Regulatory Changes
USA accept animal-free procedure of endotoxin testing

What has been permitted in the European pharmacopeia since 2018 is now also permitted in the USA – The recombinant Factor C (rFC) test has finally been accepted by the US pharmacopeia and will become official in May 2025. This test copies the LAL test and uses recombinant Factor C. The protein is produced recombinantly by genetically modified microorganisms and thus replaces the naturally occurring Factor C in the blood of horseshoe crabs. More precise results can be achieved and no animals have to suffer and die for it.


But be aware! The rFC test as well as the LAL-test only detect endotoxin pyrogens. Non-endotoxin pyrogens can only be detected by a complete pyrogen test- such as our NAT-MAT®

Product Highlights
Coming soon: Complete pyrogen testing by combining the power of digital PCR with MAT

In the pharmaceutical industry, pyrogen detection is mandatory to avoid life-threatening fever reactions that can be induced by both microbial and non-microbial substances.

Minerva Biolabs has developed a next generation MAT system that measures the gene expression of IL-1β and TNFα using digital PCR - the NAT-MAT®. The NAT-MAT® enables complete pyrogen testing and detects endotoxin as well as non-endotoxin pyrogens. The test can be conducted as in-process control and as final release testing of medicinal products according to Ph. Eur. 2.6.30.

Beta Testers Wanted!

Minerva Biolabs is looking for suitable testers for NAT-MAT®. Send a mail to miquant@minerva-biolabs.com to get more information.

Here's to clean cultures and reliable results!
