注意事项：

This product as supplied is intended for research use only, not for use in human, therapeutic or diagnostic applications.

操作步骤如下：

1. 样本准备

‌血清/血浆‌：室温凝固后离心（2000-3000转/分，20分钟），收集上清。若出现沉淀需再次离心。

‌细胞培养上清‌：离心后收集上清；检测细胞内成分时需用PBS稀释并反复冻融。

‌组织标本‌：液氮冷冻后匀浆，离心取上清。

2. 免疫印迹（WB）

‌电泳‌：SDS-PAGE分离蛋白。

‌转移‌：半干法转膜至NC膜，恒流1mA/cm²转移1.5小时。

‌免疫反应‌：

一抗4℃孵育12小时。

二抗室温孵育2小时，显色后终止反应。

3. 免疫组化（IHC）

‌组织处理‌：石蜡切片需胰酶消化（37℃ 15-60分钟）。

‌抗体孵育‌：一抗室温孵育1小时，二抗37℃孵育30分钟。

‌显色‌：DAB显色5-10分钟，苏木精复染。

4. 免疫细胞化学（ICC/IF）

‌细胞固定‌：4%多聚甲醛固定10-15分钟。

‌抗体孵育‌：一抗4℃过夜，二抗室温避光孵育。

主要特性：

‌特异性：抗体能够识别并结合特定抗原分子上的特定区域（抗原决定簇），这种结合具有高度选择性，确保免疫反应的精准性。

多样性：B细胞可产生数以百万计的不同抗体，每种抗体针对不同的抗原。这种多样性使机体能够应对各种病原体及其毒素。

亲和力与亲合力：

亲和力：指抗体分子上一个抗原结合位点与抗原表位之间的结合强度，由抗体超变区与抗原表位的互补程度决定。

亲合力：指一个抗体分子与抗原分子表面多个抗原决定簇之间的总结合强度，与抗体的价数相关（如IgG为双价，IgM为5-10价）。

公司正在出售的产品：

短期保存‌：4°C 可保存数月，避免反复冻融。
