HUMAN PROTEINPEDIA 


Experimental Details - HuPA_00696
Experiment type Mass spectrometry
Short description SILAC-based quantitative proteomic analysis of gastric cancer secretome
Experimental description We used a SILAC-based quantitative approach coupled with tandem mass spectrometry to identify differentially expressed proteins Proteins enriched in the cell supernatants were resolved by in-gel and SCX-based fractionation methods. The resulting mass spectral data was searched against the NCBI RefSeq49 human protein database using two different search algorithms Mascot and SEQUEST
