Why Lyophilization?

Lyophilization Technologies is a dehydration process that takes place after a product has been frozen. Lyophilization is popular in life sciences because lyophilized reagents and assays have many benefits including ease of use and reduced total cost. Lyophilized reagents ship at ambient temperature, reduce storage and shipping costs. Lyophilized products also have a longer shelf life, leading to less waste. 

benefits of lyophilizED ASSAYS & REAGENTS

Lyophilized products use less warehouse space, lower electrical and equipment costs, and reduc environmental impact. Ambient shipping is more flexible and less risky in todays complex shipping environment.

Shipments, even with critical enzymes, can be bumped off flights due to weight and dry ice. Lyophilization eliminates risk of temperature variations. No more dry ice delays. Prevent excess and obsolete inventory.

Lyophilized reagents, enzymes, beads and antibodies have been shown to be stable for years in lyophilized format. Stab-tests show antibodies >20 years old that perform like the day they were lyophilized.

Lyophilization eliminates difficult small-volume pipetting steps. Reduce user errors with simpler protocols.

Cold chain shipping adds 40x shipping material weight for domestic and 80x weight for international, compared with ambient shipping with lyophilized products! Lyophilization eliminates styrofoam coolers and dry ice. Your product ships in recyclable containers, and boosts environmental goals and regulatory compliance.

Argonaut is the exclusive producer of LyoDose beads, a proprietary spherical lyophilized bead format that contains a specified volume of reagent.

CDMOs play a crucial role in ensuring the quality of the products they manufacture and maintaining compliance with applicable regulations.

To achieve this, reputable CDMOs like Argonaut implement a comprehensive approach that includes the following elements:

Quality Management System (QMS): A robust QMS is the backbone of a CDMO’s quality and compliance efforts. The QMS includes policies, procedures, and guidelines that govern every aspect of the life science and IVD manufacturing process, from raw materials sourcing to finished product release.

Compliance with Good Manufacturing Practices (GMP): CDMOs adhere to GMP guidelines and other relevant industry standards to ensure that products are consistently manufactured according to quality requirements. GMP guidelines cover various aspects of the production process, including personnel qualifications, equipment maintenance, and record-keeping.

Regulatory expertise: CDMOs employ experienced regulatory affairs professionals who are knowledgeable about local and international regulations, industry standards, and best practices. These professionals help ensure that the CDMO stays up-to-date with the latest regulatory changes and maintains compliance throughout the life science or IVD manufacturing process.

Regular audits and inspections: CDMOs undergo regular audits and inspections by both their clients and regulatory authorities to verify that they maintain compliance with applicable regulations and quality standards. These inspections help identify potential issues and ensure that corrective actions are taken promptly.

Employee training: CDMOs invest in continuous training and education for their employees to ensure that they have the necessary skills and knowledge to maintain quality and compliance. This includes training on relevant regulations, industry standards, and best practices.

Quality control and assurance: CDMOs implement rigorous quality control (QC) and quality assurance (QA) processes throughout the life science and IVD manufacturing process. QC involves testing and monitoring of raw materials, intermediate products, and finished products to ensure that they meet established specifications. QA focuses on the overall quality management system and helps identify and address potential issues before they impact product quality.

Documentation: CDMOs maintain thorough and accurate documentation of their life science and IVD manufacturing processes, quality control results, and compliance efforts. Proper documentation is essential for demonstrating compliance with regulations and facilitating audits and inspections.

Continuous improvement: CDMOs are committed to continuous improvement in their quality and compliance efforts. They regularly review their processes, systems, and performance to identify areas for improvement and implement necessary changes.

By implementing these measures, reputable CDMOs like Argonaut can ensure that they consistently deliver high-quality products while maintaining compliance with applicable regulations. Partnering with a CDMO that prioritizes quality and regulatory compliance can provide peace of mind and help minimize potential risks associated with life science or IVD manufacturing.

The cost of outsourcing your life science or IVD manufacturing to a CDMO can vary significantly depending on several factors, such as the complexity of your product, the scale of production, the CDMO’s expertise and capabilities, and the scope of services required.

To better understand what to expect in terms of cost, consider the following factors:

Manufacturing complexity: Complex products, such as biologics, may require specialized equipment, advanced life science or IVD manufacturing techniques, or highly skilled personnel, leading to higher costs compared to simpler products.

Volume and scale: The cost per unit typically decreases as the volume of production increases, due to economies of scale. However, if your production requirements exceed the CDMO’s existing capacity, additional investments in equipment or facility expansion may be necessary, impacting the overall cost.

Scope of services: The cost of outsourcing will depend on the range of services you require from the CDMO, such as supply chain management, technical transfer, engineering development, regulatory support, or quality assurance. A more comprehensive scope of services will likely result in higher costs.

Development and tech transfer costs: The process of transferring your product’s life science or IVD manufacturing technology and know-how to the CDMO may require additional resources and time, impacting the overall cost of outsourcing.

Regulatory compliance and quality assurance: Ensuring that your product meets regulatory requirements and quality standards can be resource intensive. This includes the cost of implementing and maintaining a robust quality management system, as well as conducting regular audits and inspections.

Geographic location: The location of the CDMO’s facilities can impact the cost of outsourcing due to differences in labor costs, taxes, regulations, and logistics.

Contract terms and negotiation: The final cost will also depend on the specific terms and conditions negotiated in your contract with the CDMO. This can include factors such as payment terms, intellectual property rights, liability, and performance guarantees.

To get an accurate estimate of the cost of outsourcing your life science or IVD manufacturing to a CDMO, it is essential to clearly define your requirements and engage in a thorough evaluation and negotiation process. A reputable CDMO like Argonaut can help you navigate this process and provide a transparent, competitive, and fair pricing structure that takes into account your specific needs and expectations.

A: Lyophilization requires careful optimization of parameters. Our lyophilization feasibility program determines the best manufacturing process for your product, prior to full-scale production. The feasibility study produces small batches of lyophilized product with three different excipients (inert components that stabilize products during the lyophilization process), which are then tested. This facilitates selection of the best excipient for optimal lyophilization. You can read more about feasibility studies in “Your Guide to Outsourcing Reagent & Assay Lyophilization“.
A: Lyophilization is also known as freeze drying. It is a dehydration process that takes place after a product has been frozen. Lyophilization is gaining popularity in the life sciences for reagents and assays due to its numerous benefits, including extended shelf-life and ease-of-use. Read more in “Lyophilization Process- The Argument for Specialization“.
A: Argonaut offers a wide range of reagent lyophilization services options. Our most popular format is LyoDose™ beads, although in situ, vials, and swabs are also common. Drug products are not able to be lyophilized at this time.
