As antibody therapeutics evolve, new formats such as bispecific antibodies (bsAbs) and Fab fragments offer new and exciting therapeutic opportunities. However, traditional mAb isolation methods are often ineffective, necessitating innovative solutions. This article explores these challenges and introduces Astrea Bioseparations’ Fabsorbent™ F1P HF as an alternative strategy for isolating next-generation antibodies. Gain insights into:

- **The rise of new antibody formats**: How advances in antibody engineering have led to bispecific antibodies and Fab fragments, expanding drug discovery possibilities.
- **Overcoming purification challenges**: Why traditional mAb methods like Protein A chromatography fall short for newer antibody formats and what alternative strategies exist.
- **Optimising downstream processing**: How Astrea Bioseparations’ Fabsorbent™ F1P HF provides a robust, cost-effective solution to Protein L for antibody fragment capture.
