Human CD147 (EMMPRIN, Basigin) is a transmembrane glycoprotein expressed more intensely on thymocytes than on mature peripheral blood T cells. Expression of CD147 in bronchial epithelial cells has been correlated with incidence of COPD(3).
Isotype: Murine IgG1
Immunogen: Human T cell line Molt 13
Specificity: Antibody UM-8D6 recognizes extracellular epitope 2 within the n-terminal Ig domain (1) of the human CD147 molecule, about 35-40 kd (2)
Functional Applications: UM-8D6 inhibits homotypic aggregation, adhesion to matrix proteins and migation through matrigel (1). This antibody can inhibit homotypic induction of MMP (Matrix metalloproteinase), as well as cyclophilin mediated chemotactic resposes (4). It has been shown to inhibit proliferation of stimulated T cells in vitro (7). UM-8D6 is recommended for use in Western blot at 0.1 - 1 ug/ml (5). It works on acetone fixed frozen section IHC (6).

核酸是天然高分子化合物,,糖类中的多糖(淀粉、纤维素、糖原等)也是天然高分子化合物
同属于生命的六大营养物质(水,无机盐,糖类,脂质,核酸,蛋白质)
1.CA15-3属于多形上皮黏蛋白。CA15-3测定广泛用于乳腺癌的辅助诊断。60%~80%进展期乳腺癌患者的CA15-3浓度大30kU/L。CA15-3有助于判断肿瘤的进展和疗效,测定值大于1000kU/L者预后不良。在乳腺癌初期其灵敏度较低,在Ⅲ期时约为12%,因此CA15-3测定不能用作乳腺癌的筛选手段.当怀疑乳腺癌而CA15-3又正常时,可以结合CEA值进行考虑。应注意到治疗后由于肿瘤细胞死亡,CA15-3起初会升高,然后才逐渐下降。持续不降或上升者则提示病情恶化。
2.其他恶性肿瘤,如肺、结肠、胰腺、肝脏、卵巢癌、子宫颈和子宫内膜的恶性肿瘤也都可见到CA15-3不同程度的阳性率(低于10%)。
3.肝硬化、肝炎、结节病、结核病、自身免疫性疾病(SLE)以及卵巢、乳腺的良性病变中,CA15-3值略高于正常范围,但阳性率一般低于10%,妊娠中后期,有近一半孕妇血清CA15-3升高。
还有如果用气相做糖的鉴别的话,需要样品量大不大?怎么衍生化?
不好意思,我是学药分的,对植化比较外行,请详细些,谢了先!
一般情况下同时测定蔗糖、果糖和葡萄糖。
选用哪种检测器呐。
本来经战友的意见已决定用示差了,但突然有个经销商愿意以比较优惠的价格卖蒸发光给我们,所以又开始犹豫了。
最后一次请教各位战友,如题目。谢谢!!
