Used in environmental and plant physiology research to quantify demagnesium chlorophyll a, a degradation product of chlorophyll, in plant and algal samples. Helps assess plant stress, senescence, and photosynthetic health under adverse conditions such as light stress, nutrient deficiency, or pathogen attack. The ELISA format allows for high sensitivity and specificity, enabling researchers to detect low levels of demagnesium chlorophyll a in complex biological matrices. Widely applied in studies related to chlorophyll catabolism, ecosystem monitoring, and post-harvest quality assessment of plant materials.
