HPLC and LC-MS
Purity is commonly reported from HPLC chromatograms. Molecular weight is confirmed by mass spectrometry or LC-MS. Additional methods can be requested for specific research programs.
Modification chemistry
Labeling, cyclization and conjugation should be planned with the synthesis route. Spacer length, dye selection and conjugation site all influence assay performance.
Documentation
Research projects are supplied with quality documentation appropriate to the requested grade. Materials remain designated for research use only.
