Genome Biology Unit (GBU) initiated in 2010 and is a node of national Biocenter Finland Genome-wide methods network (GWM) and a part of GoEditStem platform of HiLIFE at University of Helsinki. GBU provides genome-scale cDNA/ORF clones and related services, digital slide scanning, training and user support. For more information please visit our website:

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.

2. Digital slide scanning service: In 2014 GBU started digital slide scanning service (Pannoramic 250 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.
