Based on sandwich ELISA assay BT LAB's developed One-Step ELISA assay to be more simple. Unlike conventional sandwich ELISA, without diluting, add the sample directly into the well,One-Step ELISA kits generate data within just 90 minutes. All serum or plasma-based targets are tested and fall within World Health Organization blood reference ranges. The dynamic detection range is relatively wide, and the sample values can basically fall within the range of the calibration, so the sample can be directly loaded.Click below to see more details.
