The human mucin-5AC (MUC5AC) ELISA kit is a valuable tool for detecting and quantifying MUC5AC levels in human samples, including serum, plasma, cell culture supernates, and urine. It offers a wide detection range from 15.6 ng/mL to 1000 ng/mL, with a sensitivity of 3.9 ng/mL, making it suitable for accurately measuring MUC5AC concentrations. The assay principle is quantitative, utilizing a sandwich measurement technique that ensures precise results. The assay can be completed within 1-5 hours, requiring a sample volume of 50-100 µl. Detection is performed at a wavelength of 450 nm, providing reliable and reproducible data. This ELISA kit has been utilized in more than 10 publications.
