Pharmaceutical biology·2023

Quality control methods for recombinant human endostatin were established using bioassays and analytical techniques. These methods ensure the consistent quality and purity of endostatin drug substances for therapeutic use.

Area of Science:

Biotechnology
Protein Chemistry
Pharmacology

Context:

Recombinant human endostatin is a critical therapeutic agent.
Ensuring the quality of biological products is paramount for patient safety and efficacy.
Existing quality control methods required standardization for recombinant endostatin.

Purpose:

To develop and validate robust quality control methods for recombinant human endostatin.
To establish assays for biological activity, purity, and identity.
To meet national regulatory standards for biological products.

Summary:

Biological activity was assessed via endothelial cell migration assays.
Peptide mapping confirmed identity, while SDS-PAGE and RP-HPLC demonstrated high purity (>99%).
