11. Bioassay -guided fractionation is a common method to find biologically active compounds.12. Mutatox is another similar bioassay approach that uses bioluminescent bacteria to determine genotoxicity. 13. Bioassays and immunoassays are utilized for toxicity evaluations of chemical effects on various organisms.14. BioImage specializes in developing and selling proprietary bioassays to biopharmaceutical companies and research institutions. 15. There are many different bioassays available for testing. 16. A bioassay " Culex pipiens " was followed to test the activities. 17. Sediment toxicity is evaluated based on bioassay analysis. 18. It is a relatively weak estrogen in bioassays . 19. Most commonly, the presence of a phycotoxin is verified by bioassay -guided fractionation. 20. This includes air, soil, vegetation, water, bioassays , and swipe samples.
