Accelerating Drug Discovery: Tsingke Biotech Unveils Next-Generation Rapid Protein and Antibody Solutions

BEIJING and LISBON, Portugal, Nov. 19, 2025 /PRNewswire/ -- At PEGS Europe 2025, one of the industry's premier gatherings for innovation in protein and antibody engineering, Tsingke Biotech highlighted its latest accelerated protein and antibody services. The leading Chinese biotechnology company announced that its services can generate proteins in as little as 3 days and produce antibodies within 7 days, offering a potential step-change in speed for biopharma developers aiming to shorten drug discovery timelines worldwide.

High-Speed Protein Production Across Six Expression Systems

Tsingke Biotech combines advanced gene synthesis, automated expression, and purification technologies to deliver rapid protein production. The company supports six expression systems—including E. coli, Bacillus subtilis, yeast, insect, mammalian, and cell-free systems—allowing simple proteins to be produced in 3 days via cell-free methods, while complex proteins and antibodies are ready in 7–14 days. According to Tsingke, overall protein expression success reaches 95%.

Accelerated Antibody Discovery and Production

Traditional hybridoma-based antibody development can take 1–2 months. Tsingke's Single-B Cell Antibody Discovery Service preserves natural VH/VL pairing and generates high-affinity antibodies (10⁻⁸–10⁻¹² M), utilizing FACS technology. The service is engineered for efficiency, delivering full, comprehensive results in a remarkable timeframe of just 8–10 weeks. Furthermore, the supported formats encompass a broad spectrum of therapeutic antibodies sourced from both mouse and rabbit models, ensuring versatility for critical research and development needs.

In addition, for antibody production, Tsingke uses Expi293 and CHO-K1 systems, achieving milligram-scale yields in 7 days and gram-scale yields in 14 days, with average production exceeding 300 mg/L. A broad range of antibody formats, including VHH-His and VHH-Fc, are available.
