Signosis' FewCell TF Activation Plate Arrays provide an innovative solution for research projects with limited cell numbers. This array, coupled with the integration of Whole Cell Lysis Buffer, enable precise profiling of multiple transcription factor activations even with as few as 1000 cells. The FewCellTF activation profiling plate array II by Signosis is designed for this purpose and can monitor the activation of 96 different TFs, including important regulators like NFkB, AP1, HIF1, and p53. This array is different from the TF Activation Profiling Plate Array I as it focuses on a specific subset of TFs, which can be useful for studying specific cellular pathways or diseases.
