Hello Mingyue,
I sincerely appreciate you for forwarding the email to me. I would be delighted to assist in any way possible.
Dear Sini,
Thank you for your interest in the GRAB sensors. May I kindly inquire if you require a red-shifted GRAB-sensor for Ado?
In addition to the published green (cpEGFP-based) GRAB Ado sensors (Ado1.0, https://www.science.org/doi/10.1126/science.abb0556; Ado1.0m, https://www.pnas.org/doi/10.1073/pnas.2212387120 ), I am excited to inform you that my labmate Bohan Li has recently developed an incredibly promising red version (cpRFP-based), known as rAdo1.5 (unpublished). Attached are some data for your perusal.
As the probe is yet to be published, we would prefer to share it through a collaboration. Please let us know if you are interested in obtaining the unpublished red version.
Warm regards, Zhaofa
