Abstract: The present invention relates to a target retainer device for adhering a target to a substrate for a variety of target and substrate types. The target retainer includes an impact-hold-resistant shaft to ensure the target remains in place during impact over multiple uses but can be easily inserted and removed from a substrate or a substrate covering or exterior to allow for reuse. The target retainer is available in multiple lengths for the best performance and ease of use based on substrates or substrate coverings or exteriors.

Abstract: The invention provides an internal control nucleic acid molecule including at least one forward primer binding site, at least one reverse primer binding site, and at least one amplifiable region, wherein the forward primer binding site, the reverse primer binding site, and the amplifiable region are all randomly generated. The invention also provides a kit that includes at least one internal control nucleic acid molecule of the invention, at least one forward primer, configured to be complementary to the forward primer binding site of the internal control nucleic acid molecule, and at least one reverse primer, configured to be complementary to the reverse primer binding site of the internal control nucleic acid molecule. The invention also provides methods of using the internal control nucleic acid molecules and kits of the invention.

Abstract: A method is provided for reverse transcription-polymerase chain reaction (RT-PCR) comprising a) amplifying a reverse transcribed cDNA in a mixture comprising Norovirus Genogroup I and Norovirus Genogroup II primers and probes, wherein said Norovirus primers and probes distinguish between Genogroup I and Genogroup II viruses; b) quantifying virus; and c) normalizing data based on a universal internal RNA control. Optionally, the method may also include primers and probes for Enteroviruses. A reaction mixture comprising Norovirus Genogroup I and Norovirus Genogroup II primers and probes, wherein said Norovirus primers and probes distinguish between Genogroup I and Genogroup II viruses and universal internal RNA control primers and probes are also included.
