| Background | CYP3A4 (cytochrome P450, subfamily 3A, polypeptide 4) belongs to the cytochrome P450 superfamily of monooxygenases that catalyze reactions involved in both drug metabolism and the synthesis of cholesterol, steroids, and other lipid components. CYP3A4 is predominantly found in liver microsomes, but has also been detected in prostate, small and large intestine, bile duct, nasal mucosa, kidney and adrenal cortex. It is an extremely important enzyme for drug metabolism; CYP3A4 catalyzes phase I oxidation reactions in an estimated 60% of all clinically used drugs, promoting in most cases their clearance by excretion. CYP3A4 levels are induced by glucocorticoids and various xenobiotics, including drugs, pesticides and carcinogens. Human CYP3A4 is a 50 kDa single-pass membrane protein, 503 amino acids in length. |
包装清单：
| 产品编号 | 产品名称 | 包装 |
| AF6654 | CYP3A4 Rabbit Polyclonal Antibody | 50μl |
| AZ050 | Western一抗稀释液 | 50ml |
| — | 说明书 | 1份 |
保存条件：
CYP3A4 Rabbit Polyclonal Antibody -20ºC保存，Western一抗稀释液-20ºC或4ºC保存，一年有效。Western一抗稀释液优先推荐4ºC保存，长期不使用可以考虑-20ºC保存，但冻融可能会导致出现轻微的浑浊和少量不溶物。
注意事项：
如果本抗体用于Western blot (WB)、免疫荧光(IF)、免疫细胞化学(ICC)等实验，请注意回收使用过的稀释抗体。回收的抗体通常至少可以重复使用5-10次。稀释后的抗体，包括已经使用过的稀释抗体，请4℃保存。
回收后重复使用的抗体，使用方法同新鲜稀释的抗体。如果在重复使用过程中发现抗体出现轻微混浊现象，可以10,000g离心1-3分钟，取上清用于后续检测。如果回收的抗体出现明显的絮状物或长霉长菌等情况，则可以考虑废弃该抗体。
提供的Western一抗稀释液也可以用于免疫荧光(IF)、免疫组化(IHC)、免疫细胞化学(ICC)等适当用途。如果希望获得最佳的检测效果，请考虑使用上述检测专用的一抗稀释液。
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。
使用说明：
请根据抗体的实际用途选择相应的使用方法。
1. Western检测：
a. 按照推荐的稀释比例用碧云天提供的Western一抗稀释液稀释抗体。
b. 把经过封闭的蛋白膜与稀释好的一抗4℃缓慢摇动过夜或室温缓慢摇动2小时，确保稀释的抗体至少能在摇动的瞬间覆盖蛋白膜。
c. 回收稀释的一抗，4℃保存以备下次继续使用。
d. 按照Western的实验步骤进行后续的洗涤、二抗孵育、洗涤和检测等操作。具体操作可以参考如下网页：
http://www.beyotime.com/western.htm
2. 免疫染色：
可以使用碧云天生产的免疫染色一抗稀释液(P0103)稀释抗体，使用后注意回收稀释好的一抗，具体操作可以参考如下网页：http://www.beyotime.com/support/immunol-staining.htm
3. 其它实验操作请自行参考适当的protocol进行。
