STA-21 is a small molecule inhibitor that is of interest in the field of biochemistry and cell biology research. It is known to inhibit the signal transducer and activator of transcription 3 (STAT3), which is a protein critically involved in cellular processes such as proliferation, survival, and differentiation. Researchers utilize STA-21 to study the STAT3 signaling pathway and its role in cellular communication. By inhibiting STAT3, STA-21 helps in dissecting the downstream effects of this pathway and in identifying the genes regulated by STAT3 transcriptional activity. It is also employed in studies aimed at understanding the molecular mechanisms that contribute to the aberrant activation of STAT3, which is observed in various cell signaling disorders.

I dissolved sc-200757(STA-21) completely in DMSO. When I added my solution to cell culture media a yellow crystal precipitate appeared. Do you have any recommendations?

Asked by: Chemsynth123
Thank you for your question. STA-21 (CAS 28882-53-3): sc-200757 is soluble in DMSO up to 20mg/mL. Using a lower inhibitor concentration my prevent precipitation when adding the DMSO solution to cell culture media.
