Antibody Drug Excipient Detection

Antibody drugs, as a type of therapeutic biological preparation, require not only precise bioengineering techniques for their production but also rely on a variety of raw materials and ancillary materials to support the production and stability of the drugs. These materials include but are not limited to amino acids, sugars, protein stabilizers, buffers, surfactants, etc. They play an indispensable role in ensuring the efficiency of cell culture processes, the purity of antibody drugs, and the quality of the final formulation. Considering that these raw materials may come from a variety of suppliers and contain substances with various chemical and biological properties, strict testing and evaluation of each substance is a necessary step to ensure the quality and safety of antibody drugs. Impurities and variability in raw materials may have a negative impact on the drug production process, and even pose a risk to patient safety.

 

The testing of raw materials occupies an important position in the production of antibody drugs. The goal is to ensure that all input raw materials meet established quality standards and specifications. These tests include evaluations of physical and chemical properties, such as pH, solubility, ionic strength and molecular weight distribution, etc.; biological property evaluations, such as endotoxin and microbial contamination levels; and functional tests, such as the impact on the stability of the final drug product. High Performance Liquid Chromatography (HPLC), Gas Chromatography (GC), Mass Spectrometry (MS) etc. are the main methods used for raw material analysis. These methods can effectively analyze the types and contents of various raw materials in vaccines to ensure the quality and safety of vaccines. For example, HPLC can be used to analyze adjuvants and stabilizers in vaccines, while MS can be used to analyze trace elements and potential impurities in vaccines. Through these methods, we can fully understand the quality of the vaccine and the effects it may have on the human body.
