The nylon or glass substrate on which the probe solution is deposited must be pretreated with coupling agents such as lysine or acrylamide functional groups. Coupling agents bind the probe cDNA to the substrate. After hybridization, the array is washed in heated isopropanol and water to remove any unhybridized sample DNA. It is essential... [Pg.336]

On the other hand, new combined coupling agent — corrosion inhibitor pretreatment processes 29 125 have provided a new approach to increasing metal/epoxy adhesion systems with limits that are not yet known. [Pg.53]

Commercially produced nylon 66 core fibers were washed with water to remove the spin finish and then pretreated with two different coupling agents l,4-bis(3-aminopropyldimethylsilyij-benzene (APDMSB) obtained from Petrarch, and fumaric acid (FA) ... [Pg.532]

Adhesion promoters. Sometimes referred to as coupling agents, these additives have the ability to enhance resin adhesion to surfaces such as glass or metals(8). The most popular type are silanes which can either be mixed with the adhesive itself or applied to the substrate as a primer. They will be further considered in Chapter 3 under adhesion and surface pretreatment. [Pg.42]

The possibility of avoiding the need for complex pretreatments by promoting chemical bonding with coupling agents. [Pg.106]

An enormous literature is devoted to surface pretreatments for durable bonding, as discussed in Chapter 3. Suffice it to say that chemical etching, surface conversion coatings, coupling agents and primers all have a place among the techniques. It would seem that... [Pg.171]
