The RNA CS (RCS) is the RNA Calibration Strand is the Enolase II from YHR174W. The transcript is 1,314 nucleotides long and also includes an additional 30-nucleotide poly(A) tail. The reference fasta file for the YHR174W ENO2 mRNA is available for download here.

• RCS is included in the Direct RNA Sequencing kit (SQK-RNA004)
• The RNA Control Expansion (EXP-RCS001) includes three tubes of RCS

The concentration of the RCS vials was increased from 15 ng/µl (RNA004.20.0001 or older and RCS001.10.0004 or older) to 50 ng/µl (RNA004.30.001 or newer and RCS001.20.0001 or newer)
