanceBio Peptide Plus - May even need to consider a C8 column rather than C8 Very large, or very small peptides of any hydrophobicity? Consider a different digestion enzyme 4
