ex vivo and in vitro testing. 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, to measure parameters such as cytotoxicity (USP 87), hemocompatibility, irritation, corrosion, and proliferation viability. 

Our 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.
