MPZL1 Protein, Human, Recombinant (His)

产品编号 TMPJ-00712 MPZL1 Protein, Human, Recombinant (His)

Myelin protein zero-like protein 1(MPZL1) is encoded by the MPZL1 gene, which is a single-pass type I membrane protein. It is widely expressed with highest levels in heart, placenta, kidney and pancreas. As cell surface receptor, it involved in signal transduction processes. MPZL1 recruits PTPN11/SHP-2 to the cell membrane and subsequently activate/phosphorylate Src kinase at Tyr426, promoting phosphorylation of cortactin and migration of HCC cells. MPZL1also is a major receptor for concanavalin-A (ConA) and involved in cellular signaling induced by ConA, which probably includes Src family tyrosine-protein kinases.

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。

问抑制剂产品应如何储存？

答粉末储存在 -20℃，可以存 3 年以上。母液一般储存于 -80℃，可以存 1 年以上，建议多分装几管，避免反复冻融。常用的存于 4℃，可放一周以上。

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。
