Cell Authentication Testing Service

Submit STR Service Request

ATCC has partnered with industry-leader Promega® to offer a complete cell line authentication service utilizing Short Tandem Repeat (STR) profiling. STR profiling aids in the detection of misidentified, cross-contaminated, or genetically drifted cells, which invalidate research results. STR profiling is a rapid, reproducible, and standardized PCR-based method for the authentication of human cell lines. ATCC’s STR report meets requirements for funding, publication, and quality control.


    • ATCC trained experts amplify 17 STR loci plus Amelogenin using Promega’s PowerPlex® 18D System.
    • A comprehensive analysis interprets both karyotypically normal and abnormal cell lines.
    • A no-fuss sample mailer packet is provided with which cells are spotted onto paper and mailed to ATCC using the pre-addressed envelope.

3 Easy Steps

    1. Place an order by clicking the “submit” button
