Used in plant biology research to detect and quantify osmotin proteins, which play a key role in plant defense mechanisms against environmental stresses such as drought, salinity, and pathogen attack. The ELISA kit allows researchers to measure osmotin levels in plant tissue extracts, helping in the study of stress response pathways and the development of stress-resistant crop varieties. It is widely applied in agricultural research, biotechnology, and plant physiology studies where accurate measurement of osmotin accumulation is needed to evaluate plant health and genetic modifications.
