实验操作小课堂
常见问题解答
母液配置的计算方法?
(1) c=n/v=m/M/v 浓度=物质的量/体积=质量/相对分子质量/体积 (2) 官网产品详情页下方有溶液配制表格,可以参考计算好的加入溶剂体积
购买多次产品,发现颜色不同,怎么办?
首先请您确认批次,如果是同一个批次产品,请联系技术同事核查产品颜色。如果是不同批次,请您放心,颜色不同可能是生产工艺不同而造成的,生产过程中的操作、温度、时间等因素可能会影响产品的颜色。如果您对该批次有疑虑,可在官网下载相应的质检报告,我们是对产品质量负责的。
超声应使用什么仪器?
建议使用“超声清洗仪”,不推荐用“超声破碎仪”。
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。
产品溶解需要超声吗?如果没有超声仪怎么办?
超声可以加快粉末的溶解速度,如果您的化合物溶解不了,建议您尝试超声。如果您没有超声仪,建议您选择较低母液浓度,或者较少粉末量,尝试溶解。

缓冲液Lyophilized from a solution filtered through a 0.22 μm filter, containing PBS, pH 7.4. Typically, a mixture containing 5% to 8% trehalose, mannitol, and 0.01% Tween 80 is incorporated as a protective agent before lyophilization.
复溶方法
A Certificate of Analysis (CoA) containing reconstitution instructions is included with the products. Please refer to the CoA for detailed information.
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.
研究背景
Cripto/TDGF1 is a member of the epidermal growth factor (EGF)- Cripto, Frl-1, and Cryptic (CFC) family. EGF-CFC family member proteins share a variant EGF-like motif, a conserved cysteine-rich domain, and a C-terminal hydrophobic region. Before gastrulation, Cripto is asymmetrically expressed in a proximal–distal gradient in the epiblast, and subsequently is expressed in the primitive streak and newly formed embryonic mesoderm. These proteins play key roles in intercellular signaling pathways during vertebrate embryogenesis. Mutations in Cripto/TDGF1 can cause autosomal visceral heterotaxy. Cripto/TDGF1 is involved in left-right asymmetric morphogenesis during organ development. Cripto signalling is essential for the conversion of a proximal–distal asymmetry into an orthogonal anterior–posterior axis. The mechanism of inhibitory effects of the Cripto includes both cancer cell apoptosis, activation of c-Jun-NH(2)-terminal kinase and p38 kinase signaling pathways and blocking of Akt phosphorylation. Thus, Cripto is a unique target, and Immunohistochemistry to Cripto could be of therapeutic value for human cancers.
