Biological Activity

TAT-Gap19(I130A) is a control peptide for TAT-Gap19 (Cat. No. 6227), a Cx43 hemichannel blocker. TAT-Gap19(I130A) consists of TAT-GAP19 with a I130A amino acid residue change at a key residue for GAP19 activity. In C6 glioma cells expression Cx43, TAT-GAP19(1130A) does not inhibit [Ca2+]i-triggered ATP release at 200 μM. TAT-Gap19(I130A) is cell permeable.

Epilepsy Poster

Epilepsy is a brain disease that affects 60 million people globally. More than 20 anti-seizure drugs are currently available, but these do not address the underlying causes of the condition. This poster summarizes current knowledge about the development of the condition and highlights some approaches that have disease-modifying effects in proof-of-concept studies.
