Sequence analysis shows that the homology of Xinong Saanen Goat FAS gene promoter with bovine and homo is over 90%, there are several potential transcription factor binding sites such as SP1、Ets、LSF.
2.对克隆得出的启动子序列进行生物信息学分析,表明羊FAS基因启动子和牛、人FAS启动子存在90%以上同源性,启动子还存在数个潜在SP1、Ets、LSF等转录因子结合位点。

The union of the transcription factor and corresponding binding sites has the high specificity.
转录因子与其结合位点的结合具有高度的专一性。
Objective: to predict the promotor position and transcription factor binding sites of human BMP-2 gene.
目的:预测人类BMP - 2基因启动子位置和可能的转录因子结合位点。
But metal canons have stronger affinity to the binding sites and higher ability of regeneration than neutral red has.
但金属离子与结合位点具有更强的亲和力,使蓝膜再生为紫膜的能力比质子化中性红强。
So, now you have a single molecule, very large molecule, with not just two binding sites but with ten binding sites.
所以如果你体内有一个细胞,一个体积很大的细胞,细胞表面不只有两个抗原结合位点,而有十个抗原结合位点
The advantage of this is that now you have four binding sites for antigen instead of just two.
这样的好处是一个抗体上,有四个抗原结合位点而不仅仅是两个
So, these are better at binding to antigen because they have more binding sites on them.
连接抗体是对付抗原的有效方法,因为抗体表面将会有更多的抗原结合位点
