Availability: DNA and RNA
Location: 5′ and 3′ Scale: 1 umol to mid-scale
Purification: HPLC required; PAGE is not recommended as it can impair enzyme activity
IDT ordering symbol: This is a Non-Catalog modification. Please contact email@example.com with your sequence design for review and quoting.
Horseradish Peroxidase, or HRP, is an enzymatically active glycoprotein that can be conjugated to an oligonucleotide via a maleimide attachment to form a thioester. In the presence of H2O2, this enzyme catalyzes an oxidation reaction that converts reduced, non-fluorescent or non-colorimetric substrates into oxidized, fluorescent or colorimetric forms .
Research shows that HRP directly conjugated to hybridization probes can increase signal amplification in Catalyzed Reporter Deposition-Fluorescent In Situ Hybridization (CARD-FISH) protocols . This modification can also be used in nonradioactive immunoassays, northern/Southern blot analysis, and other in situ hybridization applications.
How to submit a request for HRP-oligos
Synthesis of HRP-modified oligos requires special chemistry; therefore these sequence designs must undergo review and quoting prior to synthesis. IDT scientific experts meet regularly to review the complexity and feasibility of producing nonstandard sequence requests including oligos containing HRP modifications.
Please direct inquiries to firstname.lastname@example.org with your contact information and requested sequence, including any additional modifications or yield requirements.
