Description:

Stem cells are important cells characterized by their ability to self-renew or differentiate into many cell types, which is governed by intracellular signaling pathway and transcription regulation. Hence, transcription regulation plays a determining role in conferring cellular identity and function. The step-wise maturation of stem cells into terminally differentiated cell types requires the timely activation of a cascade of transcription programs governed by lineage-specifying transcription factors. Multiple transcription factors and target genes have been widely reported to associate with stem cell self-renewal and pluripotency including EGR1, OCT4, FOXD3, FOXO, Nanog, SOX2, SOX18, ETS, GLI, KLF4, MEF2, Myc, RNUX1, Pax6, TCF/LEF and GATA. However, stem cells are precious and limited.

Principle:

Signosis’ stem cell TF activation profiling plate array is used for monitoring the activation of multiple TFs simultaneously. In the technology, a series of biotin-labeled probes are made based on the consensus sequences of TF DNA-binding sites. When the probe mix incubates with the cell lysate, individual probes will find its corresponding TF and form TF/probe complexes, which can be easily separated from free probes through simple spin column purification. The bound probes are detached from the complex and analyzed through hybridization with a plate; each well is specifically pre-coated with complementary sequences of the probes. The captured DNA probe is further detected with streptavidin-HRP. Luminescence is reported as relative light units (RLUs) on a microplate luminometer.
