qPCR primer und probes for your COVID-19 research:
We produce primers and probes for SARS-CoV2 qPCR assays as recommended by WHO. These oligos are available with all established dye/quencher combinations and also as large scale syntheses. Please contact our customer support team for futher information.
Primer/probe-mixes for the detection of SARS-CoV2 variants now offers QIAGEN™-developed LNA-based qPCR genotyping assays for use with the QIAprep& Viral RNA UM Kit to track the current SARS-CoV-2 variants of concern.
Modifications for enzymatic coupling of oligonucleotides to proteins

Benzylguanine und Benzylcytosine

Triglycin (Gly-Gly-Gly) for sortase-mediated linking reaction
5'-Hydrazide Modification: Reactive Linker
An efficient way to link oligos to other biomolecules is the hydrazide-aldehyde coupling.
Aldehydes represent highly reactive carbonyl compounds that can react with hydrazides under neutral or slightly acidic conditions to form stable hydrazone conjugates in a fast and efficient way. Thus, a conjugation of oligonucleotides to other (bio)molecules can be achieved easily under physiological conditions.
