  • 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.
  • 線性度:
    To assess the linearity of the assay, samples were spiked with high concentrations of human PG in various matrices and diluted with the Sample Diluent to produce samples with values within the dynamic range of the assay.

靶點(diǎn)詳情

  • 功能:
    Shows particularly broad specificity; although bonds involving phenylalanine and leucine are preferred, many others are also cleaved to some extent.
  • 基因功能參考文獻(xiàn):
    1. Low Pepsinogen I is associated with precancerous gastric lesions. PMID: 25292040
    2. High serum Pepsinogen I level is associ9ated with the progression of gastric precancerous lesions. PMID: 24895149
    3. Significantly higher AUC was observed for the PGI/PGII ratio and is associated with atrophy and intestinal metaplasia. PMID: 23886209
    4. A significant negative correlation was found between the degree of corpus atrophy and the level of serum pepsinogen-I in atrophic gastritis patients with gastroesophageal reflux. PMID: 21175799
    5. Higher levels of Pepsinogen I is associated with early gastric cancer PMID: 15688378
