| 背景说明 | K-Ras belongs to the small GTPase superfamily，Ras family.As other members of the Ras family，K-Ras is a GTPase and is an early player in many signal transduction pathways.It is usually tethered to cell membranes because of the presence of an isoprenyl group on its C-terminus.K-Ras functions as a molecular on/off switch.Ras proteins bind GDP/GTP and possess intrinsic GTPase activity.Plays an important role in the regulation of cell proliferation.Plays a role in promoting oncogenic events by inducing transcriptional silencing of tumor suppressor genes (TSGs) in colorectal cancer (CRC) cells in a ZNF304-dependent manner.Besides essential function in normal tissue signaling，the mutation of a K-Ras gene is an essential step in the development of many cancers.Several germline K-Ras mutations have been found to be associated with Noonan syndrome[4] and cardio-facio-cutaneous syndrome.Somatic K-Ras mutations are found at high rates in Leukemias，colon cancer，pancreatic cancer and lung cancer. |

文献和实验Secretion of Recombinant Human Insulin-Like Growth Factor I (IGF-I)
The development of efficient recombinant protein production processes can be a critical factor in whether or not a pharmaceutical therapeutic protein can enter human clinical trials and ultimately the marketplace. This is especially true
In this chapter we describe efficient procedures for the construction, expression and screening of comprehensive libraries of human Fab antibody fragments displayed on the surface of filamentous phage. Phagemid vectors are used for placing
我们知道，PeproTech的所有细胞因子和蛋白均为冻干粉，这使得运输非常便捷，只要常温即可。而且，细胞因子和蛋白冻干粉非常稳定，在-20℃或-80℃条件下可保存数年。冻干粉在使用前需进行溶解，然后以液体形式加到培养体系或注射入动物体内。溶解步骤非常关键，因溶解不好会导致细胞因子或蛋白的失活，这也是很多用户在实际使用中经常遇到的问题。 那么，应该如何进行正确的溶解呢？ 下面我们以Recombinant Human IL-4 (重组人IL-4，产品编号：200-04)的说明书为例
