WebDescription. Novex™ TBE Gels 6% provide high-resolution analysis of restriction digests and PCR products. Designed to run on the XCell SureLock™ Mini-Cell, the polyacrylamide gels give sharp, clearly resolved, intense bands, and provide separations of double-strand DNA fragments from 65–250 bp. WebSolvents can also affect the selectivity of a reaction. For example, in the reaction between two or more isomers, the choice of solvent can selectively dissolve one isomer, leading to the formation of a specific product. Intermediates: An intermediate is a short-lived species formed during a chemical reaction.
