Cytiva, VIV1402550R, Vivid lateral-flow nitrocellulose membranes

Vivid 140 LFNC, 25 mm × 50 m
Nitrocellulose membranes are the heart of lateral-flow assays and require highly consistent wicking rate and thickness for optimized assay sensitivity, reproducibility, and reagent consumption. Vivid lateral-flow nitrocellulose (LFNC) membranes are manufactured to ensure that these key parameters are tightly controlled.
• Coefficients of variation (CV) between 5 and 10%
• Designed for assay reproducibility and sensitivity - High sensitivity with dilute concentrations of target analytes.
• Strong consistency and high duplication rate - When measuring intra- and inter-lot performance for wicking time and thickness Vivid LFNC membranes provide consistent results, resulting in low defined coefficients of variation.
• Clear surface appearance - Controlled surface quality of the membrane ensures freedom from visual defects, discoloration and dust.
• Clear results - Demonstrates low background levels which enable crisp capture lines and easy-to-read results.
Nitrocellulose is the globally preferred membrane substrate in point-of-care diagnostic tests where antigen-antibody binding occurs, e.g., pregnancy tests, urine-albumin tests, and C-reactive protein (CRP) detection. Vivid LFNC membranes fulfill all the criteria to enable the development and manufacture of a diverse range of tests with reliability and reproducibility. Vivid LFNC membranes are designed and tested specifically for diagnostic applications to ensure the materials meet stringent requirements for diagnostic assay development and manufacturing. The reliable, large-scale, manufacturing capacity with lot-to-lot traceability, choice of defined capillary speeds to select sensitivity of diagnostic test and straight and uniform migration front make Vivid nitrocellulose membranes a popular choice with diagnostic assay developers.
