"duplicate products" is a correct and usable phrase in written English.
You can use it when you are referring to items that are exact copies of each other. For example, "The store offered a wide selection of duplicate products for customers interested in saving money."
It certainly has not been significant enough to have confounded the phylogenetic inference presented by Laukaitis et al. (2008), and we feel that it should not adversely affect our analysis of recently duplicated products presented here.
Sequence alterations were confirmed by sequencing duplicate PCR products and/or by digesting PCR products with the specific restriction endonuclease whose recognition site had been concomitantly altered.
The second avenue of forming interactions between duplicate gene products involves a non-homodimerizing protein that undergoes duplication.
Byun-McKay and Geeta [ 52] have proposed that subcellular relocalization of duplicate gene products may play an important role in stabilizing duplications and acquiring new functions.
The duplicate PCR products were pooled, the DNA concentrations were normalized and the samples were purified using the Agencourt AMPure system (Beckman Coulter).
For sequencing based ASE, duplicate PCR products were mixed and gel purified, sequenced using BigDye Terminator chemistry (Applied Biosystems) and resolved using an Applied Biosystems 3730XL DNA analyzer.
Duplicate PCR products were pooled and purified with the QIAquick PCR Purification Kit (QIAGEN, UK) and stored at -20°C.
A randomly selected panel of 20 paired WB4 and WB20 duplicate amplification products were sequenced and coreceptor tropism was inferred by geno2pheno [coreceptor].
As described earlier [ 22], one can use the observed number of physical interactions among duplicate gene products (cross-interactions) to estimate attachment rates.
