● Introduction：

ABAis involved in several physiological mechanisms including seed dormancy, leaf abscission, stomatal movement, and plant stress responses. Through complex interactions with several intracellular signaling systems, it can regulate the expression of hundreds of plant genes. Natural ABA [(+)-ABA] is dextrorotatory（右旋）. The synthetic ABA [(±)-ABA] is a mixture of (+)-ABA and (-)-ABA.

● Stability:

The ABA power should be stored at-20℃and protected from light. TheABAsolutions are stable for1 year at least when stored at-20 °Cand protected from light.

●  ABA母液配制方法：

1 mg/ml ABA母液：配制量 10 ml

取10 mg (±)ABA粉末置于合适容器中，加入2 ml 无水乙醇至粉末彻底溶解，缓慢加入双蒸水，边加边混匀，最后用水定容至10 ml。0.22μm水系滤膜抽滤除菌后，适量分装-20℃避光保存。
