Thermo Fisher Scientific Quantu<u>mRNA</u> Classic II 18S Internal Standard

Invitrogen™ QuantumRNA™ Classic II 18S Internal Standard

The Ambion™ QuantumRNA™ 18S Internal Standard with Competimer™ technology uses specially modified Competimers of the same sequence as the normal 18S primers that cannot be extended. By adjusting the ratio of 18S Competimers to normal 18S mRNA primers, the signal for 18S mRNA can be attenuated to the level of very rare messages.

They are used for quantitative end-point RT-PCR and include sufficient reagents for 100 reactions. Because of its invariant expression across tissues and treatments, 18S ribosomal RNA is an ideal internal control for quantitative RNA analysis. The Classic II 18S Internal Standards produce a 324 bp PCR product.
