Assay Principle
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.
To assess the linearity of the assay, samples were spiked with high concentrations of human GPX1 in various matrices and diluted with the Sample Diluent to produce samples with values within the dynamic range of the assay.

The Human Glutathione peroxidase 1 (GPX1) ELISA kit is suitable for researchers working with human samples. This kit is created to quantitatively measure GPX1 levels in serum, plasma, and tissue homogenates. It can measure GPX1 levels ranging from 15.6 μU/mL to 1000 μU/mL. The sensitivity of the detection is 3.9 μU/mL. The assay is conducted using a sandwich method, namely the GPX1 protein in the sample is captured by capture antibodies and detection antibodies. The assay time ranges from 1 to 5 hours, making it efficient for high-throughput experiments. A small sample volume of 50-100 μl is required for analysis. The detection wavelength is set at 450 nm, optimizing the detection of GPX1 levels in the samples. This ELISA kit has been utilized in more than 10 research papers, showcasing its widespread acceptance and reliability in the scientific community. The kit's ability to accurately measure GPX1 levels has contributed to advancing the understanding of the role of this enzyme in GPX1-associated studies including diabetes, oxidative stress, and cancer.
