General description

2,2′-Dithiobis(5-nitropyridine) is an aromatic disulphide.

Application

2,2′-Dithiobis(5-nitropyridine) was employed:
  • as cysteine-activating reagent to study the NMR of G protein-coupled receptors
  • in the deprotection assays for protected selenocysteine-containing peptides
  • for deprotecting p-methoxybenzyl groups and acetamidomethyl groups from the side-chains of cysteine and selenocysteine
  • to remove the p-methoxybenzyl protecting group from cysteine and selenocysteine side-chains

Ca(2+)-activated K+ currents (IK(Ca)) and voltage-dependent Ca(2+)-insensitive K+ currents (IK(V)) were recorded using the patch clamp technique to study the pulmonary (PASMC) and ear arterial smooth muscle cells (EASMC) of the rabbit and the possible regulatory mechanisms related to hypoxia.

Functional modifications of neuronal P/Q-type voltage-dependent Ca2+ channels expressed in Xenopus oocytes by oxidation were examined electrophysiologically. Oxidation by external H2O2 enhanced the whole-oocyte currents through the Ca2+ channels composed of the alpha1A, alpha2/delta, and beta3 subunits at negative voltages

The effects of cysteine-modifying reagents on the gating of rat cloned Kv1.4 channels expressed in HEK-293 cells were examined using the whole-cell patch-clamp technique. Cells transfected with Kv1.4 expressed a rapidly inactivating K+ current with a mid-point of activation of
