PDGF R alpha/PDGFRA Protein, Human, Recombinant (His & Avi)

产品编号 TMPK-00419 PDGF R alpha/PDGFRA Protein, Human, Recombinant (His & Avi)

Platelet-derived growth factor is commonly known as a mitogen. Many research data suggest a role for PDGF-beta R in the mitogenic response of mesangial cells. There are four members of PDGF family known as PDGF-A chain, PDGF-B chain, PDGF-C chain and PDGF-D chain, which in active forms are dimers. As far as two receptors PDGF-alpha R and PDGF-beta R are known to bind PDGF. PDGF R alpha/PDGFRA Protein, Human, Recombinant (His & Avi) is expressed in HEK293 mammalian cells with C-His-Avi tag. The predicted molecular weight is 59.2 kDa and the accession number is P16234.

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。

问母液配置的计算方法？

答（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

问PEG300 可以用 PEG400 替代吗？

答PEG300 具有适度的粘稠度，有利于药物的溶解和给药过程，同时也能够提供良好的耐受性，不会对动物造成不良影响。PEG400 可以替代 PEG300。 PEG600 不是很建议，因为熔点接近常温。

问得到的杀死细胞的 IC50 与网页上 IC50 差距较大怎么办？

答您所测试的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。

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.
