ERCC-00095*
Methanocaldococcus jannaschii
• Designed to challenge nucleic-acid
based detection technologies
• Target DNA sequence inserted via
homologous recombination
- Conveys specificity
- Eliminates false positives from
near-neighbors
- Sequencing confirms one copy
per genome
• Lyophilized format
* External RNA Controls Consortium (ERCC)
- NIST Standard Reference Material (SRM) 2374: DNA Sequence Library for External RNA
Controls
- ERCC-00095 corresponds to the latter three (of eight) open reading frames in the phosphate
specific transport complex component of
M. jannaschii
