The Elutrap system is designed to isolate nucleic acids and proteins from agarose or polyacrylamide gel slices by electroelution. Samples are purified with . azim58 – Official elutrap documentation. Elutrap protocol. “C:\kurt\storage\CIM Research Folder\DR\\\ELUTRAP\ “. The Elutrap, seen from above, is placed on a horizontal agarose gel electrophoresis chamber. Outer limits of the trap are defined with disposable membranes at.

Take care not to crush the gel as this may impair elution efficiency. If for any reason eluyrap decide that your purchase just isn’t for you, simply return the item within 30 days of receipt and we’ll cover the cost of return shipping.

Whatman Elutrap Electroelution System, Whatman 10404090 Replacement Components BT1 Membranes

Prices shown may not reflect the correct price. Collecting the sample too slowly can result in collection of a greater volume of the buffer as the buffer continues to diffuse into the collection chamber. Do not crowd the gel pieces on either end of the elution chamber. If possible, please enable JavaScript in your browser for the best possible experience. Replacement electrophoresis chamber for the Elutrap Electroelution system. Elutrap electro-elution system is a membrane trap elution system used for the extraction, concentration and eltrap of DNA and other charged molecules above the size of 5 kDa 1.


Remember to cut the dialysis membrane with one edge slightly higher than the other similar to the shape of the BT1 membrane. Ultrapure TBE buffer — about 15 ml mnual device used.

We however use a single layer in the device. Place the elutrap device into one of the channels of the tray insert of the electrophoresis chamber.

Maanual Elutrap system is designed to isolate nucleic acids and proteins from agarose or polyacrylamide gel slices by electroelution. It is essential to then autoclave the buffer to remove all traces of DEPC.

Elutrap Electrophoresis Chamber

Wlutrap it between the screw and the closed U insert in the smaller chamber of the elutrap device. Do not stack gel slices above the device height.

A small beaker containing DI water — to place dialysis membrane prior to use. When I first started doing some research about the equipment, I found that Schleicher-schuell the company which initially came up with the elutrap elutral acquired by Whatman, and the protocol was no longer published online.

However, take precautions to keep the BT2 membrane dry for as long as possible. This is another protocol that I wrote for Dr Kim’s Lab, which proved to be very useful.

Why Buy From Us? The membranes should only be handled with gloves on to avoid RNase contamination. The Elutrap system can also be used for concentration of dilute solutions.


For more brand name Laboratory Apparatus please visit our Laboratory Apparatus store section. Please add ” labplanet.

The buffer in the elution chamber should be about one mm from the top. I have a saved copy of the old protocol, and if anyone mwnual it, eltrap free to get in touch with me. Separates DNA, proteins, and nucleic acids from gels and gel slices without salt cushions, special buffers, or pretreated membranes.

Elutrap Electrophoresis Chamber Replacement electrophoresis chamber for the Elutrap Electroelution system.

Info for a Biotech Student: Elutrap electro-elution system

We apologize for any inconvenience. The size of slutrap collection chamber formed by the dialysis membrane and the BT2 membrane can be varied by altering the position of the placement of the latter membrane. The notched surface of the inserts always faces the central elution chamber containing the gel pieces. Be the first to leave a review! To check for the proper placement of the two membranes, place the device upright with the dialysis membrane on top, add some DI water and check for signs of leakage.

If you suspect contamination of the equipment with RNase, wash with 0.
