LikesWorked all times I have used this product with very reproducible data! Also appreciated the very quick shipping.- A***e2025-04-10 LikesI used the TL1A in multiple experiments and the results were always consistent and reproducible. Different lots were used throughout a year long timeline and the results did not differ between lots. When shipping there was not ever any damaged packaging that could impact product quality. I have used Acrobiosystems in my professional career multiple times over multiple years and have always had success :) I will continue to use Acro as a trusted supplier.
- E***r2024-08-08 LikesThis protein showed good activity in cell reporter assays and could be used routinely in inhibition assays.
