6 Image Lab Software for Obtaining Stain-Free Gel and Blot Images

Obtaining Stain-Free Blot Images

Instructions

1. Once the blotting step is complete, remove the blot and place it directly on a stain-free enabled

Bio-Rad UV transilluminator plate (ChemiDoc MP, ChemiDoc XRS+, Gel Doc XR+) or stain-free tray
(Gel Doc EZ).

Note: No fixation or rinsing steps are required. Membranes are more transparent to UV illumination when
wet. For optimal imaging, keep membranes wet with transfer buffer or water. Transfer buffer or water
also helps minimize air bubbles that can be trapped under the membrane.
Note: Do not place any material, such as plastic film, between the blot and the plate or tray.

2. Open Image Lab software.

a. Version 4.1 or later for Gel Doc EZ or ChemiDoc MP.

b. Version 5.1 or later for Gel Doc XR+ or ChemiDoc XRS+.

Download Image Lab version 5.1 at www.bio-rad.com/imagelabsoftware.

b. Select
