  • Auxin Inducible Degron (AID) System
    • Using the AID System, you can degrade proteins fused with a degron (a small domain that can induce protein degradation) in a very short period of time.
  • ChIP-seq analysis
    • ChIP-seq analysis of genomic binding regions of five major transcription factors highlights a central role for ZIC2 in the mouse epiblast stem cell gene regulatory network.

      RDB15774 pCAGGS-BLRP-BirA Expression vector to perform ChIP-seq analysis using biotinylated proteins.

      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.

    • These luciferases have at most four-time maximum luminous intensity than that of widely used luciferase of the Photinus pyralis, a common North American firefly. Further more, Green-, Yellow- or Red-emission can be obtained by using D-luciferin as a substrate of each luciferase.
  • AkaLuc luciferase providing brighter and red-shifted luminescence
    • The artificial bioluminescence system AkaBLI enables noninvasive signal observation in deep tissue of living animals. It was developed by Dr. Atsushi Miyawaki and Dr. Satoshi Iwano of the RIKEN Center for Brain Science, and Dr. Shojiro Maki of the University of Electro-Communications. The AkaBLI consists of an artificial substrate AkaLumine with improved tissue permeability and an artificial luciferase Akaluc optimized to AkaLumine. The intensity of the luminescence of AkaBLI system is 100 to 1000 folds brighter than the conventional systems.
  • Nano-lantern luminescent and fluorescent protein
    • Nano lantern (NL) consists of Renilla luciferase and adjacent fluorescence protein. The chemiluminescence of the luciferase provides light source for excitation and enables the fluorescence protein to be observed. Three colors of NLs, yellow, cyan and orange, have been developed. NLs do not require external light source and overcome problems such as autofluorescence, phototoxicity, and photobleaching.
