- BackgroundVascular endothelial growth factor receptor 1 (VEGFR1) is also known as Fms-like tyrosine kinase 1 (FLT-1), Tyrosine-protein kinase receptor FLT, is a single-pass type I membrane protein and secreted protein which belongs to the protein kinase superfamily, Tyr protein kinase family and CSF-1/PDGF receptor subfamily. VEGFR1 is detected in normal lung, but also in placenta, liver, kidney, heart and brain tissues and specifically expressed in most of the vascular endothelial cells, and also expressed in peripheral blood monocytes. VEGFR1 acts as a cell-surface receptor for VEGFA, VEGFB and PGF, and plays an essential role in the development of embryonic vasculature, the regulation of angiogenesis, cell survival, cell migration, macrophage function, chemotaxis, and cancer cell invasion. VEGFR1 may play an essential role as a negative regulator of embryonic angiogenesis by inhibiting excessive proliferation of endothelial cells. VEGFR1 can promote endothelial cell proliferation, survival and angiogenesis in adulthood.

辣根过氧化物酶(Horseradish Peroxidase,HRP)比活性高,稳定,分子量小,纯酶容易制备,所以最常用。HRP广泛分布于植物界,辣根中含量高,它是由无色的酶蛋白和棕色的铁卟啉结合而成的糖蛋白,糖含量18%。HRP由多个同功酶组成,分子量为40,000,等电点为PH3~9,酶催化的最适PH因供氢体不同而稍有差异,但多在PH5左右。酶溶于水和58%以下饱和度硫酸铵溶液。HRP的辅基和酶蛋白最大吸收光谱分别为403nm和275nm,一般以OD403nm /OD275nm的比值RZ(德文Reinheit Zahl)表示酶的纯度。高纯度的酶RZ值应在3.0左右(最高可达3.4)。RZ值越小,非酶蛋白就越多。 1) RZ>3 活性 >250u/mg, 主要应用于免疫学,是高纯度的过氧化酶。采用特殊色谱纯化技术以除去会影响免疫学反应的同工酶B .
2) RZ>2 活性 >180u/mg ,主要应用于临床化学,我们的客户也有将这个规格的产品应用于免疫学研究的。此时,一个标准化的分析方法就变得尤为重要。
3) RZ>1 活性 >100u/mg,主要应用于血糖试纸和尿液分析试纸。
4) RZ>0.6 活性 >60u/mg ,主要应用于尿液分析试纸。向左转|向右转
1.若都为正常,那么并未有太大问题,只要定期复查就可以了。
2.如果TGAb、TMAb、甲状腺功能均高,那么就是桥本氏甲状腺炎并甲亢,需要抗甲亢治疗。
3.如果TGAb、TMAb高,甲状腺功能下降,那么就是桥本氏甲状腺炎并甲减,需要进行甲减治疗。
4.如果TGAb、TMAb高,甲状腺功能正常,那么就是桥本氏甲状腺炎,无需特殊治疗,只要定期复查甲状腺功能就可能以了,不过这种情况有可能以后演变成甲减或者甲亢。
BAS-ELISA是在常规ELISA原理的基础上,结合生物素(B)与亲和素(A)间的高度放大作用,而建立的一种检测系统。生物素很易与蛋白质(如抗体等)以共价键结合。这样,结合了酶的亲和素分子与结合有特异性抗体的生物素分子产生反应,既起到了多级放大作用,又由于酶在遇到相应底物时的催化作用而呈色,达到检测未知抗原(或抗体)分子的目的。
