Hi Eduardo,

I hope you are doing well.

I regret to inform you that the expansion of nTregs has once again failed using the two donors we previously used. This indicates that there may be some issues with our system. We have decided to conduct some internal validations for this assay before proceeding with the formal assay using your compounds.

Due to the delay caused by the failure of Treg expansion and the need for internal testing, we would like to offer you a 10% discount. We hope this compensates for any inconvenience caused.

Thank you for your understanding in this matter. Please don't hesitate to reach out if you have any further questions.

Best regards, [Your Name
