OBJECTIVE To study the tissue pathology of breast lesions associated with hydrophilic polyacrylamide gel injection augmentation mammoplasty. DESIGN Retrospective study. SETTING Private anatomical pathology practice, Hong Kong. PATIENTS Eight patients who underwent lumpectomy of the breast due to complications of hydrophilic polyacrylamide gel injection for augmentation mammoplasty. MAIN...
SDS-polyacrylamide gel electrophoresis (SDS-PAGE) transfer method was used for purification and enrichment of the protein from crude sample. Coomassie bluc/ZnSO4 stained protein band(s) containing intact polyacrylamide gel were loaded on to another polyacrylamide gel either alone or as pooled gel bands. Two/three bands were combined together and arranged tightly over one another, sealed with st...
We describe a platform for high-throughput electrophoretic mobility shift assays (EMSAs) for identification and characterization of molecular binding reactions. A photopatterned free-standing polyacrylamide gel array comprised of 8 mm-scale polyacrylamide gel strips acts as a chassis for 96 concurrent EMSAs. The high-throughput EMSAs was employed to assess binding of the Vc2 cyclic-di-GMP ribos...
The flat gel acrylamide electrophoresis technique was standardized and applied to the comparison of four species of porcine mycoplasmas. Clear differences were observed between these species, and differences were seen among the strains of Mycoplasma hyosynoviae. The clarity of the patterns and the number of bands developed was influenced by the amount of protein in the extract and the age of th...
Probably the most widely used of techniques for analyzing mixtures of proteins is SDS polyacrylamide gel electrophoresis. In this technique, proteins are reacted with the anionic detergent, sodium dodecylsulfate (SDS, or sodium lauryl sulfate) to form negatively charged complexes. The amount of SDS bound by a protein, and so the charge on the complex, is roughly proportional to its size. Common...
D ISCOT1XUOUS ELECT1IO1’HORESIS in polyacrylamide rods has been used for separation of serum proteins (1). In spite of satisfactory resolution in tile rod, the technic renhains cumbersome, and comparison of the closely migrating cOnlpoflents inaccurate. Akroyd (2) reported discontinuous electrophoresis On polyacrylamide gel slab, which alleviates many of the difficulties of the rod. We llave co...
Sodium dodecyl sulphate-polyacrylamide gel electrophoresis (SDS-PAGE) is a universally used method for determining approximate molecular weight (MW) in protein research. Migration of protein that does not correlate with formula MW, termed "gel shifting" appears to be common for histidine-rich proteins but not yet studied in detail. We investigated "gel shifting" in Ni2+-binding histidine-rich H...
Twenty-three control samples of CSF were analyzed by vertical column electrophoresis on acrylamide gel. Quantitation results using a microdensitometer are presented. The normal protein pattern shows 15 constant bands which coincide in mobility and in many cases in staining pattern with serum proteins. The haptoglobin peaks, except for the band of the 1-1 type and the leading band of the 2-1 typ...
