Solid Phase Synthesis of a Fluorescent Peptide: Comparison of Fmoc-Lys(5-FAM)-Resin and Fmoc-Lys[5-FAM(Trt)-Resin
Poster Apr 13, 2007
We have prepared and performed comparison studies using two kinds of resins, Fmoc-Lys(5-FAM)-Rink Amide resin (I) and Fmoc-Lys[5-FAM(trt)]-Rink Amide resin (II), the latter contains a phenolic hydroxyl group protected with a trityl group. Syntheses were carried out under the same standard conditions and the peptides obtained showed no significant difference in purity. The results of these studies showed that resin (I) is adequate for synthesis of C-terminal fluorescent labeled peptide.
When there is a need to quickly analyze samples using a number of different PCR assays, it is likely that optimal conditions for each assay will not be the same. First, different assays often will require different annealing temperatures for their primers. In addition, amplicons may be designed to be of different lengths and therefore require varying durations of the extension step.READ MORE
