Freeze Drying – Lyophilisation
NCIMB offers a convenient freeze drying service that can help you to maintain and preserve your own stock cultures. Freeze drying, or lyophilisation, is one of the most reliable methods for preparing bacterial cultures for long term storage, and at NCIMB we have decades of experience of using this method to preserve our own reference collection.
Why freeze dry your cultures?
Many laboratories maintain their own collection of stock cultures for production, research or QC uses, but repeated subculturing can leave these cultures vulnerable to contamination and genetic drift. It is good practice to preserve strains that you work with for long term storage. This can help to reduce the number of passages and the subsequent risk of strain drift.
We can freeze dry your cultures and return them to you ready for long term storage.
Why use NCIMB?
Do you really know the strains you are working with? Use our whole genome microbial sequencing services to get to know the strains you work with inside out. Sequences can be used to periodically check for genetic drift in working stocks. We can also screen sequences for properties such as antimicrobial resistance or virulence factors.
We also offer a storage service to provide an offsite back-up to protect again equipment failure or other disasters.
What you can send for freeze-drying
Our freeze drying service is for small batches, to help laboratories store and maintain their own stocks.
We can accept strains ACDP category 1 and 2 strains for freeze drying. NCIMB does not accept active cultures of dangerous human pathogens or organisms isolated from clinical or diseased plant materials for identification. We cannot accept strains known to be above ACDP category 2 and ACGM class 1.
