Chemical genetics reveals a complex functional ground state of neural stem cells.
Nat. Chem. Biol. 3(5) , 268-273, (2007) The identification of self-renewing and multipotent neural stem cells (NSCs) in the mammalian brain holds promise for the treatment of neurological diseases and has yielded new insight into brain cancer. However, the complete repertoire of signaling pathways ... |

Kinetics and model development for enzymatic synthesis of fructo-oligosaccharides using fructosyltransferase.
Bioprocess Biosyst. Eng. 38 , 2417-26, (2015) Experimental investigations were made to synthesize fructo-oligosaccharides (FOS) from sucrose using fructosyltransferase. The influence of various parameters such as temperature (45-55 °C), pH (4-5), initial sucrose concentration (ISC: 300-500 g/L) and enzym... |

A comparison of sugar indicators enables a universal high-throughput sugar-1-phosphate nucleotidyltransferase assay.
Anal. Biochem. 377(2) , 251-258, (2008) A systematic comparison of six sugar indicators for their sensitivity, specificity, cross-reactivity, and suitability in the context of crude lysates revealed para-hydroxybenzoic acid hydrazide (pHBH) to be best suited for application in a plate-based phospha... |

Electrophoretic deposition to promote layer-by-layer assembly for in situ gene delivery application.
Colloids Surf. B Biointerfaces 133 , 171-8, (2015) In this study, layer-by-layer (LbL) assembly of polyelectrolyte was facilitated using electric field assistance (EFA). To elucidate the EFA effects on polyelectrolyte multilayers (PEMs), the electric fields were solely administrated to either chitosan or DNA ... |

Temperature Effects on Kinetic Parameters and Substrate Affinity of Cel7A Cellobiohydrolases.
J. Biol. Chem. 290 , 22193-202, (2015) We measured hydrolytic rates of four purified cellulases in small increments of temperature (10-50 °C) and substrate loads (0-100 g/liter) and analyzed the data by a steady state kinetic model that accounts for the processive mechanism. We used wild type cell... |

Optimal conditions for 4-hydroxybenzoyl- and 2-furoylhydrazine as reagents for the determination of carbohydrates, including ketosamines.
Anal. Biochem. 139(1) , 205-11, (1984) 4- Hydroxybenzoylhydrazine ( PAHBAH ) reacts with glucose in hot aqueous solution when alkali exceeds aroylhydrazine concentration. The related 2- furoylhydrazine ( FAH ) reacts at lower alkali concentrations, making this an attractive alternative carbohydrat... |

New potent inhibitors of tyrosinase: novel clues to binding of 1,3,4-thiadiazole-2(3H)-thiones, 1,3,4-oxadiazole-2(3H)-thiones, 4-amino-1,2,4-triazole-5(4H)-thiones, and substituted hydrazides to the dicopper active site.
Bioorg. Med. Chem. 18 , 4042-8, (2010) A series of 1,3,4-thiadiazole-2(3H)-thiones, 1,3,4-oxadiazole-2(3H)-thiones, 4-amino-1,2,4-triazole-5(4H)-thiones, and substituted hydrazides were tailored and synthesized as new potent inhibitors of tyrosinase. The rationale for inhibitor design was based on... |
