Apart of classical action at GABA-A receptors, bicuculline methobromide (BIC) can be used as a tool to reveal presence of alpha2 glycine receptor (GlyR) subunit.In our work we transfected HEK cells with alpha2 and beta GlyR subunits to obtain heteromeric GlyRs. Application of glycine triggered a clear receptors response, but subsequent addition of BIC decreased response amplitude by >95% (see image). This confirmed expression of alpha2 subunits and their incorporation into active GlyRs.
