武汉费斯德生物科技有限公司, NewEast Biosciences 中国办事处
武汉费斯德生物科技有限公司是美国NewEast Biosciences在中国的办事处。NewEast Biosciences 在十二年前率先研发俩种独特的抗体。这俩种抗体仅仅识别活性的GTP酶或者突变的Oncogene。 GTP酶涉及(1)响应细胞表面受体激活的信号转导,包括跨膜受体,例如介导味觉、嗅觉和视觉的那些,(2)核糖体的蛋白质生物合成,(3)调节细胞分化、增殖、分裂和运动,(4)蛋白质通过膜的易位,(5)细胞内囊泡的运输,以及囊泡介导的分泌和摄取,通过GTP酶控制囊泡外壳组装。Oncogene侧是诱发癌症的基因。
我公司将向你提供以下的独一无二的三种抗体或者试剂盒: (1) 仅识别 GTP酶的活性构型的产品, 它可以让你能够量化GTP酶在细胞中的活性和分布。(2) 识别突变 Oncogene蛋白, 但不认识相应野生型的抗体。 (3) 对 cAMP 和 cGMP 具有超亲和力(无需乙酰化)ELISA检测试剂盒。这些产品被将近一千篇同行评议的文章所引用。

Introduction: Small GTPases are a super-family of cellular signaling regulators. Sar1 is a member of these small GTPases. Sar1 functions as a molecular switch to control protein–protein and protein–lipid interactions that direct vesicle budding from the ER. |
Amino Acid Sequence (1-198) |

Properties |
Physical Appearance (form): Dissolved in 20mM Tris-HCl, pH8.0, 150mM NaCl. |
Physical Appearance (form): White or clear |
Concentration: 1 mg/mL |
Storage: -80°C |
Preparation Instructions: Centrifuge the vial before open the cap and reconstitute in water. Adding of 10 mM β-mercaptoethanol or 1 mM DTT into the solution to protect the protein is recommended and using of non-ionic detergents such as n-Dodecyl β-D-maltoside (DoDM) or polyethylene detergents (e.g. C12E10) also help to stabilize the protein. Avoid repeated freezing and thawing after reconstitution. The purity of His-tagged Sar1a was determined by SDS- PAGE and Coomassie Brilliant Blue Staining. |
