A wide range of phosphoramidites and supports is available for research in the design of non-fluorescent probes.
Glen Research offers products for the generation of probes for electrochemical detection.
Several phosphoramidites and supports are available that can be useful in the study of enhanced cellular uptake and membrane permeation.
Haptens are small molecules for which antibodies have been developed. Examples of haptens that are used extensively in oligonucleotide synthesis are biotin, fluorescein and the 2,4-dinitrophenyl group.
