Title (EN) A CELL-BASED ASSAY AND KITS FOR ASSESSING SERUM ANTICHOLINERGIC ACTIVITY
(FR) DOSAGE À BASE DE CELLULES ET KITS D'ÉVALUATION DE L'ACTIVITÉ ANTICHOLINERGIQUE SÉRIQUE
Abstract:
(EN) Provided herein are methods for determining the level of muscarinic acetylcholine receptor subtype- (M1 receptor) anticholinergic activity in a blood serum sample, the method comprising the steps of removing protein from the blood serum sample by treatment with perchloric acid (PCA) to produce a PCA-treated serum sample; incubating the PCA-treated serum sample with a membrane preparation from cultured cells expressing the M1 receptor and an M1 receptor ligand; detecting an amount of binding of the M1 receptor ligand to the M1 receptor and comparing the amount of binding to a standard to determine the level of M1 receptor anticholinergic activity in the blood serum sample. Also provided are kits for performing the method.
(FR) La présente invention concerne des procédés pour déterminer le niveau d'activité anticholinergique du sous-type du récepteur muscarinique de l'acétylcholine (récepteur M1) dans un échantillon de sérum sanguin, le procédé comprenant les étapes consistant à éliminer la protéine de l'échantillon de sérum sanguin par traitement avec de l'acide perchlorique (PCA) pour produire un échantillon de sérum traité par PCA ; à incuber l'échantillon de sérum traité par PCA avec une préparation de membrane à partir de cellules cultivées exprimant le récepteur M1 et un ligand de récepteur M1 ; à détecter une quantité de liaison du ligand du récepteur M1 au récepteur M1 et à comparer la quantité de liaison à une norme pour déterminer le niveau de l'activité anticholinergique du récepteur M1 dans l'échantillon de sérum sanguin. L'invention concerne également des kits permettant de mettre en œuvre le procédé.
