Profile: Axiva Sichem Pvt.Ltd specializes in providing filtration products to Research Laboratories. Nitrocellulose Membrane is the most important part of a lateral flow assay and require highly consistent measurements for capillary flow rate and thickness across the length and width. Variation in either can have detrimental effects on assay sensitivity, reproducibility, repeatability in results and reagent consumption (in special assay developments which are controlled by time or volume consumed). Signal generation at the test and control lines is influenced by the thickness of the reaction membrane. The variation in thickness across or down a roll can have negative effects in both the manufacturing in-process approval levels and final assay performance.
