Cellular biochemistry methods for investigating protein tyrosine phosphatases.

abstract：:Cells oxidize molecules to generate energy and to make the materials to build and support the structures and functions needed for life. However, unwanted oxidations can damage these same structures and impair function. Lipids (the lipids in membranes and lipoproteins) are targets of unwanted oxidations. The primary me...
