General description

SCR7 pyrazine is an inhibitor of DNA ligase IV.

Application

SCR7 pyrazine has been used as a non-homologous end joining (NHEJ) modulator to study its effect on CRISPR/Cas9-mediated editing.
SCR7 pyrazine has been shown to enhance CRISPR genome editing efficiency. To see other small molecule CRISPR enhancers, visit sigma.com/CRISPR-enhancers.

Biochem/physiol Actions

SCR7 pyrazine is reported to be an inhibitor of non-homologous end joining (NHEJ) and has been shown to enhance the efficiency of CRISPR-Cas9 genome editing.
SCR7 pyrazine is reported to be an inhibitor of non-homologous end joining (NHEJ) and has been shown to enhance the efficiency of CRISPR-Cas9 genome editing. The effect of SCR7 pyrazine on the efficiency and targeting precision of CRISPR applications has been shown to be cell type specific and context dependent. SCR7 pyrazine is a product of spontaneous cyclization of SCR7, first reported by Srivastava, M., et al.
