The Whatman Nytran® N membrane is ideal for applications that require a lower charge. It is designed for Southern and Northern blotting as well as colony and plaque lifts as well as Dot/Slot blots. Nytran® N is compatible with isotopic and non-isotopic 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 0.2µm and 0.45µm pore sizes for optimal retention of oligos and larger DNA fragments.
