产品描述(Description)：
| General description | 脱落酸(Abscisic Acid, ABA)，也称为脱落素II (Abscisin II)或休眠素(Dormin)，是一种天然生成的植物激素和生长抑制剂，参与诱导植物多种生理反应，包括胚胎成熟、种子休眠(Seed dormancy)、叶子脱落(Leaf abscission)、气孔关闭(Stomatal closing)、影响开花和性分化；以及诱导植物对干旱、盐度、寒冷、病原体攻击和紫外线辐射等胁迫做出反应。 |
| Application | 本品是纯化的右旋脱落酸((+)-Abscisic Acid，或S-Abscisic Acid)，是天然存在且有活性的异构体。适用于植物组织培养，有效工作浓度为0.1-10mg/L。 |

-20ºC保存，两年有效。
注意事项：脱落酸有顺式和反式两种构型，以及右旋(+)和左旋(-)两种旋光体。天然存在的脱落酸是右旋的。化学合成的脱落酸是左旋和右旋混合体(±)。两种异构体都有生物活性，但研究发现左旋不能促进气孔关闭。另外较低浓度下(1-10µM)，(+)-脱落酸活性明显高于(-)-脱落酸。
本产品对光敏感，注意避光保存。
本产品未经无菌处理，若用于植物组织培养或细胞实验，请提前做好预处理。
本产品配制成无菌溶液后，请分装保存，避免反复冻融造成的产品失效。
本产品仅限于专业人员的科学研究用，不得用于临床诊断或治疗，不得用于食品或药品，不得存放于普通住宅内。
为了您的安全和健康，请穿实验服并戴一次性手套操作。
