Cell Culture and Testing

Perfectus Biomed specialise in cell culture to support the biological evaluation of your product.

We use in vitro wound models and cell models to aid biocompatibility assessments using ISO 10993 guidance. We measure parameters such as cytotoxicity (USP 87), hemocompatibility, irritation, corrosion and proliferation viability. Testing to GLP is available.

Perfectus Biomed work closely with our clients, from study design to production of the scientific report.

We typically offer cell services to support our clients for one of three reasons:

1. Research and Development: product development, screening and pre-clinical data.

2. Biocompatibility and Sfety/regulatory Requirements: legal requirements and label claims.

3. Marketing: evidence to support the product on the market by highlighting competitive advantages, differentiations and USPs.

Biocompatibility and Safety Testing

  • In vitro cytotoxicity: BS EN ISO 10993-5
  • In vitro skin irritation using 3D reconstructed human epidermis: OECD 439
  • In vitro skin corrosion using 3D reconstructed human epidermis: OECD TG431

Regulatory and Label Claims

  • In vitro virucidal activity: BS EN 14476
  • Macrophage activation assay (assessment for inhibition)
  • Colonised skin model: in-house method

Marketing and Research & Development

  • Scratch wound model: in-house method
  • Conference abstracts and presentations

We help companies to accelerate their pipeline, expand product claims and highlight competitive advantages.
