Line or dot immuno strips are still widely used in IVD tests. Many infectious diseases generate indeed a complex immune response and necessitate checking the patient serum for the presence of several antibodies. Today, the self wetting nitrocellulose membrane is still the best uniform substrate for the binding of these different immuno-dominant antigen proteins. The UniSart® 0.22 μm and 0.45 μm nitrocellulose membranes have been designed to show exceptional consistency in IVD immuno strips.
UniSart® nitrocellulose membranes have been designed to be the ideal solid phase for Lateral Flow, able to bind high amount of capture reagent and yield a controlled and fast wicking of samples. Developed in the mid–80 for pregnancy testing, more than a billion Lateral Flow Immunoassays are today produced per year. Many markers such as cardiac, cancer, drug abuse and more can be analysed on such a strip. Like an ELISA it uses the powerful antibody/antigen reaction but in a one-step format.
