RGMA 重组蛋白, Human (His & Avi), Biotinylated

RGMA Protein, Human, Recombinant (His & Avi), Biotinylated

产品编号 TMPK-00279 RGMA Protein, Human, Recombinant (His & Avi), Biotinylated

Repulsive guidance molecule (RGM) is a glycosylphosphatidylinositol (GPI)-anchored glycoprotein that has diverse functions in the developing and pathological central nervous system (CNS). The binding of RGM to its receptor neogenin regulates axon guidance, neuronal differentiation, and survival during the development of the CNS. RGMa induces T cell activation in experimental autoimmune encephalomyelitis (EAE), which is the animal model of multiple sclerosis (MS).

常见问题解答

问超声应使用什么样的频率？

答频率建议使用常规的超声清洗频率即可，一般在20 kHz - 100 kHz。

问动物实验常用溶解方法？

答首先，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。

问抑制剂母液的储存方式？

答母液配置完成后，一般储存于 -80℃，可以存 1 年以上。建议多分装几管，避免反复冻融，常用的存于 4 度，可放一周以上。

问细胞实验中需要加多少抑制剂？

答通常建议您参考同模型实验发表的文献报道；除参考文献报道以外，还需要通过预实验做“剂量-效应曲线”确定最佳作用浓度（浓度梯度）；通过“时间-效应曲线”确定最佳孵育时间（处理时间梯度）。另外，抑制剂的使用量受多种因素影响，包括抑制对象的可接触性、细胞通透性、孵育时间、细胞种类等等。我们建议通过检索文献确定使用抑制剂的起始浓度。如果有报道的 Ki 值或 IC50 值，可以采用其 5-10 倍的量开始尝试以达到抑制酶活性的最佳效果。如果抑制剂的 Ki 值或 IC50 值未知，则需要在更广泛的范围尝试抑制剂的使用浓度，并采用 Michaelis-Menten 动力学计算 Ki 值。一般设立溶解抑制剂时所采用的溶剂作为对照，以排除溶剂的非特异性影响。

问期货产品没有纯度啊？这个纯度在哪里看

答期货产品的话，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。

产品描述	Repulsive guidance molecule (RGM) is a glycosylphosphatidylinositol (GPI)-anchored glycoprotein that has diverse functions in the developing and pathological central nervous system (CNS). The binding of RGM to its receptor neogenin regulates axon guidance, neuronal differentiation, and survival during the development of the CNS. RGMa induces T cell activation in experimental autoimmune encephalomyelitis (EAE), which is the animal model of multiple sclerosis (MS).
种属	Human
表达系统	HEK293 Cells
标签	C-His-Avi
蛋白编号	Q96B86-1
别名	RGMA,RGM
蛋白构建	Cys48-Gly422
蛋白纯度	> 95% as determined by Tris-Bis PAGE; > 95% as determined by HPLC
分子量	44.5 kDa (predicted). Due to glycosylation, the protein migrates to 45-48 kDa based on Tris-Bis PAGE result.
内毒素	< 1 EU/μg by the LAL method.
缓冲液	Lyophilized from a solution filtered through a 0.22 μm filter, containing PBS (pH 7.4). Typically, 8% trehalose is incorporated as a protective agent before lyophilization.
复溶方法	Reconstitute the lyophilized protein in distilled water. The product concentration should not be less than 100 μg/ml. Before opening, centrifuge the tube to collect powder at the bottom. After adding the reconstitution buffer, avoid vortexing or pipetting for mixing.
存储	It is recommended to store recombinant proteins at -20°C to -80°C for future use. Lyophilized powders can be stably stored for over 12 months, while liquid products can be stored for 6-12 months at -80°C. For reconstituted protein solutions, the solution can be stored at -20°C to -80°C for at least 3 months. Please avoid multiple freeze-thaw cycles and store products in aliquots.
运输方式	In general, Lyophilized powders are shipping with blue ice.
