Establishing Standards for Scientific Research

ATCC develops standards for the biomaterials community

ATCC develops national consensus standards for biomaterials and related processes. In 2007, we became the first biological resource organization to be accredited by American National Standards Institute (ANSI) as a Standards Development Organization (SDO). ANSI accreditation ensures that procedures used by standards developers meet the requirements for openness, balance, consensus, and due process and that the voluntary consensus standards produced are compatible with the requirements of the International Organization for Standardization (ISO).

ATCC published the following consensus standards:

  • Standardization of In Vitro Assays to Determine Anthrax Toxin Activities (ASN-0001)
    • PDF (available on ANSI)
  • Authentication of Human Cell Lines: Standardization of Short Tandem Repeat (STR) Profiling (ASN-0002)
  • Species-Level Identification of Animal Cells through Mitochondrial Cytochrome C Oxidase Subunit 1 (CO1) DNA Barcodes (ASN-0003)
    • PDF (available on ANSI)
