3D bio-impression of scaffolding for regenerative medicine

The principle of 3D bioprinting consists of selecting the most suitable biomaterials and cell types to prepare a Bioink that should be able to promote cell growth and differentiation and present appropriate mechanical properties of the target tissue.
This service possess a wide variety of 3D bioprinting techniques avaliable, such as extrusion, droplet, electrospining, electrowritting and stereolithography.

Customer benefits

One of the main characteristics of this additive manufacturing technique is its ability to bioprint the desired layers, with specific cell orientation , and desired morphology of the bioprinted 3D scaffold in order to ressemble, as much as possible, the tissue of interest. To achieve this goal, rheology, texturometry, printability and biological assays are carried out.

On the one hand, this technology can be employed to develop 3D scaffolds specific for the regeneration of particular tissues. On the other hand, this strategy offers a 3D environment that mimics the tissue/ organ of interest in order to test potential therapeutic tools, which goes in accordance with the implementation of the 3R principle (replace, reduce and refine).

Target customer

  • Preclinical use for in vitro and in vivo models.
  • Pharmaceutical industry (e.g. cosmetics)

U2-S07. Antibody purification

Antibody purification

Antibody purification involves the selective enrichment or specific isolation of antibodies from various sources, such as serum (for polyclonal antibodies), or cell culture supernatant (for monoclonal antibodies).

The main methods used for antibody purification are:

  • Physicochemical Fractionation: This method includes differential precipitation, size-exclusion, or ion exchange chromatography, based on size, charge, or other shared chemical characteristics It separates proteins that includes the immunoglobulins (antibodies) based on size, charge, or other shared chemical characteristics
  • Class-Specific Affinity: In this approach, specific antibody classes (e.g., IgG) are bound to solid phases using immobilized biological ligands (such as proteins A or G). This method purifies all antibodies of the target class without considering antigen specificity.
  • Antigen-Specific Affinity: Here, only antibodies in a sample that bind to a particular antigen are purified. Affinity chromatography is performed using a column packed with immobilized antigen (the same antigen used for immunization). Only antibodies that bind to the antigen are isolated. This method provides a higher yield of antigen-specific antibodies than Protein A/G affinity chromatography, though the total amount of recovered antibodies is lower.

Customer benefits

  • High Purity: Antibody purification ensures that the isolated antibodies are of high purity, minimizing contamination by other proteins.
  • Specificity: By using antigen-specific affinity purification, researchers obtain antibodies that specifically recognize their target antigen.
  • Consistent Results: Purified antibodies lead to more consistent and reliable experimental results.
  • Diagnostic and Therapeutic Applications: Purified antibodies are essential for diagnostic assays, therapeutic development, and research applications.
  • Quality: We operate under ISO 9001 quality standards, ensuring consistent, reliable antibody production.

Target customer

  • Research Institutions: Universities, research centers, and laboratories engaged in biomedical research.
  • Biotech Companies: Organizations involved in drug discovery, diagnostics, and therapeutic development.
  • Pharmaceutical Companies: Those working on antibody-based therapies or vaccines.
  • Healthcare Providers: Hospitals and clinics conducting specialized research.
  • Food & Environmental Quality Control Companies: Entities involved in:

U2-S06. In vitro antibody production

In vitro antibody production

We perform the production of monoclonal antibodies in vitro.
Hybridoma cells are first expanded in culture flask or high density culture devices (for larger amounts of antibody) to get the optimal cell density needed for the production.
The classical medium of production includes fetal calf serum (ultralow IgG, FCS) but our expertise allows us to provide a completely customized service according to your needs, without using FCS.
Supernatant containing the monoclonal antibodies is then periodically collected until the expected quantity of antibodies is obtained.

Depending on the nature of the sample, the expected antibody concentrations are for :­

  • Culture in flask: from 5 to 20 µg antibody/mL supernatant
  • ­ Culture in high density device : up to 1 mg antibody/mL supernatant

Customer benefits

  • Customization: The service can be tailored to meet the specific needs of each customer, allowing for personalized antibody production without using fetal calf serum (FCS).
  • Scalability: The service can accommodate both flask cultures and high-density devices, providing flexibility for different antibody quantities.
  • ISO 9001 Certification: We operate under ISO 9001:2015 quality standards, ensuring consistent and reliable antibody production.

Target customer

  • Research Institutions: Universities, research centers, and laboratories engaged in biomedical research.
  • Biotech Companies: Organizations involved in drug discovery, diagnostics, and therapeutic development.
  • Pharmaceutical Companies: Those working on antibody-based therapies or vaccines.
  • Healthcare Providers: Hospitals and clinics conducting specialized research.

U2-S05. Monoclonal Antibody development

Monoclonal Antibody development

To develop customized monoclonal antibodies, we adapt our protocols at each critical stage of antibody production. This includes designing the antigen, immunization protocol, and screening design of hybridoma cell supernatants. The initial step involves immunizing mice or rats with a specific antigen. We can develop monoclonal antibodies against various antigen types, such as proteins, peptides, small molecules, or cells. The immunization process typically spans 10-12 weeks. The animal with the most robust immune response undergoes a final immunization to stimulate antibody-producing cells. Spleen cells are isolated and fused with immortal myeloma cell lines to create hybridoma cells. The chosen hybridoma clones are then subcloned to ensure cell stability and maintain their monoclonal characteristics. Finally, the isolated cells are expanded and cryopreserved.

Customer benefits

  • Versatility: Monoclonal antibodies can be used in diagnostics, therapeutics, and research.
  • Customization: Protocols can be adapted to meet specific needs
  • Quality Assurance: Our processes adhere to the ISO 9001 quality requirements.

Target customer

  • Organizations involved in research and development, pharmaceutical companies, academic institutions, and diagnostic laboratories benefit from monoclonal antibody development.
  • Researchers studying diseases, drug targets, and immune responses rely on mAbs for their work.
