Sample preparation guidelines

Samples for in-gel digests:
1. Coomassie stained gel bands from 0.75 to 1.0mm SDS-PAGE gels can be submitted in centrifuge tubes without water. Please label sample names on tubes.
2. In general, for protein ID from gel bands, any band clearly visible by Coomassie staining is acceptable.
3. To minimize keratin contamination, please use freshly prepared reagents, buffers, and work in a laminar flow hood when preparing samples.
4. Please de-stain gels thoroughly.
5. Please do not combine different bands in the same tube.
6. We DO NOT ACCEPT silver staining gel bands.
  
Samples for in-solution digests:
1. Proteins should be desalted in a water-based buffer with either dialysis or centrifuge filter in an appropriate MW cut-off membrane.
2. Please submit 40μl of 10μM of protein sample in centrifuge tubes with clear labeling on top/side.
3. If your sample has detergents and surfactants, they will have to be run on SDS-PAGE.  Submit gel bands for analysis.
  
Protein digestion:
1. The enzyme used for digestion is trypsin. If you want a digestion with another enzyme, you will have to provide it.
