Lyophilisation
What is lyophilisation?
Lyophilisation is the process of freeze-drying your assay to prolong its life without the need for cold chain transportation and storage.
It is one of the best drying methods that is used in the for the preservation of many different heat-sensitive materials including: microbes, proteins, pharmaceuticals, plasma, and tissues.
The lyophilisation process involves removing water from a product to the point where it is no longer biologically or chemically active and offers a method of stabilising assays that contain heat sensitive components.
We are a leading contract assay developer and manufacturer with a wealth of lyophilisation experience. We analyse your formulation to determine its characteristics and critical temperatures in order to design an optimal, efficient and cost-effective lyophilisation process.
Our lyophilisation services
Lyophilisation Contract Services
We offer our lyophilisation expertise and experience to assay developers as an ISO13485 contract development and manufacturing service.
This proprietary service can be applied to your molecular reagents resulting in:
We also offer Freeze Drying Microscopy to analyse your assay mix to facilitate the optimisation of freeze drying protocols.
PCR reagents, Isothermal reactions, Proteins, Enzymes, Immunoassays can be stabilised into instantly soluble freeze-dried cakes or beads.
The result: simple, stable and long lasting assays for easy transport and storage at room temperature.
Freeze-dried kits are ideal for multiple molecular diagnostic applications including:
Our state of the art dedicated laboratories and production facilities are ISO 13485 certified for the production of IVD kits. Together with our R&D facilities we can offer a complete assay design and development and validation and manufacturing service.
Lyophilisation Analytical Services
In order to deliver the highest possible freeze dried performance of your mix, Biofortuna offers freeze-dried microscope analysis. The freeze-dried microscope analysis allows us to do the following product optimisation:
This can be used with our Molecular Assay Design and Development Service to optimize your assays and reagents.
Pictures 1 & 2 show typical images from our FDM system.
Picture 1 – A glycerol free mix is frozen (e.g -40°C). The vacuum is then applied to initiate drying. A drying (sublimation) front moves across the sample as water is removed. The sample temperature is then slowly increased.
Picture 2 – Temperature is reached when the sample cannot hold its structure without water present. As water is removed the sample ‘collapses’. The example above shows a collapse onset temperature of -27°C and a complete collapse at -25°C. The primary drying should be performed 2-8°C below the onset of collapse.
