Request a free sample submission kit, complete with instructions, sample collection tubes and a pre-paid FedEx mailer to ship your samples to us. Results are returned in about one week.

Catalog No. Instrument LC-MS/MS Gradient Time Cost
121 LTQ Velos 30 min $100
123 Q-Exactive 30 min $200

Protein Identification and Characterization for Non-Gel Samples

Mass spectrometry-based proteomic profiling and analysis of samples in non-gel formats. Quantitative analyses are not included in these items (see Global Proteomic Profiling below, for quantitative assays).

Catalog No. Instrument LC-MS/MS Gradient Time Cost
131 LTQ Velos 30 min $150
133 Q-Exactive 30 min $250

Protein Mapping

Mass spectrometry-based multi-enzyme proteomic profiling and analysis of a purified protein such as a therapeutic antibody or any relatively pure protein. The target protein is enzymatically digested with trypsin, chymotrypsin and elastase to maximize sequence coverage. On the LTQ Velos each digestion is analyzed by a separate LC-MS/MS assay. On the Q-Exactive the high mass accuracy and high resolution measurements allow the digestion products to be mixed and analyzed in a single LC-MS/MS assay.

141 LTQ Velos 3x 30 min $500
142 Q-Exactive 30 min $500

De Novo Protein Assembly

Sequence a purified protein with no reference sequence required. Multiple enzymes are used to create overlapping fragments along the length of the protein sequence. Each fragment is characterized de novo via tandem mass spectrometry on a Q-Exactive. The de novo sequences are then assembled into a full length protein sequence. This assembled sequence is validated using standard digestion and LC-MS/MS sequencing approaches to confirm the finding. we can generally obtain over 90% sequence coverage.

Global Proteomic Profiling, $1000 Proteome

Mass spectrometry-based global, unbiased shotgun proteomic profiling and analysis to generate identifications and relative quantities for thousands of proteins.

Targeted Proteomic Assays

Targeted assays are performed on a Q-Exactive quadrupole-Orbitrap mass spectrometer using high resolution and accurate mass scans for sensitive, specific, reproducible quantitation. Two quantitation modes are available. Multiplexed single ion monitoring (SIM) achieves the highest levels of sensitivity and is appropriate for analyte targets present in a low- to medium-complexity background. Parallel reaction monitoring (PRM) fragments target analytes via HCD and quantifies based on the peak areas measured from the fragment ion intensities. Measurement of fragment ions improves specificity and enables measurement of target analytes in high complexity matrices.

Assays may be run label-free to generate relative quantitative measurements or against stable isotope labeled peptides to generate absolute quantitative measurements. Please inquire for pricing.
