Monoclonal Antibody Characterization Service

Monoclonal antibody (mAbs) drugs have been widely used in autoimmunity, tumors, transplant rejection, viral infections and other diseases due to their advantages of high specificity, good uniformity, high sensitivity, and mass production. Monoclonal antibody drugs occupy an increasing share of the biopharmaceutical market. More and more companies have joined the production of monoclonal antibody drugs. In order to ensure the safety and effectiveness of monoclonal antibody drug products and promote orderly and benign R&D and competition in this field, relevant regulatory authorities continue to put forward new requirements for the characterization, analysis and quality control of monoclonal antibody biotherapeutics.

Amino Acid Analysis Service

Monoclonal antibody drugs require in-depth characterization to obtain approval for clinical trials and subsequent sales. The current quality standards of monoclonal antibody drugs mainly refer to the relevant technical guidelines of International Conference on Harmonization of Registration Pharmaceuticals for Human Use (ICH), Food and Drug Administration (FDA), United States Pharmacopoeia (USP) and European Pharmacopoeia (EP).

The inspection items can be divided into:

1) General inspection, such as appearance, color, turbidity, visible foreign matter, etc.;

2) Physical and chemical inspection, such as moisture, pH, osmotic pressure, extinction coefficient, insoluble particles, etc.;

3) Purity and impurity analysis, such as protein purity determination, molecular size variants, charge variants, product-related impurities, process-related impurities;

4) Content determination, such as protein content determination;

5) Identification and consistency analysis, such as analysis based on molecular structure and (or) other unique attributes;

6) Potency analysis, such as biological activity and binding activity.
