The task of accurately separating, identifying, and quantitating amino acids in the research, development, and commercialization of food, feed, and biotherapeutic products is challenging. To analyze released amino acids by HPLC or UPLC, Waters provides many solutions that use pre-column derivatization so that amino acids can be analyzed by optical detection.

Adequate endotoxin testing is invaluable in ensuring quality and safety. LAL assays require cumbersome sample preparation and are easily disturbed by different constituents of the sample. EndoLISA, combining solid-phase format and synthetic rFC, achieves sensitive detection of endotoxin by eliminating interfering components. It can be automated, which accelerates the test with minimal human error.

N-glycans affect the safety and efficacy of many therapeutic proteins and are routinely monitored for the quality of biotherapeutics. Here, we present a complementary method for analyzing the complex N-glycans released from human chorionic gonadotrophin (hCG). The automated method provides a reproducible glycan profile and is suitable for commercial as well as research environments.
