Artemia salina Toxicity Assay: Standardization in a 24‐Well Microplate
Environmental Toxicology, EarlyView.ABSTRACT Bioassays with Artemia sp. are widely used in aquatic, environmental, and human toxicology as an initial tool to investigate the toxicity of plant extracts, isolated compounds, drugs, and products of natural or synthetic origin. These assays allow for the estimation of the median lethal concentration (LC50) and guide subsequent studies in ...
