MALDI-TOF for Precise and Fast Microorganism Identification in Compliance with Updated EudraLex Annex 1
Tentamus Pharma UK, a GMP laboratory, introduces MALDI-TOF. This cutting-edge instrument plays a crucial role in the rapid and precise identification of microorganisms in pharmaceuticals and medical devices.
What is MALDI-TOF?
MALDI-TOF stands for Matrix-assisted Laser Desorption/Ionisation Time of Flight, a mass spectrometer capable of identifying microorganisms at the species level.
It uses an ultraviolet laser to irradiate samples embedded in a matrix, inducing the acceleration of proteins and peptides. This acceleration enables them to travel towards the detector at a speed dependent on their mass.
Given that proteins and peptides have distinct masses, they reach the detector at different times. Subsequently, this speed is translated into an exact molecular mass, which is then compared with an internal database of microorganisms.
The MALDI-TOF can allow quick turnaround times, it has the capacity to test up to 95 samples per plate, with the capability of testing more than one plate per day, covering organisms such as, but not limited to:
- Micrococcus luteus
- Escherichia coli (E. Coli)
- Staphylococcus aureus
- Bacillus subtilis
- Pseudomonas aeruginosa
- Salmonella enterica
- Candida albicans
The new instrument delivers precise results and swiftly identifying organisms with high accuracy — particularly crucial in light of the significant updates to EudraLex Annex 1 (Manufacture of Sterile Products) in August 2023.
Outline of Annex 1 Changes
Implementation of Contamination Control Strategy (CCS):
Operating in the pharmaceutical, cleanroom, or sterile manufacturing industries now mandates the implementation of a Contamination Control Strategy (CCS).
Vital Role of Viable Environmental Monitoring:
A crucial component of CCS involves viable environmental monitoring, aiming to prevent contamination in the final product.
Regular Review and Trend Analysis of Environmental Monitoring Data:
Environmental Monitoring data must be regularly reviewed and analysed. This includes the analysis of microorganisms recovered within a facility, making Microbial Identification essential for maintaining a contaminant-free environment.
Therefore, the updates to EudraLex Annex 1 in August 2023 have reinforced the necessity for precise microorganism identification in the pharma sector. Tentamus Pharma UK's MALDI-TOF addresses these changes by ensuring:
- Identification of microorganisms to the species level.
- Adherence to the revised Annex 1 mandates for enhanced quality control.
- Alignment with pharma industry standards, upholding the highest levels of product integrity in sterile product manufacturing, such as medical equipment.
This revolutionary advancement positions Tentamus Pharma UK as a true ambassador in delivering Good Manufacturing Practices, aiming to assist our partners and friends in meeting the regulatory requirements outlined in the updated Annex 1. We offer pharmaceutical companies an innovative solution for quality control processes.
