Cellulose phosphate is used in protein chromatography, ion exchange chromatography and cation exchange media. Cellulose phosphate (CELLPHOS) has been studied as a collector for analytical preconcentration of traces of Cd(II), Cr(III), Cu(II) and Ni(II) from aqueous sample solution and used to purify and characterize acid phosphatase from approximately 3000-year-old human bones from archeological excavations.

Plasmid DNA replication in nuclear extracts of Saccharomyces cerevisiae in vitro has been shown to be S-phase specific, similar to that observed in vivo. We report here a reconstituted in vitro system with partially purified replication proteins, purified replication protein

Putrescine biosynthesis is elevated before DNA replication, and a stimulation of DNA synthesis by 20 mM putrescine has been found using an in vitro DNA synthesizing system. Furthermore, this stimulation of DNA synthesis by putrescine involves a particular factor (factor

A subset of the proteome that binds to specific DNA sequences is at the center of genome function, integrity, and dynamics. We present a detailed protocol that allows the isolation of any specific DNA binding protein and its subsequent identification

In studies of the regulation of specific biochemical events by reversible phosphorylation, assaying the protein kinases themselves can often lead to significant progress in understanding the mechanistic details of a system under study. This unit describes assays for a variety
In this research, acid phosphatase was purified and characterized from approximately 3000-year-old human bones from archeological excavations. Using anion exchange chromatography, two isoenzymes, TrACP and TsACP, were isolated from the bone. TrACP and TsACP were eluted separately, with a concentration
