Problems solved by technology

However, we found in experiments that although these kits can detect the levels of BMP2 and Noggin in cell culture supernatants, they are difficult to detect in serum. The reason is that the levels in serum are low and the tolerance range of the kits is difficult to reach this level

Abstract

The invention discloses application of BMP2 and Noggin in jointly preparing an ankylosing spondylitis diagnostic reagent kit.The invention further discloses application of BMP2 and Noggin in jointly preparing a reagent kit for predicting the severity of ankylosing spondylitis pathologic osteogenesis.The invention further discloses a BMP2 detection reagent kit and a Noggin detection reagent kit.By detecting the BMP2 level and the Noggin level at the same time, the specificity and sensitivity of diagnosis of ankylosing spondylitis can be improved, and the severity of ankylosing spondylitis pathologic osteogenesis can be predicted.By means of the BMP2 detection reagent kit and the Noggin detection reagent kit, the lower limit of the reagent kit detection allowable range is lowered, and the detection accuracy is improved.

Description

technical field [0001] The invention belongs to the medical and health field, and particularly relates to the application of BMP2 and Noggin in the preparation of an ankylosing spondylitis diagnostic kit. Background technique [0002] AS is a common autoimmune disease with a high prevalence rate of about 0.2-0.54% in my country (see: Rong, J.G. Jieruo, Spondyloarthritisinchina. CurrOpinRheumatol, 2013.25(4): p.460-7. ). AS tends to occur in young men and often involves the axial joints. The main clinical and pathological features are chronic progressive inflammation and pathological osteogenesis (see: Braun, J.J. Sieper, Ankylosingspondylitis. Lancet, 2007.369(9570): p.1379 -90.). However, the pathogenesis of AS is still unclear, which leads to the limitations and low effectiveness of current AS diagnosis and treatment methods. As the disease progresses, AS patients will gradually lose their ability to live and work, which brings heavy psychological pressure and economic b...
