b-cyclodextrin glucosyl transferase (b-CGTase) hydrolyses starch to produce b-cyclodextrin by transglycosylation (cyclization) activity. The conventional method for detection of b-CGTase activity is based on detecting starch hydrolysis by iodine staining. This method reveals all amylolytic enzymes, but can not discriminate them. In the present study, we introduce a new method for specific detec...

This work suggests the use of chitosan gel imbued with the photosensitizer Photogem and with the antibiotic Tetraclin as a possible drug delivery system. The results reveal a decrease in the photosensitizer level of toxicity. Besides, the interaction between Photogem and chitosan gel causes a red shift in the photosensitizer spectrum, increasing its absorption in the therapeutic window (600-700...

We have further characterized the sensitivity and specificity of SYPRO Orange protein gel stain and SYPRO Red protein gel stain with native and 2-dimensional polyacrylamide gels and for staining gels prior to Western blot analysis. We found that nucleic acids are not stained by the SYPRO protein gel stains, in contrast to results obtained with commonly used silver staining techniques. Bacterial...

BACKGROUND Currently available injectable fillers have demonstrated limited durability. This report proposes the in vitro culture of human adipose-derived stem cells (hASCs) on hyaluronic acid (HA) gel for in vivo growth of de novo adipose tissue. METHODS For in vitro studies, hASCs were isolated from human adipose tissue and were confirmed by multi-lineage differentiation and flow cytometry....

We demonstrate the facile tuning of uniform Bragg reflection color from red to blue by uniaxial compression gel films containing single-crystalline loosely packed colloidal crystals. The tuned colors can be fixed photopolymerization a polymer precursor solution contained in compressed films.

Erythroid ferritin was isolated from tadpole red blood cells, an unusually abundant source, with an iron content of 12%. The apoprotein was characterized by sedimentation equilibrium studies, sodium dodecyl sulfate gel electrophoresis, and by determination of amino acid composition. Tadpole red cell apoferritin has a molecular weight of 478,000, a subunit size of 19,600, and an amino acid compo...
