Transfer Membranes Manufactured, Tested, and Stocked by GE Osmonics

Date presented: 02 May 1997

Unlike many transfer membrane suppliers, GE Osmonics manufactures all of its nitrocellulose, PVDF, and nylon membranes that we sell. Our transfer membranes are used in key research and testing done around the world.

Nylon

GE Osmonics manufactures a complete line of nylon membranes to match all of your applications. Magna nylon offers higher binding capacity than nitrocellulose membranes and works well in a wide variety of applications. MagnaProbe is specifically designed to offer a higher number of reprobings than other membranes. Nylon membranes are also available as notched and gridded discs for use in Colony/Plaque lifts.

PVDF

The PVDF-Plus is a naturally hydrophobic transfer membrane designed to deliver the highest binding capacity and lowest background in protein analysis applications.

Nitrocellulose

GE Osmonics manufactures two pure nitrocellulose transfer membranes. NitroBind is the classic unsupported pure nitrocellulose membrane used for all protein and immunoblotting applications. NitroPure is a supported pure nitrocellulose membrane combining the characteristics of nitrocellulose with the strength of nylon. It outperforms standard nitrocellulose in reprobing applications of DNA/RNA/Protein when extensive handling is required. Most other suppliers buy membranes from a manufacturer and sell them under their label. The chart below shows which of the market leaders actually make the transfer membranes they sell.
