  1. Osteopontin
    Rating
    100%
    We ran 3-D cell culture supernatants were run with the kit for the first time as feasibility. We had two different media formulations as background against the culture conditions over a month long culture period. A 3x dilution worked adequately.

  2. ELISA for human PBMC
    Rating
    80%
    We used this kit to detect OPN production levels after stimulating human PBMCs with LPS. OPN production was well detected in a two-fold-diluted culture medium.

  3. ELISA for pancreatic plasma samples
    Rating
    80%
    We used this kit for OPN detection in plasma samples. Overall, the calibration and sensitivity of the assay meet the expectations. However, we had to use low diluted plasma samples to be able to detect levels of OPN. So, dilution optimization will be most likely required before running higher number of samples.
