Peptide Sterility Testing Service

MtoZ Biolabs provides a professional Peptide Sterility Testing Service to verify the absence of microbial contamination in peptide-based therapeutics, conjugates, and formulation products.


During peptide synthesis and formulation, microbial contamination can occur through exposure to aqueous systems or handling environments, potentially compromising product stability, biological activity, and safety. Sterility testing is therefore essential to confirm that peptide materials are free of viable microorganisms prior to use in research or development applications.


MtoZ Biolabs employs validated microbiological detection methods under controlled cleanroom conditions to ensure reliable, contamination-free results. Our Peptide Sterility Testing Service supports peptide production quality assurance and provides clients with data suitable for both research documentation and product release evaluation.

 

Peptide Sterility Testing Service at MtoZ Biolabs

MtoZ Biolabs applies two validated testing approaches for detecting microbial contamination in peptide samples, selected according to sample type and characteristics.

1. Direct Inoculation Method

Applied to soluble peptides or limited-volume samples. The material is directly inoculated into culture media under aerobic and anaerobic conditions to detect potential microbial growth.

 

2. Membrane Filtration Method

Used for peptide solutions or formulations with adequate volume. Samples are filtered through sterile membranes, and filters are transferred into growth media to evaluate microbial presence.

 

Both methods are performed in aseptic cleanroom environments using validated culture systems to detect a wide spectrum of aerobic and anaerobic bacteria, fungi, and yeast.
