Strategies for Attaching Oligonucleotides to Solid Support

چکیده
Many important molecular applications, such as DNA oligonucleotide arrays, utilize synthetic oligonucleotides attached to solid supports. The most accessible approach for producing an oligonucleotide microarray is to synthesize individual oligonucleotides and subsequently immobilize them to a solid surface. For this immobilization to take place, the oligonucleotides must be modified with a functional group in order to have attachment to a reactive group on a solid surface.

Strategies for Attaching Oligonucleotides to Solid Supports
While most molecular reactions involving synthetic oligonucleotides, notably PCR and DNA sequencing, are carried out in liquid phase, a rapidly growing number of important applications utilize synthetic oligonucleotides attached to solid supports. In general, the purpose for using a solid support-attached oligonucleotide is to capture something, hold on to it, enrich it, and identify and/or pur...
متن کاملSolid phase DNA amplification: characterisation of primer attachment and amplification mechanisms.
Different chemical methods used to attach oligonucleotides by their 5'-end on a glass surface were tested in the framework of solid phase PCR where surface-bound instead of freely-diffusing primers are used to amplify DNA. Each method was first evaluated for its capacity to provide a high surface coverage of oligonucleotides essentially attached via a 5'-specific linkage that satisfyingly withs...
متن کاملSynthesis of oligonucleotides on a soluble support
Oligonucleotides are usually prepared in lab scale on a solid support with the aid of a fully automated synthesizer. Scaling up of the equipment has allowed industrial synthesis up to kilogram scale. In spite of this, solution-phase synthesis has received continuous interest, on one hand as a technique that could enable synthesis of even larger amounts and, on the other hand, as a gram scale la...
متن کاملPorous silicon-based nanostructured microparticles as degradable supports for solid-phase synthesis and release of oligonucleotides
We describe the preparation of several types of porous silicon (pSi) microparticles as supports for the solid-phase synthesis of oligonucleotides. The first of these supports facilitates oligonucleotide release from the nanostructured support during the oligonucleotide deprotection step, while the second type of support is able to withstand the cleavage and deprotection of the oligonucleotides ...
