Introduction The main focus in proteomic studies is on the identification of proteins in given biological samples. Proteins isolated and separated from a given sample (e.g., whole cell lysates, blood or tissue, protein complexes) by immunoprecipitation or affinity chromatography or ...

Introduction Transfection of cells is one of the main techniques used to influence gene expression. Most primary cells and human skeletal myoblasts (SkMC) in particular are very difficult to transfect, whereas for cell lines such as C2C12, many suitable transfection reagents and protocols are ...

IntroductionSeveral scientific studies support the claim that natural scrapie is associated with polymorphisms at three codons within the sheep prion protein (PrP) gene. Genotyping of these codons (codon 136 [alanine, valine], 154 [arginine, histidine], and 171 [glutamine, arginine, ...

MicroRNAs (miRNAs) are naturally occurring, highly conserved families of transcripts (18–25 nt in length) that are processed from larger hairpin precursors. Both plant and animal genomes encode miRNAs, and to date, there are over 4000 mature miRNA transcripts annotated. Although miRNAs ...
