A set of 1118 human transcription factors was made by our expression system to study side effects of "thalidmide"

Category: Announcements Created: Friday, 22 January 2021

A joint effort by several universities and research institutes in Japan, including our strategic technology partners Dr. Satoshi Yamanaka and Professor Tatsuya Sawasaki at the Proteoscience Center of Ehime University, conducted a comprehensive study using a human protein array comprising 1,118 human transcription factors produced in our wheat germ cell-free protein expression system. Screening those proteins led to the discovery that thalidomide and its metabolite 5‐hydroxythalidomide induce teratogenicity via the cereblon neosubstrate PLZF.


Thalidmide was originally used as a sleeping drug for pregnant women but had caused terrible side effects. Later it was found that Thalidmide and its derivatives are potent drugs for treating leprosy and multiple myeloma. These are highly effective drugs that are now sold for about 1 trillion yen per year in the world for treatment of blood cancers such as multiple myeloma. However, these drugs require a strict safety management to avoid teratomas. The new finding reported here will help to develop better thalidmide derivatives that could avoid any risk for teratoma formation.

2022 Season Greeting

Our way of saying thank you.


With the year ending, we want to thank you for working together with CellFree Sciences and express our sincere wishes for the Seasons and a Happy, Healthy and Prosperous New Year!


This year had been complicated for all of us with life been very much dominated by the ongoing COVID-19 pandemic and the suffering it had broad to many people worldwide. But there is also hope in the times of the pandemic, which showed more than ever the importance of life sciences and the contribution we can make to bring the pandemic to an end. It fills us with pride that also our wheat germ cell-free expression system is used in the response to the COVID-19 pandemic to prepare viral proteins for research and the development and production of diagnostic products now available on the Japanese market. CellFree Sciences is committed to keep on supporting medical research and to work for better solutions in global health.


CellFree Sciences will start into 2022 with new service for protein-protein interaction assay with using protein array and campaign for custom synthesis service.


We all at CellFree Sciences are looking forward to being at your service again in 2022 supporting your important projects with our reagents and services. Please contact us and let us know about your needs and requirements. It is our commitment to work for our customers and partners to make your projects successful.

With all the very best wishes for you and yours for a better New Year 2022 from all of us at CellFree Sciences!


Our wheat germ cell-free expression system was used in a study to clarify the side effects of thalidomide.

Category: Announcements Created: Tuesday, 06 October 2020

Furihata, H., Yamanaka, S., Honda, T. et al. published in Nature Communications the results from a jointed project conducted by researchers at the University of Tokyo, Nagoya Institute of Technology, and our strategic partner the Proteo-Science Center at Ehime University using structural biology for determining the mechanisms behind side effects of immunomodulatory drugs like Thalidomide and its metabolite 5-hydroxythalidomide.


Thalidomide is used as an effective anti-cancer drug for treatment of multiple myeloma, although it exhibits side effects that cause developmental disorders in children during pregnancy. It is hoped that the results will help in the future to design better immunomodulatory drugs that mitigate the side effects.

The development serological markers for detecting recent Plasmodium vivax infection has been successful

Category: Press releases Created: Tuesday, 12 May 2020

The international research group comprising of Proteo-Science Center, Ehime University’s Dr. Eizo Takashima, Dr. Masayuki Morita, and Dr. Takafumi Tsuboi along with CellFree Sciences Co., Ltd.’s Dr. Matthias Harbers succeeded in developing a serological diagnostic marker that can identify those with dormant liver stage infections, which are the causes of Plasmodium v​​ivax recurrences.


This result has been achieved by an international joint research project with the main members including Proteo-Science Center, Ehime University, CellFree Sciences Co., Ltd., The Walter and Eliza Hall Institute of Medical Research (WEHI), Pasteur Institute, and Foundation for Innovative New Diagnostics (FIND).

Further, this project was started with assistance from the Global Health Innovative Technology Fund (GHIT Fund) between October 2015 and March 2017.


This research result allows the diagnosis of Plasmodium v​​ivax’s dormant liver stage parasites which has been a difficult challenge in eliminating malaria, for the first time in the world. It can be seen as an important result to safely and effectively promote the treatment.


The paper regarding this research result has been published on the May 12th (Tues.) 2020 issue of the Nature Medicine.

Development and validation of serological markers for detecting recent Plasmodium vivax infection
