USAGE
Reconstitute in sterile PBS, pH7.2-pH7.4.
STORAGE AND STABILITY
Storage: Avoid repeated freeze/thaw cycles. Store at 2-8oC for one month. Aliquot and store at -80oC for 12 months.
Stability Test: The thermal stability is described by the loss rate of the target protein. The loss rate was determined by accelerated thermal degradation test, that is, incubate the protein at 37oC for 48h, and no obvious degradation and precipitation were observed. (Referring from China Biological Products Standard, which was calculated by the Arrhenius equation.) The loss of this protein is less than 5% within the expiration date under appropriate storage condition.

一、CA125检测的特征 CA125的测定属肿瘤标志物的检测方法，完全不同于由绒毛分泌的绒毛促性腺激素hCG具有极高的特异性与敏感性，因而需要了解其原理才能很好的应用于临床。肿瘤没有特异性抗原，只有肿瘤相关抗原，因之特异性差。 1981年美国科学家Bast以卵巢上皮癌细胞株（ovarian carcimoma antigen,OVCA433）为抗原制备了单克隆抗体OC125，OC125所识别的抗原称为CA125（carcimoma antigen,CA125
。 迄今为止，卵巢癌诊断与监测最重要的标志物是CA125和HE4，它们也是目前仅有的两种获美国食品药品管理局（FDA）批准作为卵巢癌监测的标志物。 但是研究显示：单独使用CA125这一肿瘤标志物在卵巢癌早期诊断的检出率不高，敏感度与特异度较低，导致出现假阴性或假阳性。 2003年，研究人员将基因与蛋白质组技术相结合，筛选出新的肿瘤标志物HE4，并证明HE4对卵巢癌诊断具有重要参考价值，而且在早期诊断中优于CA125。 新的肿瘤标志物HE4
