ISO 10993, IN VITRO AND EX VIVO STUDIES

GLP COMPLIANT

CELL CULTURE TESTING

 

Ex vivo and in vitro testing to ISO 10993 guidance and also GLP complaint. Perfectus Biomed specialise in cell culture and biocompatibility testing to support the biological evaluation of your product.

The body responds to foreign bodies, even relatively inert biomaterials, with inflammation, an integral part of the healing process. However, sustained inflammation may indicate chronic infection or foreign body response, resulting in fibrosis, encapsulation, and consequent failure of implantable devices. It is critically important to consider the host inflammatory response when developing products such as antimicrobial formulations, cosmetics and skincare products, implantable devices, and wound dressings.

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

Our US laboratory offers a range of ex vivo studies including human tissue models to test product antimicrobial efficacy, biomarker assessments and host cell toxicity on wounded and unwounded skin.

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 Safety/Regulatory Requirements: legal requirements and label claims.
  3. Marketing: evidence to support the product on the market by highlighting competitive advantages, differentiations and USPs.
