Notch 4 Protein, Mouse, Recombinant (His)

产品编号 TMPK-00868

The Notch signaling pathway is important for cell-cell communication; it is involved in gene regulation mechanisms that control multiple cell differentiation processes during embryonic and adult life. Notch-4 expression correlates with Ki67. Notch-4 also plays a key role in breast cancer stem-like cells.

实验操作小课堂
常见问题解答
产品是否需要避光?
一般来说,如果有需要避光储存的分子,我们会选择棕色玻璃瓶发货的。
溶解度写的“mg/mL”和“mM”是什么意思?
mg/mL 与 mM,是两种不同单位的表示方式,所指代的最大溶解度是一样的,可以通过官网网页下方的摩尔浓度计算器进行换算
动物不能耐受 DMSO,给药时 DMSO量应该如何控制?
对于普通的老鼠,DMSO 的浓度应控制在 10% 以下,对于裸鼠、转基因小鼠、耐受性弱的老鼠等,DMSO 浓度需控制在2%以下。对于首次操作的抑制剂,建议先做溶剂阴性对照,确认溶解对动物无非特异性影响。
细胞实验中需要加多少抑制剂?
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。
细胞实验中,抑制剂如何溶解?
用 DMSO 配置较高浓度母液,母液存于 -80℃,建议多分装几管,一周内使用的存于 4℃,避免反复冻融。实验时用 pbs、生理盐水、培养基、水这些稀释,细胞实验DMSO的终浓度不超过 0.1%。如果超过 0.1%,则需要在做预试验的时候,先进行溶剂阴性对照实验,排除溶剂对细胞的影响。
