Tau protein is an integral component of paired helical filaments, a pathological feature of Alzheimer's disease. tau extracted from these filaments displays decreased electrophoretic mobility due to aberrant phosphorylation. Here we show that recombinant human tau can be phosphorylated by cAMP-dependent protein kinase resulting in decreased electrophoretic(More)
Biotin has been converted to 2-(biotinylamido)ethanol and condensed to phosphorylated oligonucleotides in a solid phase synthesis. The 5'-biotinylated oligonucleotides were enzymatically coupled to other DNA fragments by T4 DNA ligase or T4 RNA ligase. The hybridization properties of such biotin-labeled oligonucleotide probes were studied.
