Whatman Nytran nylon membranes are suitable for applications that require a lower charge. They are designed for Southern and Northern blotting as well as colony and plaque lifts and dot-/slot-blots. Nytran N is compatible with isotopic and nonisotopic detection methods.

Nytran N membrane allows for excellent signal-to-noise ratios. The membrane is cast uniformly on both sides of a support matrix, demonstrating excellent symmetry. This gives the membrane the ability to lie flat without curling. Nytran N membrane is a highly consistent membrane with uniform pore size and distribution. It is available in 0.2 µm and 0.45 µm pore sizes for optimal retention of oligos and larger DNA fragments.
