Gel: Fusarium graminearum strain 453 reference map (html display)

Name: Fusarium graminearum strain 453 reference map

Description: Proteome reference map of the nivalenol producer strain Fusarium graminearum 453 using a 2D-DiGE protocol. In order to obtain a more complete map, the Fusarium graminearum 453 strain was grown in two different culture media, one containing Glutamic acid as source of Nitrogen and the other containing Agmatin as Nitrogen source. Both media are considered to be good inducer of toxin production.

1) Turn on the Typhoon and leave the instrument to
warm up for at least 30 min prior to scanning.
2) Ensure that the gel glass plates are clean, dry and free from lint.
3)Select scan area
4)Select the appropriate wavelenths and adjust the intensity of the lasers in a way to have the maximum signal with no saturation. The adjustemnt can be done using a scanning resolution of 1mm
5)After calibration scan the gel setting the resolution to 100 um.
