生物活性

Lei-Dab7 is a potent and selective SK2 (KCa2.2) channels blocker with a Kd of 3.8 nM. Lei-Dab7 shows low or no activity on KCa1, KCa3, Kv and Kir2.1 channels[1][2].

体内研究
(In Vivo)

Intracerebroventricular (9-5 ng) injections of Lei-Dab7 decreases locomotor activity, food intake and body weight in rats deprived of food. A dose of 3 ng Lei-Dab7 has no effect on these types of behavior[3].

MCE has not independently confirmed the accuracy of these methods. They are for reference only.

产品简介

DAB试剂货号:D006 3,3′-Diaminobenzidine, tetrahydrochloride CAS号:7411-49-6

DAB是在免疫组化中最常用的氧化型过氧化物酶显色底物之一。在过氧化氢和过氧化酶存在时,DAB被氧化成棕色的显色底物。这种棕色的显色底物是苯胺黑类化合物,可以牢固的沉积在细胞膜或组织上的过氧化物酶的周围。市面上销售的DAB往往由于生产和保存期间的氧化问题呈褐色。而同仁化学研究所的提供的高纯度DAB的性状呈白色或略带红色的灰色粉末,可以得到灵敏度更高的染色效果。

染色溶液的制备

1. 用1 ml PBS溶解9 mg DAB制备成100 x DAB solution。

2. 用1 ml PBS混合5 μl 的30%过氧化氢酶溶液制备成200 x H2O2 solution。

3. 向1 ml PBS中加入10 μl 的100 x DAB solution和5 μl的 200 x 的H2O2 solution制成Staining soluiton1)

4. 将Staining solution加入到染色容器中并将样品在室温下培养1 h2)

5. 用PBS清洗样品数次使染色反应停止。

1) Staining solution不稳定,请现配现用。

2) 为了获得更好的染色效果,可以在加入Staining solution之前预先用0.09 mg DAB/PBS溶液培养样品10 min。
