背景介绍：
人绒毛膜促性腺激素(HCG)是胎盘分泌的一种糖蛋白激素。在正常妊娠期间，血清和尿液中的这种激素水平逐渐升高，直到怀孕8周左右。HCG有两个亚基，即α和β。α亚单位类似于垂体前叶糖蛋白激素的α亚单位，即LH、促甲状腺激素和促卵泡激素。然而，这些激素的β亚基是不同的。因此，这种独特性将一种激素与另一种激素区分开来，从而产生特异性。在制备这种单克隆抗体时，所用的免疫原是βhCG，这有助于使DBC检测系统具有很高的特异性和敏感性。
Human chorionic gonadotropin (hCG) is a glycoprotein hormone produced by the placenta. During normal pregnancy the level of this hormone in serum and urine gradually increases up to about the eighth week of pregnancy. hCG has two subunits, namely α and β. The α subunit is similar to the α subunit of the anterior pituitary gland glycoprotein hormones, namely, LH, TSH and FSH. However, the β subunits of these hormones are different. Therefore, this uniqueness distinguishes one hormone from the other, hence specificity. In raising this monoclonal antibody, the immunogen used was βhCG, which helps to make the DBC assay system very specific and sensitive.
