PSG6 Protein, Human, Recombinant (His)

产品编号 TMPY-02891 PSG6 Protein, Human, Recombinant (His)

PSG6 is a pregnancy-specific glycoprotein(PSG). PSGs are secreted proteins produced by the rodent and primate placenta and play a critical role in pregnancy success. The levels of PSGs are highest during the third trimester of pregnancy, a time marked by the most profound suppression of MS disease attacks. PSGs regulate T-cell function. The regulation of T-cell function during pregnancy is likely the result of significant hormonal changes and may well involve immunoregulatory proteins derived from the placenta. Pregnancy specific glycoproteins (PSGs) are the most abundant placentally derived glycoproteins in the maternal serum. PSG1, PSG6, PSG6N, and PSG11 induce dose-dependent secretion of anti-inflammatory cytokines by human monocytes. Human and murine PSGs exhibit cross-species activity.

常见问题解答

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。

问抑制剂是否需要灭菌？

答如果您使用 DMSO 配制：不建议灭菌，DMSO 本身具有极强的杀菌力，配制好的溶液就是无菌溶液。如果您确实担心的，可以放置 4℃ 冰箱过夜放置即可；依然有顾虑的话，需用有机系专用滤膜过滤。如果您使用水配制：可以用 0.22 μm 滤膜过滤灭菌。

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

问准备进行动物实验，收到大包装粉末后，如何分装溶解？

答根据配制出来的溶液是不是澄清的确定一次性能配多少：如果配制出来是澄清溶液，可以一次性多配制一些，储存于4度冰箱，大概一周配一次，放久了可能会失效；如果配制出来是混悬液，建议每次使用的时候都现配现用。

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.
