About

The Protein Production Core Facility (PPCF) is designed to provide users with the complete infrastructure for protein production using the most modern and efficient methods. Particular attention is paid to maintaining the highest quality standards of the samples to be produced, which guarantees the suitability of the samples for functional and structural studies in a reproducible manner. Additionally, we aim to develop sustainable processes.

Research

The PP facility is involved in the following research projects:

In-solution inhibition studies of SARS-CoV-2 3C-like main protease
As an extension of the crystallographic studies that Alke Meens at al. performed on DESY Campus, Cy Jeffries from the EMBL SAXS group (Dmitri Svergun) performs further extensive in-solution inhibition studies of the SARS-CoV-2 3C-like main protease using SAXS. The required proteins, including the SARS-CoV-2 3C-like main protease, is produced by the PPCF.

Serological test for COVID 19 Description:
Our collaboration partner, the DDM (Diagnostics Development Laboratory) group at the BNI, has a longstanding expertise in the development of ELISA-based serological test being highly specific to distinguish between homologous viral subtypes. For the development of such subtype-specific Sars-Cov2 ELISA-based serological test the PPCF produces a variety of proteins and optimizes their formulation.
