Protein gel electrophoresis
We perform gel electrophoretic experiments in 1 und 2 dimensions according to established protocols or your settings (1/2-PAGE). To that end, both Bio-Rad, Amersham and Gelcompany/Serva devices are available.
We have also several years of experience with the DIGE-system for differential protein expression analysis.
Necessary protein amounts:
- 0.5-1 mg for Coomassie staining
- 0.15 mg for analytical DIGE gels (0.075 mg each for control and sample)
- 0.5 mg for preparative DIGE gels
Limits of detection:
- Coomassie R250 30-100 ng
- colloidal Coomassie G250 1-16 ng
- silver 1-10 ng
- fluorescence 0.1-5 ng
Typhoon 9400 is a high-performance fluorescence scanner with 3 lasers (457/488, 532, 633 nm) for various applications such as the detection of phosphoproteins using Diamond Pro Q stain.
