isolation of cell free fetal dna (cffdna) from maternal serum usually leads to very low concentrations of dna impeding further resolving through conventional methods of electrophoresis. although several protocols have been described for capillary electrophoresis (ce) of double stranded dna, they usually need using special polymers or coated capillaries which degrade over time. herein, we propos...

Pauci-immune crescentic glomerulonephritis (PICGN) is most commonly associated with antineutrophil cytoplasmic antibodies (ANCA). We report a case of chronic, sclerosing ANCA-negative PICGN discovered when a patient presented with multiple myeloma. A 57-year-old woman presented with complaints of nausea, emesis and weakness. She was found to be in renal failure with a serum creatinine of 9.4 mg...

OBJECTIVES To determine the most clinically effective diagnostic testing strategy for plasma cell disorders in the clinical laboratory. METHODS Serum and urine samples from 2,799 patients with suspected plasma cell dyscrasias were tested by alternative diagnostic testing strategies consisting of serum protein electrophoresis (SPE) with either urine protein electrophoresis (UPE) or serum free ...

PURPOSE Previous studies have demonstrated deposition of tear proteins onto worn contact lenses. In this study, we used proteomic techniques to analyze the protein deposits extracted from worn daily wear silicone hydrogel contact lenses in combination with different lens care solutions. METHODS Worn lenses were collected and protein deposits extracted using urea and surfactant. Protein extrac...

Current understanding of the final oxidative steps leading to lignin deposition in trees and other higher plants is limited with respect to what enzymes are involved, where they are localized, how they are transported, and what factors regulate them. With the use of cell suspension cultures of sycamore maple (Acer pseudoplatanus), an in-depth study of laccase, one of the oxidative enzymes possi...

Amyloidosis is a systemic illness characterized by the extracellular deposition of abnormal proteins in body tissues and organs. In addition to renal involvement, amyloidosis can also present with a variety of skin manifestations, though rarely with alopecia. Sixteen cases of alopecia secondary to systemic amyloidosis are reported. There is one reported case that presented with alopecia univers...

Here we set forth the first from a series of reports devoted to history capillary electrophoresis. In this opening part, go more than two centuries back in time and revisit original discoveries electrolysis, electrophoresis electroosmosis. We emphasize essential role brilliant invention 1799 by Alessandro Volta, Voltaic pile, basically battery delivering constant-flow electricity, which has mad...

we have modified one of the most useful methods of protein separation; namely, two dimensional gel electrophoresis (2-de). this modified version of 2-de is not only simpler and easier but also faster than all the currently available methods. in this method, isoelectric focusing is carried out in the first dimension using a vertical sodium dodecyl sulfate polyacrylamide gel electrophoresis (sds-...
