The importance of organic material which is used in medicine is rising constantly, both in all implants and in part in extracorporeal systems such as hemodialysis. The rapid development of new implants, respectively other solutions for tissue and organ replacement, has caused an increase in interest from the industry. Worldwide, there is a volume of 14 billion US dollars in the organic material sector, with a growth rate of 10-12%. Market leaders include, above all, Western Europe, the USA, and Japan.

Bio- and blood compatibility tests

Cytotoxicity: MTT-Test, Live/Dead-Test
Cytokine-induction: whole blood or PBMC-test with quantifizierung of cytokines (ELISA)
Complement activation: quantification of C3adesArg and C5adesArg with ELISA.
Blood coagulation activation: quantification of TAT, fibrinopeptide A
Metabolic change of blood cells due to contact with biomaterials:
- Erythrocytes (haemolysis)
- Thrombocytes (release of Serotonin)
- Granulocytes (release of Elastase)
- Monocyte (release of cytokines as TNF, IL-1Ra, IL-1b, IL-6)
Quantification of endotoxins (LAL-test)
Quantification of peptidoglycanes (SLP-test)

Clinical and biochemical analysis

Quantification of cytokines with ELISA
Quantification of uraemic toxins (BUN, Creatinine, b2-microglobuline)
Quantification of toxins in liver failure (bilirubin, phenole, tryptophan, fatty acids, bila acids)
Aminoacid analysis (HPLC, derivatisation with o-Phthtalaldehyd)

Mircoarray technology

Our Affymetrix 428 (confocal Microarray Laser Scanner) allows the analysis of gene expression (mRNA). It can also be used to scan commercially available antibody-arrays. The system works with Cy3/Cy5 marked probes. Analyses with the scanner are also offered as services.
