Whatman Membrane Filters

Whatman Membrane Filters

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 (80100g/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 (0.2m) is recommended for protein samples below 20kD and the Protran BA-85 membrane (0.45m) 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.
