Product Details
HS code: 39207990
EAN: 8721028169174
Brand: Cytiva
Material: nitrocellulose (100 %).

Transfer membrane for most nucleic acid and protein immobilising techniques

Replaces Protran® BA 85 from Whatman®

Multiple use - ideal for most nucleic acid and protein immobilising techniques. Pure nitro-cellulose, free from cellulose acetate and triton. They have a high binding capacity and low background.


Directions for use

Nitrocellulose should only conditionally be used for electrophoretic transfer of nucleic acids, because of the high salt concentrations required for the transfer.
Membranes of 0,45 μm pore size allow for DNA transfer (minimum 300 bp) and protein transfer (minimum 20 kDa).


Application examples

Southern, Northern, Western transfer, colony and plaque hybridisation, immunoblots, nucleic acid and protein dot-blot, slot-blot, electrophoretic transfer of proteins.
Detection systems are radioactivity, chemoluminescence, colour



Transfer membrane Amersham™ Protran® NC 0.45 roll 400 × 20 cm

In practical roll format for maximum flexibility in cutting.
