Seeking a Principle Investigator (indefinite-term position), Gene Engineering Division (RIKEN BRC Gene Bank) (2019/07/26 T.M.)

New Director Appointed (2019/04/01 T.M.)

Congratulations to Distinguished Professor Tasuku Honjo for the 2018 Nobel Prize! (2018/10/3 T.M.)

  • The 2018 Nobel Prize in Physiology or Medicine for the discovery of cancer therapy by inhibition of negative immune regulation

Genetic resources regarding the prize are available (2018/10/3 T.M.)

Dnaconda’s Recommendationdnaconda01

Fluorescent protein probe that can visualize the multiple inter-organelle contact sites in cells. (2019/3/29 N.N.)

  • Divided GFP-fragment have a feature that they emit fluorescence again by reconstitution when each fragment is in close proximity.

Recombinant protein expression vector in fruit fly cell line, S2. (2019/2/22 T.Y.)

  • The Drosophila culture cell (S2) is widely used for recombinant mammalian proteins, because of more chance to get active protein than bacteria and more chance to get free from interactors than mammalian culture cells. Here, authors introduce three additional tools (see below) for original pMT-PURO (cat# RDB08532) to aim more effective transfection and more stable transfectant during cultivation.

Expression vector of optogenetics technique (2019/1/11 N.N.)

  • New plasmids developed by Dr. Toru Ishizuka of Tohoku University are available.[more…]

mCherry expression vector with Cre/loxP system (2018/12/07 S.H.)

  • Dr. Yumiko Hatanaka and her colleagues at Osaka University developed mCherry expression vector with Cre/loxP system.[more…]

Genetic resources to visualize organelle (2018/11/13 N.N.)

  • We are providing genetic resources for visualization of 15 organelles such as mitochondria and nucleus. Each clone contains an organelle localization signal sequence fused with fluorescent proteins or epitope tags. Organelles can be detected by fluorescence or by detecting epitope tags with antibodies.

Function of transcription coactivator TAZ on the regulation of IL1B expression. (2019/5/13 T.M.)

  • Involvement of YAP on the phenotype of malignant mesothelioma (MM) has been demonstrated. However, the function of TAZ, a paralog of YAP, in MM cells has not been clarified. [more…]

HMGA1 influences urokinase plasminogen activator system throught the regulation of PLAU and SERPINE1 gene. (2019/4/12 T.M.)

  • HMGA1 is a oncofetal architectural transcription factor and has a role in controling genes in many of aspects of neoplastic transformation. [more…]

Quantitative evaluation of autophagic activity(2019/2/1 N.N.)

  • In order to visualize autophagosome and observe autophagy, MAP1LC3 (LC3) fused with fluorescent proteins as a probe are used. However, the fluorescence of the probe attenuates during autophagy progresses and it is not suitable for quantitative assay of autophagy.
  • Dr. Noboru Mizushima and his colleagues at the University of Tokyo developed a new probe that can expresses GFP-LC3 and RFP-LC3ΔG (lacking glycine (G) at the LC 3 end) simultaneously at equimolar amounts.[more…]

Akaluc luciferase providing brighter and red-shifted luminescence (2018/5/7 N.N.)

  • Firefly bioluminescence systems have been commonly used as a imaging tool of biological phenomena. However, it have not been strong enough for imaging signals in deep tissues, because of low permeabilization of substrates. Recently, Dr. Atsushi Miyawaki and Dr. Satoshi Iwano of the RIKEN Center for Brain Science, and Dr. Shojiro Maki of the University of Electro-Communications developed a system of artificial bioluminescence AkaBLI that enables noninvasive signal observation in deep tissue of living animals.

Stable ChIP-seq analysis using transcription factors tagged with biotinylated peptide tag. (2018/2/8 K.N.)

  • ChIP-seq is a powerful method of comprehensive analysis of transcription factor (TF) binding sites. However, the bottle neck of ChIP-seq analysis is the quality of antibody, and thus many researchers have been given up. To overcome, authors constructed the vector expressing “biotinylated-tag” transcription factors. With this vector, you can get acceptable level of TF-DNA complex for ChIP-seq analysis by streptavidin-beads for any kinds of TF.[more]

Fluorescent probes for sphingomyelin and cholesterol lipid domains.(2018/02/06 N.N.)

  • Lipid rafts are small lipid domains on the cell membrane and are thought to play an important role in signal transduction, endocytosis and more. Because of the lack of appropriate probes to label sphingomyelin and cholesterol individually, detailed analysis of lipid rafts was difficult.[more]
