GBU and its role in Biocenter Finland

The Genome Biology Unit (GBU) initiated in 2010, and is a node of Biocenter Finland Genome-wide methods platform (GWM). We provide technology platform services and reagent collections related to genome-scale approaches.

1. Clones and cloning: GBU's reagent collection contains full-length cDNAs (MGC collection) consisting in about 29 000 clones and a library of open reading frames (ORFeome collaboration) consisting in about 18 600 fully verified clones. The ORF library clones are available in Gateway-based entry vectors and we provide cloning service into various Gateway destination vectors for Biocenter Finland research groups. In addition, GBU maintains and distributes knockdown libraries, which are in-house generated shRNA functional sets against 2500 human and mouse genes.

2. Digital slide scanning service: In 2014 GBU started digital slide scanning service (Pannoramic FLASH II, 3DHIstech). We scan both bright-field and fluorescent slides using either 20x or 40x air objectives. The scanner is equipped with z-stack and extended focus options.

In addition: Drug Discovery Unit and GBU joined forces to acquire a confocal High Content Screening (HCS) microscope, which is currently operated through Light Microscope Unit in the Institute of Biotechnology, University of Helsinki.
