For pollen, using a fast, easy-to-use, and highly accurate tool to determine pollen quality aides in the study of abiotic factors such as temperature, humidity, and radiation to determine their negative impact on pollen viability, quantity, and quality.
Cell viability assays use a variety of markers as indicators of metabolically active (living) cells. Examples of markers commonly used include measuring ATP levels, measuring the ability to reduce a substrate, and detecting enzymatic/protease activities unique to living cells. See more When using our plate-based assays, choosing the right type of plate is dependent on your research needs.
