These CRMs have been prepared according to ISO Guides 30-35 and are intended to serve as control material for third party testing of cotton for transformation events and for no other purpose. The purity of the conventional and Liberty Link® cotton was verified using DNA- based detection methods. AOCS 0306-A and AOCS 0306-E are available in sterile, 0.5ml skirted screw-cap self-sealing tubes. Bayer CropScience, Gent, Belgium provided the conventional Cotton DNA and the transgenic Cotton DNA which were extracted from clean leaves. The sample shall be stored in the self-sealing tube at +4 C in the dark.

AOCS Technical Services is offering the CRMs for U.S. $175 each plus shipping & insurance.
