How to avoid contaminations and why

 

Keratins are omni-present and notorious contaminating proteins originating from skin, hair, dust, clothes, chemicals, etc. Total elimination is virtually impossible (and not necessary), but over-abundance will result in the repeated identification of keratins, and not your protein of interest.

Therefore, a clean lab environment will certainly benefit the outcome of the MS experiment.

  • Wash all surfaces, tools and containers with MQ and 70% ethanol
  • Work always with dowder-free nitrile gloves
  • Make fress buffres and use disposable plastic tubes/falcons for buffers or use HPLC grade water or MQ washed bottles 
  • Using lab coats prior to peptide digestion is recommended
  • We recommed to use commertial SDS-PAGE gels
