Osteoprotegerin Protein, Human, Recombinant (aa 22-401, His)

产品编号 TMPJ-01466

TNFRSF11B is a secreted protein, containing 2 death domains and 4 TNFR-Cys repeats. TNFRSF11B is a decoy receptor for the receptor activator of nuclear factor kappa B ligand (RANKL). By binding RANKL, TNFRSF11B inhibits nuclear kappa B (NF-κB) which is a central and rapid acting transcription factor for immune-related genes, and a key regulator of inflammation, innate immunity, and cell survival and differentiation. TNFRSF11B levels are influenced by voltage-dependent calcium channelsCav1.2. TNFRSF11B can reduce the production of osteoclasts by inhibiting the differentiation of osteoclast precursors (osteoclasts are related to monocytes/macrophages and are derived from granulocyte/macrophage-forming colony units (CFU-GM)) into osteoclasts and also regulates the resorption of osteoclasts in vitroand in vivo. TNFRSF11B binding to RANKL on osteoblast/stromal cells, blocks the RANKL-RANK ligand interaction between osteoblast/stromal cells and osteoclast precursors. This has the effect of inhibiting the differentiation of the osteoclast precursor into a mature osteoclast.

实验操作小课堂
常见问题解答
化合物如何用于动物实验?如何确立剂量、给药方式等?
同一个化合物对不同动物模型、不同疾病模型的用法不一样,建议根据实验目的,查询文献选择用法。 常见的给药方式包括腹腔注射、灌胃等。由于首过效应,一般可以灌胃的也可以腹腔注射,可以腹腔注射的不一定适合灌胃。不同种属的给药剂量可以根据官网的表格换算。但仅供参考,实际应用中可能未必合适或者准确,尽量以具体某种动物给药剂量的参考文献为主。 我们的化合物都可以进行细胞动物实验,但有些化合物还没有用于动物实验的文献,这种情况下,您可以尝试进行动物实验,但我们无法提供使用方式,也无法保证药效。
如何稀释工作液?
根据您的工作液浓度,计算母液所需要稀释的倍数和所需母液的体积。建议用水、生理盐水、PBS等溶剂进行稀释,如果是细胞实验,可以使用培养基。 取适当的溶剂缓慢加入到母液中,直到达到您的工作液浓度,可以通过涡旋或者移液枪轻轻吹打帮助混匀。 我们的化合物大部分是脂溶性的,所以在使用 PBS 或者培养基等稀释工作液的时候,会有沉淀析出,这些都是正常现象,大多时候可以通过超声完全溶解。 工作液建议现配现用!
溶解度中写的“< 1 mg/mL refers to the slightly soluble or insoluble ”是什么意思?
这句话指的是,如果溶解度 < 1 mg/mL,那我们就认为它是微溶或不溶的,这是针对写的“DMSO:Insoluble”或“DMSO:slightly soluble”这类化合物的。
期货产品没有纯度啊?这个纯度在哪里看
期货产品的话,是没有纯度信息,也没有质检信息的。有了现货之后我们会进行质检,测出试剂的纯度和结构等相关信息,并且展示在官网的活性描述上方。
动物实验常用溶解方法?
首先,您需要确认给药剂量、给药方式。对于具体的产品,优先找引用我们产品的文献里的使用方法,再找其他文献里的配方。 如果没有相关的文献,且该化合物的 DMSO 溶解度比较好,我们推荐通用配方: 10% DMSO+40% PEG300+5% Tween-80+45% Saline/PBS/ddH2O。溶剂依次加入,尽量溶解后再加入下一个溶剂。正常鼠建议 DMSO 浓度在 10% 以下,裸鼠体弱鼠等配方的 DMSO 浓度建议在 2% 以下,根据溶液是否澄清,助溶剂 PEG300、Tween-80 的比例可以适当调整。如果有其他助溶剂也可以使用。 以上配方仅供参考,体内配方并不是绝对的,需要根据不同情况进行调整。建议先取少量化合物测试配方,再进行大量配制。配完也可以再使用超声、加热等方式助溶,看看能不能澄清一点。 腹腔注射对粉末的溶解度要求比较高,建议购买盐形式化合物。如果给药剂量比较大,也有报道使用混悬液进行腹腔给药的。 对于灌胃给药,且剂量比较大的情况下,建议用 0.5% CMC-Na 配置成均匀混悬液进行给药。
