  • 精密度：
    Intra-assay Precision (Precision within an assay): CV%<15%      
    Three samples of known concentration were tested twenty times on one plate to assess.  
    Inter-assay Precision (Precision between assays): CV%<15%      
    Three samples of known concentration were tested in twenty assays to assess.    
                 
  • 线性度：
    To assess the linearity of the assay, samples were spiked with high concentrations of human GH2 in various matrices and diluted with the Sample Diluent to produce samples with values within the dynamic range of the assay.

  • 功能：
    Plays an important role in growth control. Its major role in stimulating body growth is to stimulate the liver and other tissues to secrete IGF-1. It stimulates both the differentiation and proliferation of myoblasts. It also stimulates amino acid uptake and protein synthesis in muscle and other tissues.

    1. Type 1 diabetic women delivering large for gestational age infants had lower placental GH levels in early pregnancy. PMID: 26589570
    2. genetic association studies in populations in Estonia, Czech Republic, and Bashkortostan/Russia: Data suggest an SNP in GH2 (rs2006123) is associated with adult height (not body mass index); A-allele is associated with taller stature. [META-ANALYSIS] PMID: 24035309
    3. Maternal serum PGH at 11-13 weeks' gestation is unlikely to be a useful biochemical marker for early prediction of small for gestational age neonates. PMID: 22489624
    4. results are consistent with a pleiotropic effect of placental hGH/CSH genes at the maternal-fetal interface relating to the regulation of fetal growth and the risk of affected maternal metabolism. PMID: 22387044
    5. These results suggest that the normal PGH-IGF-I-IGFBP3 axis in pregnancy is abnormal in Type 1 Diabetic pregnancies. PMID: 22363400
    6. early first trimester maternal serum marker for Down syndrome PMID: 19844941
    7. The hGH-V promoter activity and the endogenous mRNA expression in human placental choriocarcinoma cell line JAR in the presence of glucose and demethylating genome conditions, were compared. PMID: 20005926
    8. GH-V plays a major role in affecting target cells expressing the GH receptor, thus potentially exerting significant GH-like effects on maternal physiology during pregnancy. PMID: 12213191
    9. Data show that improved binding affinity of human growth hormone (hGH(v)) results from numerous small contributions distributed broadly over the interface. PMID: 12946357
    10. Using a mutagenesis-scanning analysis of 81 single and 32 pairwise double mutations, it is shown that the GHv hormone's two spatially distal receptor binding sites (Site1 and Site2) are allosterically coupled PMID: 15563602
    11. results offer the first evidence for a placental role of human placental growth hormone(hPGH) and suggest an autocrine/paracrine role of hPGH in the regulation of trophoblast invasion PMID: 15718272
    12. PGH may play a role in the mechanisms of disease in preeclampsia and fetal growth restriction. PMID: 17701665
    13. Placental growth hormone (PGH) secretion by BeWo cells is regulated by hormonal factors and adipokines. Elevated insulin and leptin levels might down-regulate PGH secretion. PMID: 18356738
