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

产品编号 TMPK-00340

Brain metastasis (BM) in non-small-cell lung cancer (NSCLC) has a very poor prognosis. Recent studies have demonstrated the importance of cell adhesion molecules in tumor metastasis.Elevated levels of ALCAM expression promote BM formation in NSCLC through increased tumor cell dissemination and interaction with the brain endothelial cells. Therefore, ALCAM could be targeted to reduce the occurrence of BM. ALCAM Protein, Human, Recombinant (His & Avi), Biotinylated is expressed in HEK293 mammalian cells with C-His-Avi tag. The predicted molecular weight is 58.9 kDa and the accession number is Q13740-1.

常见问题解答
如何选择合适的溶剂?
常用的溶剂包括DMSO、水、乙醇等。建议您根据抑制剂给出的溶解度参考,选择合适的溶剂。如果该抑制剂可以溶于DMSO,建议使用没有吸潮新开封的 DMSO,如果有潮气污染,很容易带来抑制剂降解或难溶的问题。如果该抑制剂可以溶于水,建议您根据实验类型选择无菌水、生理盐水、无菌 PBS 、培养基等作为溶剂。
加药后检测结果没有作用,是不是产品质量有问题?
产品质量没有问题,都是经过两次严格质检的,HNMR确定产品结构,HPLC确定化合物纯度。同一个抑制剂由于实验材料(细胞、动物)的不同,IC50 和实验效果也是不一样的,不能照搬文献报道的方法,应该根据自己的实验设立浓度梯度,得到一个最适合的浓度。
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。
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。
收到粉状试剂粘壁严重,如何处理?
建议您用离心机 3000 rpm下离心一会儿,将粉末收集到管底。

分子量58.9 kDa (predicted). Due to glycosylation, the protein migrates to 72-80 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.
