Full Description

1.1''This test method provides a methodology to assess the cytotoxicity of suspensions of nanoparticulate materials in porcine proximal tubule cells (LLC-PK1) and human hepatocarcinoma cells (Hep G2), which represent potential target organs following systemic administration.

1.2''This test method is part of an in vitro preclinical characterization cascade.

1.3''This test method consists of a protocol utilizing two methods for estimation of cytotoxicity, 3-(4,5-dimethylthiazolyl-2)-2,5-diphenyltetrazolium bromide (MTT) reduction and lactate dehydrogenase (LDH) release.

1.4''The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
