Protein MS
Protein LC/MS Analysis Services
| Features and Benefits of Novatia Protein LC/MS Services | Applications |
- Excellent mass accuracy, nominal mass ± 0.01% (i.e., 1 Da in 10 kDa) and exact mass ± 0.0005% (i.e., 0.05 Da in 10 kDa)
- Mass resolution better than MALDI, particularly for large proteins (>20 kDa)
- Applicable to large proteins, including intact antibodies
- Methods for detailed profiling and/or high-throughput MW determination are available.
- Chromatographic separation often reveals components not seen by MALDI or direct injection ESI.
- Unparalleled ProMass ESI spectral deconvolution technology
- Our system can analyze proteins in high concentrations of salts, buffers, or other contaminants.
- Backed by over 38 years experience in biological mass spectrometry
- We also specialize in oligonucleotide characterization.
