A bioassay is an analytical method to determine the potency or effect of a substance by its effect on living animals or plants (in vivo), or on living cells or tissues (in vitro). [1] [2] A bioassay can be either quantal or quantitative, direct or indirect. [3] If the measured response is binary, the assay is quantal; if not, it is quantitative ...

A bioassay is the use of a plant, or plant organ or tissue, to measure its response to a specific plant growth regulator. Because there are many naturally occurring hormones and literally hundreds of their synthetic analogues and because these PGRs affect a wide spectrum of phenomena in plant growth and development, the number of bioassays is ...

Quantitative estimation of a known or suspected biologically active substance (such as a hormone or drug) by measuring its effect on a living organism in standard conditions is known as bioassay.

Note: Depending on the virus, the bioassay plants used and symptoms produced, some combinations of host response may be diagnostic for identification of a particular virus 3/11/2016

Aplant bioassay is a simple, inexpensive, accurate and direct method of determining if it is safe to grow crops on farmland previously treated with known herbicides or on cropland with an unknown history of herbicide use. A bioassay can detect if herbicide or chemical residues are present in the soil at concentrations high enough to

2017年9月6日 · Plant bioassays are usually based on the detection of chromosomal abnormalities in mitosis, sister chromatid exchanges (SCEs), and, recently, on the DNA damage analysis. Point mutations such as chlorophyll mutations in leaves, waxy mutations, or embryo mutations of Arabidopsis are the other detection methods [17].

2023年12月14日 · Bioassays are an essential part in studying the biological activity of identified and putative plant peptides. Root growth assays and cultivated plant cell cultures are widely used to evaluate the regulatory potential of plant peptides during growth, differentiation, and …

A biological assay, or bioassay, is an analytical method used to measure the functional activity of a molecule on living organisms, tissue, or live cells. From: Best Practice & Research Clinical Endocrinology & Metabolism , 2023

2014年1月1日 · This chapter describes and provides comments on the following basic features of laboratory bioassays: (a) biotic and physicochemical factors, (b) test materials, (c) measurements, hypotheses, experimental designs, and data analyses, and (d) basic information that should be provided by researchers for all bioassays.

What’s a bioassay and how does it work? A bioassay is a method that uses plants, animals, or other living things to measure the harmful effects of environmental pollution. This method works by exposing living things to different environmental samples, like soil or water, that vary in how polluted they are.
