Substantial contract for Proteome Sciences

Proteome Sciences (AIM:PRM), is pleased to announce that the Company has secured a contract win from a US biopharmaceutical company using the Company's mass spectrometry services for the analysis of samples for an on-going clinical trial. This project will be provided utilising the Good Clinical Laboratory Practice ("GCLP") accreditation obtained by Proteome Sciences specifically for this type of project. The contract value is in excess of £500,000 and the Company considers that a good proportion of the work should be completed in this financial year.

Commenting on the contract, Richard Dennis, Chief Commercial Officer of Proteome Sciences said:

"We have experienced good customer interest in our services in the first Quarter reflected by the considerable increase in customer contact and quotations across a broad range of projects. In this contract the client selected our targeted assay workflows with GCLP compliance as a quality standard specifically to monitor the performance of their investigational drug in their clinical trial.  We expect the increased levels of interest in our services activities to continue through 2024 and look forward to further clinical trial projects."
