Multiphoton microscope at the Lab of Cancer Biology
We are excited to announce that Olympus FV1200MPE-BX61WI multiphoton microscope of the Lab of Cancer Biology is installed and fully operational. The microscope is optimized for intravital imaging of small laboratory animals and live cell imaging, including 3D imaging of fixed tissue samples. The microscope has XLPLN25xW-MP large diameter objective (NA 1.05; WD 2.00mm; Olympus) designed for multiphoton excitation, Mai Tai DeepSee Ti:Sapphire infrared laser (Spectra-Physics, tuning range 690-1040nm; pulse width 70fs), and a dedicated image analysis computer equipped with Imaris and Adobe Photoshop software. The microscope is open to all qualified researchers interested in studying dynamics of physiological and pathological processes in live multicellular organisms.

Kadri Toome awarded the best poster prize on meeting of Finnish Peptide Society (Helsinki, August 2015)
Kadri Toome and Tambet Teesalu of the laboratory of Cancer Biology participated in the joint symposium of the Finnish Synthetic Chemistry Society, the Medicinal Chemistry Committee of the Finnish Pharmaceutical Society and the Finnish Peptide Society “Emerging targets and molecules in middle space” (Helsinki, Finland, August 24-27, 2015). Kadri’s poster “Development and in vivo validation of blood-brain barrier targeting peptides” (authors: Toome K, Säälik P, Willmore AM, Tarmo Mölder T, Sudakov A, Kõiv K, Nikonov A, Teesalu T) was awarded the best poster prize. Tambet presented an invited talk entitled „Tumor homing peptides v2.0: streamlined discovery and applications for targeted payload delivery”.
