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 I by Signosis serves as a powerful tool for monitoring the activation of 48 different transcription factors simultaneously. This array encompasses well-known transcription factors such as NFkB, AP1, HIF1, and p53, pivotal in a diverse range of cellular processes. By simultaneously monitoring the activation of multiple transcription factors, researchers can attain a more comprehensive understanding of the regulatory networks governing gene expression and cellular signaling.
