A general strategy to red-shift green fluorescent protein based biosensors

BioRxiv : the Preprint Server for Biology
S. Zhang, Hui-wang Ai


Compared to green fluorescent protein (GFP) based biosensors, red fluorescent protein (RFP) based biosensors are inherently advantageous because of reduced phototoxicity, decreased autofluorescence, and enhanced tissue penetration. However, there is a limited choice of RFP-based biosensors and development of each biosensor requires significant effort. Herein, we describe a general and convenient method which uses the genetically encoded amino acid, 3-aminotyrosine (aY), to convert GFPs and GFP-based biosensors into red.

Brain Injury & Trauma

brain injury after impact to the head is due to both immediate mechanical effects and delayed responses of neural tissues.
