Used in plant physiology research to quantify isoprenyl adenine nucleoside (iPA), a type of cytokinin hormone, in plant tissues. Helps scientists study plant growth regulation, cell division, leaf senescence, and responses to environmental stresses. Commonly applied in agricultural research, breeding programs, and physiological studies where precise measurement of cytokinin levels is required. The ELISA format allows for high sensitivity and specificity, enabling researchers to analyze hormone dynamics in various plant species under controlled or experimental conditions.
