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。

产品全名: 人 Noggin (C-Fc) 蛋白 |
规格: 10/50/100 µg |
基因符号 Noggin;NOG |
目标蛋白: Noggin |
UNIPROT ID: Q13253 |
描述: Recombinant Human Noggin is produced by our Mammalian expression system and the target gene encoding Gln28-Cys232 is expressed with a Fc tag at the C-terminus. |
背景: Noggin is a secreted homodimeric glycoprotein that is an antagonist of bone morphogenetic proteins (BMPs). Mature Human Noggin contains an N-terminal acidic region, a central basic heparin-binding segment and a C-terminal cysteine-knot structure. Noggin is very highly conserved among vertebrates, such that mature human Noggin shares 99%, 99%, 98%, 97% and 89% aa sequence identity with mouse, rat bovine, equine and chicken Noggin, respectively. Secreted Noggin probably remains close to the cell surface due to its binding of heparin-containing proteoglycans. Noggin binds some BMPs such as BMP4 with high affinity and others such as BMP7 with lower affinity. It antagonizes BMP bioactivities by blocking epitopes on BMPs that are needed for binding to both type I and type II receptors. Noggin is expressed in defined areas of the adult central nervous system and peripheral tissues such as lung, skeletal muscle and skin. During culture of human embryonic stem cells (hESC) or neural stem cells under certain conditions, addition of Noggin to antagonize BMP activity may allow stem cells to proliferate while maintaining their undifferentiated state, or alternatively, to differentiate into dopaminergic neurons. |
物种/宿主: HEK293 |
分子量: 50.2 KDa |
分子特征: Not available |
纯化: Greater than 95% as determined by reducing SDS-PAGE. |
Formulation & Reconstitution: Lyophilized from nanodisc solubilization buffer (20 mM Tris-HCl, 150 mM NaCl, pH 8.0). Normally 5% – 8% trehalose is added as protectants before lyophilization. |
储存和运输: Store at -20°C to -80°C for 12 months in lyophilized form. After reconstitution, if not intended for use within a month, aliquot and store at -80°C (Avoid repeated freezing and thawing). Lyophilized proteins are shipped at ambient temperature. |
