CellMosaic® has designed this PerKit™ HRP−Oligo conjugation kit to prepare single-labeled HRP−oligo conjugates with linkers and conjugation chemistry that retains the activity of HRP. The same configuration and chemistry have been tested for HRP-oligos with different oligo sequences at a few diagnostic companies since 2011.
The kit is designed to work with amine-modified oligos. The user supplies the amine-modified oligos, which are readily available from many commercial oligo suppliers. Using the kit components, the user converts the amine-oligo to a thiol-oligo, followed by reaction of the thiol-oligo with activated HRP to generate the HRP-oligo conjugates. The total length of the linkage between the HRP and the amine-oligo is 29 atoms excluding the linker used for amine modification of the oligo. The Q-column purification step typically provides the resulting HRP-oligo at greater than 80% purity.
This kit is an upgraded and improved replacement kit with slightly different components and workflow as the first-generation kit (Cat# CM53401). This kit has multiple configurations for various lengths of oligos and can be used to conjugate between 1 to 5 nano-mole (nmol) of oligo. Table 1 provides the catalog numbers for various kit configurations and Table 2 lists the kit components.

Key Features of this HRP-Oligo Conjugation Kit:
-
High quality maleimide-activated HRP for the conjugation: >99% purity and >200 units/mg protein activity.
-
A single purification step affords 85~90% of single labeled HRP-oligo conjugates if the quality of the oligo is at par.
-
Preparation can be done in a day.
-
Stable linkage with optimal spacer to make sure there is no interference between oligo binding and HRP activation.
-
All reagents included, from preparation to purification.
- Options to choose tailored services at CellMosaic after conjugation:
- You can choose to send your conjugates to CellMosaic for HPLC analysis of the sample or complete removal of trace oligo impurities and unreacted HRP.
