| Whatman Protran Nitrocellulose Membrane Filters, Whatman Filters | |||||
| Ideal for Western and Southern blotting techniques, protein transfers, colony and plaque lifts. White membranes are made of 100% nitrocellulose (no added cellulose acetate) for high binding capacity (80–100µg/cm2). Less than 1.0% extractables for cell growth and tissue culture applications. Quality controlled. To sterilize, membranes can be autoclaved (liquid cool cycle) or irradiated. The Protran BA-83 membrane (0.2µm) is recommended for protein samples below 20kD and the Protran BA-85 membrane (0.45µm) is recommended for general nucleic acid work. | |||||

| Whatman Nytran SuPerCharge and Nylon Membranes, Whatman Filters | ||||
| Nytran SuPerCharge membranes have a very high positive charge and feature greater density of nylon. They bind three times more negatively-charged dye than typical positively-charged nylon membranes. Membranes boast uniform pore size and distribution. This consistent morphology leads to greater reproducibility of results across a membrane and from blot to blot. Membranes deliver a high signal with extremely low background when used with radioactive or non-radioactive detection techniques. Nytran nylon membranes are ideal for applications that require a lower charge. These membranes are designed for Southern and Northern blotting, colony and plaque lifts, and dot- or slot-blots. Membranes are cast uniformly for excellent symmetry and to prevent curling. Butterfly membrane has asymmetric notches and tabs for easier handling, improved orientation, and identification of colony and plaque lifts. | ||||
