tations of GD [12] . TSHR bioassays show outstanding features. The biological activity of specific immunoglobulins is directly assessed on a fully functional TSHR holoreceptor expressed on intact live cells, a platform that is easily adaptable and tailored to detect Ab of specific function. The TSHR protein structure can be bioengineered and stably expressed in cell lines with protocols optimiz...

Geographical variation in chemical tolerance within a species can significantly influence results of whole animal bioassays, yet a literature survey showed that the majority of articles using bioassays did not provide detail on the original field collection site of their test specimens confounding the ability for accurate replication and comparison of results. Biological variation as a result o...

The linear correlation between the EC50 values of 50 substances obtained in luminescence bioassays using Vibrio fischeri and Vibrio harveyi and in a fluorogenic bioassay using Escherichia coli was investigated. As a result, a significant correlation was found between the said values in all three toxicity tests. The bioassay using V. harveyi had a sensitivity similar to that of the fluorogenic b...

Lymphomas were reported to be induced in rats in bioassays of aspartame, methyl-tertiary-butyl ether (MTBE), and other chemicals conducted by a nonprofit cancer research organization. European regulatory authorities concluded that lymphomas in the aspartame study were caused by Mycoplasma pulmonis and suggested that this also was the case for the MTBE bioassay. To assess the role of M. pulmonis...

Substantial tracts of land in the southwestern and western U.S. are undergoing or will require ERA. Toxicity bioassays employed in baseline ERAs are, for the most part. representative of mesic systems, and highly standardized test species (e.g., lettuce, earthworm) are generally not relevant to arid system toxicity testing. Conversely, relevant test species are often poorly characterized with r...
