背景

Trefoil peptides are protease resistant molecules secreted throughout the gut that play a role in mucosal healing. Trefoil peptides contain three intrachain disulfide bonds, forming the trefoil motif, or P-domain and clustered in human chromosome 21q22.3. Trefoil Factor 3 (TFF3) is one of three trefoil peptides secreted by epithelial cells that line mucus membranes in the large and small intestines and lower respiratory tract. TFF3 is mainly active as a disulfide-linked homodimer and may have a role in promoting cell migration in healing processes. It is involved in the maintenance and repair of the intestinal mucosa.

石蜡包埋组织的免疫组织化学方案

1. 脱蜡水化

石蜡切片置于新鲜二甲苯中浸泡脱蜡3次，每次15 min；依次置于不同浓度（100%、95%、90%、80%、70%）乙醇浸泡各5 min，再置于蒸馏水洗涤5 min，重复3次。

2. 抗原修复

沸水浴修复：将100×抗原修复缓冲液（试剂2）用蒸馏水稀释成1×抗原修复缓冲液，放入修复盒中并提前加热至95-100℃（注意盖好以防液体蒸发），然后将切片放入修复盒中，在沸水浴环境中保持外沸状态15 min，室温自然冷却；用PBS缓冲液（试剂1，将干粉溶解在2L蒸馏水中）清洗5 min，重复3次。

3. 阻断内源性过氧化物酶

用吸水纸吸去玻片上多余的液体，用免疫组化笔在组织周围画圈，加入2-4滴内源性过氧化物酶阻断剂（试剂3），室温下置于湿盒中孵育15 min，用PBS洗涤5 min，重复3次。

4. 血清封闭

用吸水纸吸去玻片上多余的液体，加入2-4滴封闭工作液（试剂4），置于湿盒内37℃封闭20 min，以减少非特异性染色。

5. 一抗孵育
