  33. PROTEOMICS TODAY BY 2-DIMENSIONAL LC/ MS/MS MudPIT: Multidimensional Protein Identification Technology Typically identifies 2.5-3 peptides per protein; rugged method. Good where sample size is limited ADVANTAGES OVER 2-D ELECTROPHOPHORESIS 1) Greater dynamic range: Most abundant protein detected Least abundant protein detected 2) Works better for hydrophobic and very basic proteins 3) Handling and automation easier - from Link et al., Nat. Biotechnol. 17 (1999) 676-682 -

ACCEPTABLE Identifying proteins via 2 peptides or more

  36. UFFLC of Intact Proteins Solves the Problem & Increases Detection of Low Abundance Proteins Low-abundance Protein X is 0.1% of total protein 1 2 3 4 5 6 7 8 9 10 Now Protein X is 1.0 % of total protein in Fraction #6. After digestion, its peptides will be 10x higher a percentage of the total in that fraction than would have been true in a digest of the unfractionated mixture. That greatly increases the chances of identifying Protein X through 2-3 of its fragments rather than just one.

  39. Advantages • See lower abundance proteins • Compare MS of intact proteins to proteins found by bottom up method • Allows further analysis of fractions of interest • High speed allows multiple runs to be set up giving higher utilization of the MS • Reduces number of One Hit Wonders

  40. UHP UFFLC • Higher throughput than any other system • Allows use of standard columns and UHP columns • Allows normal chromatography and small scale prep as well as UHP &UFFLC • Highest pressure and flow limits on the market today. Why limit yourself
