"CF-PPiD", a new protein-protein interaction (PPI) screening technology using human protein bead arrays, was reported in an academic paper.

Category: Press releases Created: Saturday, 25 June 2022

A new protein-protein interaction (PPI) screening technology "CF-PPiD" ,which applies "proximity-dependent biotin labeling technology" to the "20K Human Protein Bead Array" containing 20,000 human-derived proteins synthesized by the wheat cell-free synthesis system, has been reported as following academic paper. 

 

CF-PPiD technology based on cell-free protein array and proximity biotinylation enzyme for in vitro direct interactome analysis Scientific Reports volume 12, Article number: 10592 (2022)

https://www.nature.com/articles/s41598-022-14872-w

 

Abstract

Protein–protein interaction (PPI) analysis is a key process to understand protein functions. Recently, we constructed a human protein array (20 K human protein beads array) consisting of 19,712 recombinant human proteins produced by a wheat cell-free protein production system. Here, we developed a cell-free protein array technology for proximity biotinylation-based PPI identification (CF-PPiD). The proximity biotinylation enzyme AirID-fused TP53 and -IκBα proteins each biotinylated specific interacting proteins on a 1536-well magnetic plate. In addition, AirID-fused cereblon was shown to have drug-inducible PPIs using CF-PPiD. Using the human protein beads array with AirID-IκBα, 132 proteins were biotinylated, and then selected clones showed these biological interactions in cells. Although ZBTB9 was not immunoprecipitated, it was highly biotinylated by AirID-IκBα, suggesting that this system detected weak interactions. These results indicated that CF-PPiD is useful for the biochemical identification of directly interacting proteins.

 

※ Now, we, Celfree Science Co. Ltd, are expanding our molecular interaction analysis service using "CF-PPiD" and looking forward to your use of our service.

Season Greetings From CellFree Sciences

Category: Announcements Created: Tuesday, 21 December 2021

 

Season Greetings

From CellFree Sciences!

 

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 assay service by using protein array for protein-protein interaction assay 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!
