Establishment of deficient cells using Cre recombinase and floxed mouse derived cells (2017/06/23 T.M.)
- Has2 deficient cells were established by using Cre recombinase expressing AxCANCre adenovirus. Mouse Has2 gene floxed allele cells were segregated from the transgenic mice having the exon 2 flanked by two loxP sites. And then the cells were infected with AxCANCre adenovirus carrying the Cre recombinase to remove the exon 2.[more]

M-INK, a novel tool for tagging the mature melanosomes.(2017/05/02 N.N.)
- A novel tool "M-INK" to visualize melanosome in melanocyte and keratinocyte has arrived.[more]
G-CaMP, a fluorescent calcium sensor.(2017/03/16 N.N.)
- A Fluorescent probes "G-CaMP" for measuring intracellular calcium concentration are available.[more]
- The G-CaMPs are calcium sensor proteins consisting of Calmodulin (CaM) calcium-binding region, M13 fragment of myosin light chain kinase and fluorescent protein. In the original paper, G-CaMPs were used to observe cardiomyocytes differentiated from iPS cells (Shiba, Y. et al, 2016) and neurons of zebrafish (Muto, A. et al, 2011).

Construction of reporter gene having long promoter by using BAC clone and with recombineering technique.(2017/02/28 T.M.)
- Luciferase reporter assay is a powerful tool for real-time monitoring of gene expression in living cells. It is recommended to construct reporter gene with lager promoter but hard to do so by means of common cloning technique. In this article, 20 kb promoter of Hprt gene was retrieved and cloned into a luciferase reporter by using BAC clone and with recombineering technique.[more]
A fluorescent probe to evaluate activity of autophagy. (2017/02/21 N.N.)
- Plasmid clone of a novel probe capable of evaluating the activity of autophagy by GFP/RFP signal ratio has arrived.[more]
Green- and Red-emitting luciferases with luminescence. (2017/2/2 T.M.)
- Now, we offer five novel luciferase genes of fireflies. The luciferases hold high luminescence and stability in a wide pH range.

♦ Fluorescent Ubiquitination-based Cell Cycle Indicator (Fucci) by single plasmid.(2016/6/20 T.M.)
- Fucci2a cell cycle phase markers allow visualization and estimation of cell cycle progress by observation of green and red fluorescent proteins. [more...]
- This plasmid express two distinct colored fluorescent proteins, one of which fused to Cdt1 degron, another one of which fused to Geminin degron. Therefore, the transfectant indicate distinct color fluorescence between the cell (G1) and the cell (S/G2/ M).
