Abstract: A LED control circuit includes an LED array circuit and a control circuit. The LED array circuit has a plurality of parallel branches, each of which has a constant-current regulator, an LED and an FET connected together in series, wherein the constant-current regulator supplies a steady current to the corresponding LED and the FET can control the respective LED to be put out or lighted up. The control circuit includes a microprocessor and a temperature sensor. The temperature sensor is connected with the microprocessor and located near the LEDs of the LED array circuit for detecting the temperature of the LEDs and transmitting the temperature signals to the microprocessor. The microprocessor is connected with the FETs of the LED array circuit for controlling the corresponding FETs to be repeatedly on or off according to the temperature signals in order to regulate the temperature of the corresponding LEDs respectively.

Abstract: A cell detecting system is herein disclosed, wherein a complex is formed with a first bioactive ligand coupling to a quantum dot and recognizing and coupling to a first receptor of a cell and a second bioactive ligand coupling to a magnetic bead and recognizing and coupling to a second receptor of the cell. The magnet is configured for attracting the complex. A quantum dot measuring system configured for measuring the fluorescence of the complex includes an excitation light source, an optical system, a detecting sensor and a data capturing unit, wherein the detecting sensor includes a photomultiplier tube measuring florescence of the quantum dot excited by the excitation light source. The present invention achieves the goal of specific cell detection with high sensitivity without performing cell incubation. A quantum dot measuring system is also herein disclosed.

Abstract: Production in E. coli of a lipidated fusion protein containing a lipidating sequence derived from Ag473 and a target polypeptide.

Abstract: Production of a lipidated protein in an E. coli strain adapted to membrane protein expression.

Abstract: An immunopeptide containing a cytotoxic T lymphocyte epitope derived from HPV E6 or HPV E7 protein. The immunopeptide can be used as a component of a vaccine for enhancing immune responses against HPV or treating HPV-associated diseases. Also within the scope of this invention are a nucleic acid encoding the immunopeptide and an antibody specific to the CTL epitope.

Abstract: A consensus peptide sequence designed for domain III of the envelope proteins of four serotypes of dengue virus and used in a vaccine against multiple serotypes of dengue virus is disclosed. The vaccine is able to elicit cross-neutralization antibody responses against multiple serotypes of dengue virus.
