S9-A13 is a highly potent and specific inhibitor of SLC26A9, potently inhibits SLC26A9-mediated Cl−/I− and Cl−/SCN− exchange activities with IC50 of 90.9 and 171.5 nM, respectively.S9-A13 does not inhibit other members of the SLC26 family and has no effects on Cl− channels such as CFTR, TMEM16A, or VRAC.S9-A13 (0-1 uM ) inhibits SLC26A9 currents in a dose-dependent manner in HEK293 cells, but shows little effects on CFTR currents in HEK293 cells at the highest concentration (5 uM).S9-A13 has a minor effect on ion transport in human airway epithelial cells and mouse trachea, despite clear expression of SLC26A9 in the apical membrane of ciliated cells.

Providing storage is as stated on the product vial and the vial is kept tightly sealed, the product can be stored for up to 24 months.
Wherever possible, you should prepare and use solutions on the same day. However, if you need to make up stock solutions in advance, we recommend that you store the solution as aliquots in tightly sealed vials at -20°C.
