We developed a rapid and simple method for estimating tissue elastin content by measuring desmosine (D) in tissue hydrolysates by competitive ELISA. We compared the ELISA previously reported HPLC methods. When D or isodesmosine (ID) in hydrolysate of the same elastin preparation were measured by the two different methods, a good linear relationship was obtained (r = 0.854 for human aorta or r = 0.938 for rabbit aorta, respectively). The ELISA method can detect as little as 6 pmol/ml and it may be useful in monitoring elastin metabolism in patients with various connective tissue diseases.
我们开发了一种快速简便的方法,通过竞争性酶联免疫吸附测定法(ELISA)测量组织水解产物中的锁链素(D)来估计组织弹性蛋白含量。我们将该ELISA方法与先前报道的高效液相色谱法(HPLC)进行了比较。当用两种不同方法测量同一弹性蛋白制剂水解产物中的D或异锁链素(ID)时,获得了良好的线性关系(人主动脉的r = 0.854,兔主动脉的r = 0.938)。ELISA方法的检测下限低至6 pmol/ml,可能有助于监测各种结缔组织疾病患者的弹性蛋白代谢。
