San Francisco, CA – Dr. Chi Yang, the CEO of SynPep, a provider of custom peptide synthesis and antibody research products, was indicted by a federal grand jury on 13 counts of mail fraud and false statements for falsifying the purity levels of the company’s peptide products. The indictment claims that under Dr. Yang’s supervision, employees falsified chromatograms showing peptide purity and misidentified products. SynPep supplied peptides to private and public research institutions, including the federal government. “SynPep allegedly falsified graphs that were used in support of cancer or AIDS research, and that research may now be called into question,” stated Kevin V. Ryan, US Attorney for Northern California. The indictment is the result of a two-year investigation involving federal, state and Alameda County agencies.
