  • 测定方法:
  • 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 rat IGFBP-1 in various matrices and diluted with the Sample Diluent to produce samples with values within the dynamic range of the assay.

  • 功能:
    IGF-binding proteins prolong the half-life of the IGFs and have been shown to either inhibit or stimulate the growth promoting effects of the IGFs on cell culture. They alter the interaction of IGFs with their cell surface receptors. Promotes cell migration (By similarity).
