The HeLa Protein Digest Standard is a highly validated mammalian protein digest that may be used as a quality control sample for mass spectrometry (MS) analysis of complex proteomic samples.

• Complex mammalian proteome sample protein digest (>15,000 proteins) from the HeLa S3 cell line
• Prepared using both LysC and trypsin to ensure less than 10% tryptic missed cleavages
• Validated peptide quality with <10% methionine oxidation and <10% lysine carbamylation
• High-quality, consistent protein digestion backed up by rigorous testing and documentation
• Provided in a stable lyophilised format
