我对测量人类血浆样本中的皮质类固醇结合球蛋白很感兴趣。我看了一下你们的产品CSB-E14214h,我有一些问题: 1、试剂盒是针对完整的cbg有特异性吗?还是可能与弹性蛋白酶裂解形式有交叉反应?是单抗还是双抗设计?抗体在哪里与蛋白质结合? 2、试剂盒检测到的典型血浆水平是多少? 3、我们需要测量约160个样品,需要多少个这样的ELISA试剂盒?

- Data suggest that some individuals with adrenal insufficiency due to SERPINA6 mutations present with hypotension or nonspecific symptoms such as fatigue, nausea, or chronic pain, but symptomatology varies widely, even between family members with identical mutations. [REVIEW] PMID: 29194043
- In conclusion, site-specific CBG N-glycosylation regulates the bioavailability of cortisol in inflamed environments by fine-tuning the RCL proteolysis by endogenous and exogenous elastases. PMID: 27339896

- Data indicate there was no significant circadian variation in serum cortisol-binding globulin (CBG) concentration in any of the 4 groups. PMID: 26603673
- Human cardiomyocytes express mineralocorticoid receptors, but are mostly free of nuclear glucocorticoid receptors. CBG is expressed in myocardium and in Purkinje fibers. CBG in heart is colocalized with mineralocorticoid receptor. PMID: 25251318

- genetic association studies in Chinese populations: Data suggest that SERPINA6 with SNP (A51V) is poorly produced/secreted; plasma corticosteroid-binding globulin levels in heterozygous subjects for this variant are 50% lower than in normal subjects. PMID: 22337907

- Homozygosity for the serine allele of the CBG gene may predispose to chronic fatigue syndrome, perhaps due to an effect on hypothalamic-pituitary-adrenal axis function related to altered CBG-cortisol transport function or immune-cortisol interactions. PMID: 15554358
- Circulating adiponectin, CBG concentration, and fasting cortisol were significantly interrelated in healthy subjects. A significant sexual dimorphism exists in this association. PMID: 15877287
