Preparation of sgp130 ELISA kit and its application / 中国免疫学杂志

ABSTRACT

Objective:To establish the sensitive,specific,stable and convenient sgp130 ELISA kit.Methods:The mAb T2 against human gp130 was used as coating antibody;the other mAb T12 recognized different epitope with T2 was labeled by biotin,then a ELISA kit for detecting sgp130 was set up.Results:sgp130 ELISA kit is successfully established and its sensitivity is 10 ng/ml.After the kit is placed in 4℃ for 3 months,the kit's CV is less than ?7.6% and the retrievable rate is 95%～111%.These indicate that it has highly sensitivity,stability and accuracy.The normal serum concentration of sgp130 in healthy donors is 536.92～287.88(ng/ml),but there is higher in patients with hyperthyroidism(937.16?217.5) and chronic nephritis(806.45?138.47).Significant difference is found comparing with normal control(P
