Antibodies were produced in rabbits immunized with physostigmine conjugated to bovine serum albumin (BSA) by two different methods: a diazo immunogen coupled to BSA with carbodiimide and a Mannich coupled immunogen. Both immunogens produced antibodies that could be used to develop sensitive and spec
While the L-arginine conversion assay has been utilized to measure nitric oxide synthase (NOS) activity in isolated enzyme and pure cell preparations, this method often fails to provide accurate measurements in whole tissues. Biological tissues contain variable amounts of unlabeled substrate and enz
