实验操作小课堂
常见问题解答
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。
是否能直接用缓冲液对抑制剂 DMSO 母液做梯度稀释?
大部分情况下,都是可以溶解的。但有时,有机试剂直接加入水相介质时会析出。建议将抑制剂先以DMSO做梯度稀释,再将经过稀释的抑制剂加入缓冲液或细胞培养基。有些抑制剂甚至只有在其工作浓度下才能溶于水相。 比如细胞实验中希望终浓度为 1 μM 的话,可以把 10 mM 的 DMSO 母液用 DMSO 稀释到 1 mM,再吸 2 μL 加入到 2 mL 的生理盐水/PBS/细胞培液,终浓度即为 1 μM。 为避免药物析出,稀释前,可将母液和培养基 37℃ 预热,避免温度低造成严重析出。若稀释过程中出现化合物析出的情况,建议您采用超声加热的方法使其复溶。
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。
得到的杀死细胞的 IC50 与网页上 IC50 差距较大怎么办?
您所测试的IC50是指细胞的增殖抑制实验(半抑制率),细胞增殖抑制实验 IC50值,和网页上的靶点IC50其实是不同的意义。文献里和网页上 IC50其实往往是指对于靶点无细胞实验的抑制率,这样的实验一般是通过激酶或者蛋白纯化实验做出来的,nM 级别的浓度比较常见,但是细胞的增殖抑制实验 IC50 是指细胞的半致死率,同时牵涉到细胞的代谢以及渗透,一般浓度会高一些。 另外,同一个化合物对不同细胞模型的效果也是不同的,建议尝试增加孵育量、延长孵育时间。
收到产品发现冰盒都化了,怎么办?
一般化合物粉末对温度不敏感,加冰盒是为了防止极端气温,如果冰盒融化不影响产品质量。

缓冲液Lyophilized from a solution filtered through a 0.22 μm filter, containing 20 mM Tris, 500 mM NaCl, pH 7.4, 10% gly. 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
TLR2, also known as CD282, is a member of the Toll-like receptor (TLR) family. TLRs are highly conserved from Drosophila to humans and share structural and functional similarities. They play a fundamental role in pathogen recognition and activation of innate immunity. They recognize pathogen-associated molecular patterns (PAMPs) that are expressed on infectious agents, and mediate the production of cytokines necessary for the development of effective immunity. The various TLRs exhibit different patterns of expression. TLR2 contains 14 LRR (leucine-rich) repeats and 1 TIR domain. TLR2 gene is expressed most abundantly in peripheral blood leukocytes, and mediates host response to Gram-positive bacteria and yeast via stimulation of NF-kappaB. CD282 cooperates with LY96 to mediate the innate immune response to bacterial lipoproteins and other microbial cell wall components. It also cooperates with TLR1 to mediate the innate immune response to bacterial lipoproteins or lipopeptides. CD282 acts via MYD88 and TRAF6, leading to NF-kappa-B activation, cytokine secretion and the inflammatory response. It may also promote apoptosis in response to lipoproteins.
