产品描述
This mouse NGAL ELISA kit is suitable for the quantitative determination of mouse NGAL in the serum, plasma, tissue homogenates, or urine. It employs the competitive inhibition enzyme immunoassay technique. The microtiter plate has been pre-coated with NGAL. Standards or samples are added to the appropriate microtiter plate wells with HRP-conjugated antibody preparation specific for NGAL. The competitive inhibition reaction is launched between pre-coated NGAL and NGAL in samples. A substrate solution is added to the wells and the color develops oppositely to the amount of NGAL in the samples. The color development is stopped and the intensity of the color is measured.
NGAL, also called LCN2, is released by neutrophils at sites of infection and inflammation to participate in the antibacterial defense through iron sequestration. NGAL is also responsible for iron delivery to the cytoplasm where it is accumulated and activates or inhibits iron-responsive genes. Iron unloading depends on the cycling of NGAL through acidic endosomes. Devireddy LR et al have shown that NGAL is also involved in apoptosis-dependent deprivation of trophic factors. NGAL is considered the biochemical gold standard for the early diagnosis of acute kidney injury because it is rapidly released after tubular damage.

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 mouse NGAL in various matrices and diluted with the Sample Diluent to produce samples with values within the dynamic range of the assay. | |
