Large Cellophane

The Large Cellophane (Cat. No. NC2200) is a component of the Large Gel Drying Kit (Cat. No. NI2207). The Cellophane Dimensions are 22.35 cm × 22.85 cm. You will find these dimensions in the manual of the Drying Kit on page 4 (see link: https://assets.thermofisher.com/TFS-Assets/LSG/manuals/geldrying_man.pdf).

Please see below for possible causes and solutions:

- Air trapped between cellophane layers. Apply adequate Gel-Drying solution to prevent bubbles between the gel and cellophane assembly.
- Tension on cellophane too strong. Take care not to stretch the cellophane during dryer assembly.
- Rough edges or small cracks on gel edges. Trim rough edges from the gel to eliminate starting points for cracks.
- Cellophane slips during drying. Make sure clamps hold all four edges of the dryer assembly firmly.

Usually it is not necessary to peel off the cellophane. If your signal is very faint and you are concerned about getting an exposure, you can rub the top surface of your gel with a damp towel and then peel off the cellophane. Then air dry the gel for a few minutes and perform autoradiography.

Gels turn white when they are dried too rapidly, usually in an environment that is too ventilated, drafty, or warm. You can remedy this problem by dabbing the gel with deionized water on a Kimwipe tissue to rehydrate the white areas. Re-dry the gel in a dark, dry, non-drafty place, such as a drawer or cabinet.
