  • 精密度：
    Intra-assay Precision (Precision within an assay): CV%<8%        
    Three samples of known concentration were tested twenty times on one plate to assess.    
    Inter-assay Precision (Precision between assays): CV%<10%        
    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 SPP2 in various matrices and diluted with the Sample Diluent to produce samples with values within the dynamic range of the assay.

  • 基因功能参考文献：
    1. Spp24 can inhibit the growth of prostate cancer and its bone metastasis induced by BMP2; spp24 may have great potential to be a therapeutic agent in clinical situations PMID: 27793899
    2. the two mutations of SPP2 have dominant negative effects and cellular accumulation of Spp-24 might be particularly toxic to photoreceptors and/or retinal pigment epithelium. SPP2 has a new role in retinal degeneration. PMID: 26459573
    3. Report describes a C-terminal fragment within SPP24 that is distinct from the cystatin domain and which independently binds to BMP-2 and TGF-beta. This fragment inhibited BMP-2 activity in an ectopic bone forming assay. PMID: 25418420
    4. Spp24, or proteolytic products of Spp24, bind cytokines of the TGF-beta superfamily and also activate intracellular signaling pathways [review] PMID: 25339413
    5. Spp24 truncation products have effects on osteoblastic differentiation mediated by kinase pathways that are independent of exogenous BMP/TGF-beta cytokines. PMID: 25501958
    6. Results describe the localization of the human secreted phosphoprotein 24 gene, its structure and the start of transcription in liver. PMID: 15062857
    7. spp24 contains at least 2 single nucleotide polymorphisms. Given its mechanism of action and sequence variability, SPP24 may be an interesting candidate for future studies of the genetic regulation of bone mass. PMID: 19375587
