Polysialic acid (polySia) is a carbohydrate polymer of varying chain length. It is a promising scaffold material for tissue engineering. In this work, high chain length polySia was produced by an Escherichia coli K1 strain ...

This study describes the purification of penicillin G amidase (PGA) by ion exchange membrane adsorbers in a one-step-process. Preliminary experiments with high-throughput screening devices in microliter scale (8-strip ...

Polysialic acid (polySia) is a promising molecule for various medical applications (e.g., treatment of inflammatory neurodegenerative diseases). In this study a complete production process for human-identical α-(2,8)-linked ...
