The Department of Biological Services provides specialized facilities and services to more than 700 scientists and students in the areas of bioinformatics, molecular biology, protein analysis, cell biology, bacteriology, genomics and immunology. The specific services include DNA sequencing, Protein sequencing, Mass spectroscopy analysis (including peptide synthesis quality control, protein molecular mass determination, protein identification and identification of post translational modifications), Oligonucleotide synthesis, Peptide synthesis, Bioinformatics consaltation (given as 1:1 consultation or in the format of lectures and workshops), Cell sorting (analytical and preparative), Antibody preparation (polyclonal and monoclonal), Bacterial fermentation, irradiation of cells, animals and other biological materials, Gene expression profiling by DNA array analysis and maintenance of electronic equipment and computers.

In addition, staff members of various units of the Biological Services provide courses through the Fienberg Graduate School. Example of such courses are programming, basic bioinformatics analysis, DNA array handling and results analysis and cell sorting. The Bioinformatics unit hosts the Israeli National Node (INN), which maintains a comprehensive collection of DNA and protein databases and programs. Together with the Genome Center the Bioinformatics unit works on the development of tools used for databases searching.

Most of our services are available to scientists from other academic institutions and to the industry. Public databases are freely accessible through the web.

During the last year we have replaced two old irradiation facilities were replaced with two state of the art irradiators that are designed for self-operation a feature that will result in saving manpower. In addition a new cell sorter was installed that will enable a much faster and more efficient cell separation. The Bacteriology unit was moved from its old temporary location to a new highly equipped facility.abilities. A new DAPSAS computer, which was installed last year, was activated.
