Whatman Nytran nylon membranes are available in two formats: Nytran N is moderately charged and Nytran SuPerCharge (SPC) has a very high positive charge.

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 0.2µm and 0.45µm pore sizes for optimal retention of oligos and larger DNA fragments.

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.
