Custom HPLC Peptide Synthesis Analysis Services

Description: High Performance Liquid Chromatography is an analytical technique for separating compounds in a sample matrix. Separation is achieved by dissolving the sample in a suitable solvent and injecting it into a stream of solvent called the mobile phase. The mobile phase (and injected sample) is passed through a stationary phase (HPLC column). The compounds exit the column at different times based on the affinity the compounds have for the mobile phase and the

Custom MS LC-MS Peptide Analysis Services

Description: Using peptide mapping, subtle changes to the primary structure of a protein or antibody can be identified that may affect the activity of the protein or the binding affinity. Peptide mapping by LC-MS/MS is one of the most powerful qualitative assays to confirm the primary sequence of proteins or antibodies. This service can be used to compare different lots of the same proteins, antibodies or biosimilars. Service of peptide mapping analysis by LC-MS/MS includes:

Peptide Impurity Profiling Service - KS-V Peptide

Peptide Impurity Profiling Service Presence of an impurity can be a real issue in drug development. It can considerably lengthen and complicate development times if not characterized in time and incur considerable extra-costs. Sometimes the entire formulation has to be reviewed. Thats why impurity profiling analysis is an important step in drug development and drug storage. An impurity is defined as an unwanted compound remaining in a drug formulation other than the active

Exendin-4 (9-39) Diabetes Peptides CAS 133514-43-9 Catalog Number KS031013

Exendin-4 (9-39) CAS 133514-43-9 Catalog Number KS031013 This truncated Exendin-4 peptide, Exendin (9-39) amide, is a potent Glucagon-Like Peptide 1 (GLP-1) receptor antagonist. Unlike the full length Exendin-4 (a GLP-1 agonist), Exendin (9-39) antagonizes GLP-1stimulated insulin release after food intake. It is a competitive inhibitor of Exendin-3 and Exendin-4.
