摘要:
This application discloses a multivalent opsonophagocytosis assay that does not rely on counting of bacterial colonies to determine bacteria viability following opsonophagocytosis. Instead, the method uses a metabolic colorimetric indicator to determine if viable bacteria are present. Also disclosed are arrays that can be used to determine the viability of bacteria following opsonophagocytosis.

摘要:
Protein markers of toxicity and efficacy for antilipemic drugs are determined. Methods and reagents are disclosed for determining whether a patient receiving an antilipemic drug, especially a statin or HMGCoA reductase inhibiting drug, is experiencing drug efficacy and/or toxicity. Individual susceptibility is also determined prior to treatment. Also, drug discovery of similar acting candidates and their likelihood of being toxic or effective is determined by analysis of all proteins in a sample simultaneously by 2-dimensional gel electrophoresis.
