The Bioinformatics & Drug Design Lab provides an integrated bioinformatics analysis and drug design platform focusing on the following five aspects: constructing an comprehensive and large biomedical data warehouse; data mining techniques for extraction of useful results from large amounts of biological data; undertaking assay of  omics, including proteomics and metabolomics; dealing with methods for storing, retrieving and analyzing biological data, such as nucleic acid and protein sequences, structures, functions, pathways and genetic interactions; computer-aided drug design (CADD) technology from the availability of bioinformatics applications.

Ø Biomedical Database

We construct biomedical data warehouse by collecting and integrating databases of different biomedical domains. By now, these biomedical databases including SinoMed, PubMed, OMIM, GO, NCI pathway interaction database, MeSH, PubChem, TCMDB, PDB, ChEMBL, PharmaGKB, TTD, DrugBank, UniProt, UMLS and KEGG.

Ø Data Mining

Based on the biomedical database, typical text mining tasks include text categorization, text clustering, concept / entity extraction, sentiment analysis and document summarization are performed to derive high-quality information from these texts.

Ø Assay of Proteomics & Metabolomics

The lab provides a comprehensive analysis platform for protein and metabolite. Two widely used and powerful methods, including Gas chromatography (GC) and High performance liquid chromatography (HPLC) are used for separation in the lab. Furthermore, Mass spectrometry (MS) is applied to identify and to quantify metabolites after separation by GC, HPLC. Also several statistical programs are available for analysis of MS data.

Ø Bioinformatics Analysis

By applying computationally intensive techniques, we develop new algorithms and statistics with which to assess relationships among members of large data sets, to increase the understanding of biological processes. Also commercial software, such as ingenuity pathway analysis (IPA) is often used for casual network analysis, comparison analysis, upstream regulator analysis, mechanistic networks and pathway analysis.

Ø Computer-Aided Drug Design

With understanding the structure of small molecules, proteins and nucleic acids, we apply computer-aided drug design (CADD) technology to discover or design active compounds to cure the diseases. To further understand the mechanism of effects of drug / drug combination on biological network, we also develop structure- based technology to identify targets of compounds from drug / drug combination.

Ø  Name: Ultra High Performance Liquid Chromatograph with Ultra High Definition Accurate Mass Qquadrupole Time-of-

    Flight MassSpectrometer (UHPLC UHD Q-TOF MS)

Ø  Location: Rm. 707, SCM

Ø  Contact: Mr. CL Chan (clchan@hkbu.edu.hk)

Ø  Description: Discover unmatched speed and sensitivity for qual and quant. Incorporating breakthrough Agilent iFunnel

    technology, the Agilent 6540 Q-TOF LC / MS system delivers the lowest detection levels of any high resolution LC / MS

    instrument. For the first time ever, we can achieve low femtogram-level sensitivity with high resolution and accurate

    mass. It’s the ideal choice for pharmaceutical, metabolite ID, discovery proteomics, metabolomics, food safety,

    forensics, toxicology and environmental screening applications.

Ø  Name: Gas Chromatograph with Electron Capture Detector and Ion Trap MassSpectrometer (GC-ECD / Ion Trap MS)

Ø  Location: Rm. 707, SCM

Ø  Contact: Mr. CL Chan (clchan@hkbu.edu.hk)

Ø  Description: The 6300 Series Ion TrapLC / MS is a complete LC / MS / MS system. The hardware includes an optional

    Agilent 1200 Series LC, the ion trap mass spectrometer and the data system. Additionally, the Ion Trap LC / MS

    comes with a syringe pump for both low-flowand high-flow direct infusion work. The software includes the Trap

    Control program for trap control, data acquisition, data analysis, quantitative analysis and the Agilent ChemStation

    program for sample automation and LC control.

Ø  Name: 2D Nanoflow High Performance Liquid Chromatograph with Chip Electrospray Ionisation Source for Ionisation

    Source for Mass Spectrometer (2D Nano-HPLC Chip ESI)

Ø  Location: Rm. 707, SCM

Ø  Contact: Mr. CL Chan (clchan@hkbu.edu.hk)

Ø  Description: Electrospray ionization (ESI) is a main stay of LC / MS. It can be used to analyze large and small

    analytes, and can achieve excellent sensitivity and robust, reliable performance. It can generate both positive and

    negative ions, and ion polarity can be switched on a scan-by-scan basis to double the information acquired from a

    single run. A dual-nebulizer ESI source is available for TOF and Q-TOF instruments. The second nebulizer is

    dedeicated to the continuous introduction of a reference mass to ensure the best possible mass accuracy.
