FIG. 1.

SDS-polyacrylamide gel of protein standards (left lane; molecular masses [in kilodaltons] are on the left) and the bacteriocin albusin B (right lane), following its elution from the BioGel P6 column (Table 1). The image was obtained by scanning the dried gel directly with an Envisions flatbed scanner into Adobe Photoshop 7.0 (operating on Macintosh OS9.0) and converting the colored image to grayscale prior to saving it as a TIFF image.
