[Evaluation of usability of an anticancer drug after changing it to liquid formulation].

Although the advantages of a liquid formulation over a lyophilized one have been mentioned, few studies have quantified the differences between the two. For the purpose of clarifying the advantages of a liquid formulation, we carried out a comparison of ELPLAT I. V.

Novel endotoxin assay by laser light-scattering particle-counting method.

Exposure of Limulus amoebocyte lysate to endotoxin under stirring produced light-reflective particles that appeared to be coagulin polymers. A laser light-scattering particle counter, the PA-200, detected these particles sensitively. The PA-200 detected endotoxin at a concentration as low as 0.
