A range of unbacked nitrocellulose membranes for use in a lateral flow assay.

•     AE membranes are unbacked, allowing either belt or air side of the membrane to be used.
•     Enables assay suitability tests of both air and belt side of the membrane.
•     Constructed of 100% nitrocellulose.

AE Membranes

Constructed of 100% nitrocellulose, the AE family of membranes offers a higher level of purity and performance compared to post-treated materials. The AE membranes have been used extensively since the development of the original lateral-flow tests and have become a standard for manufacturers worldwide. There is a long history of success and experience for the optimization of these products in assays. AE membranes are unsupported, which means either the belt or air side of the membrane can be used.

Nitrocellulose Membranes

Nitrocellulose membranes are a key functional part of lateral-flow assays. The membrane must provide sufficient protein binding to enable the formation of a sharp and intense capture line, but at the same time the level of nonspecific background must be low for easy interpretation of results. Nitrocellulose membranes are available in a range of wicking rates and formulations. It has long been known that the wicking rate of a membrane has a significant impact on test sensitivity.
