Choose the function
Start with the role the modification must perform in the experiment.
Functional construct
Labels, quenchers, linkers, and other groups define oligonucleotide functionality. Review purpose, position, and compatibility before selection.
Start with the role the modification must perform in the experiment.
Not every group is available at 5′, 3′, and internal positions.
The price depends on the selected modification and synthesis scale.
Functional groups
Position, incorporation route, purification, and sequence notation matter as much as the group name. The catalog below provides actual symbols and allowed positions.
Common for labels, phosphate, linkers, and protective groups.
May carry a label, quencher, extension blocker, or support-linked group.
Usually requires a modified residue or linker.
At least 95% purity is stated for purified fluorescent constructs.
Major classes
Modification classes change optical, chemical, or biological properties.
Provide detection and may be terminal or internal when supported by the chemistry.
Suppress fluorophore emission in probes; the working range must overlap dye emission.
Supports high-affinity avidin or streptavidin binding for immobilization and detection.
Provide a reactive group for post-synthetic conjugation.
Create distance or replace an unspecified sequence region.
Increase nuclease resistance for protected constructs.
Fluorescent labels
A dye may be incorporated during synthesis, through modified CPG, or post-synthetically through an amino linker.
Introduces the label during solid-phase synthesis at an allowed position.
Used for selected 3′ terminal dyes.
An activated dye reacts with an amino linker and requires additional purification.
Often requires a modified dT linker and a dedicated sequence symbol.
Purification and control
Fluorescent constructs use multi-stage separation followed by optical and size confirmation.
Gel filtration removes free dye and salts.
HPLC or PAGE removes unreacted oligonucleotide.
The spectrum confirms dye and nucleotide contributions.
May be used for selected fluorescein-labeled products.
Practical questions
The public name describes the chemistry, while the technical symbol encodes position and sequence notation.
No. Allowed 5′, 3′, and internal positions depend on the exact chemistry.
They require a modified residue or linker and may add synthesis and purification steps.
Выберите группу, найдите модификацию по символу или названию и сравните ориентировочную стоимость для доступных фасовок.
Модификация важна не только сама по себе, но и тем, где она может стоять в последовательности. Перед заказом проверьте расположение, спектральные параметры и совместимость с очисткой.
Чаще используется для флуорофоров, биотина, фосфатных и других терминальных меток.
Обычно подходит для гасителей, блокирующих групп и терминальных модификаций зонда.
Подходит для dT/dC-модификаций и конструкций, где метка должна быть внутри цепи.
Для зондов сравнивайте λem красителя с диапазоном гашения, а не только названия.
