Immunogen: A synthetic peptide from human ChAT (choline O-acetyltransferase) conjugated to an immunogenic carrier protein was used as the immunogen.

Format: Lyophilized

Beschreibung: Cholinergic systems are implicated in numerous neurologic functions. Alteration in some cholinergic neurons may account for the disturbances of Alzheimer disease. The protein encoded by this gene synthesizes the neurotransmitter acetylcholine. Alternative splice variants have been found that contain alternative 5' untranslated exons. Three of the four described splice variants encode identical 69 kDa proteins while one variant encodes both the 69 kDa and a larger 82 kDa protein. Choline acetylase  catalyzes the reversible synthesis of acetylcholine (ACh) from acetyl CoA and choline at cholinergic synapses. CATALYTIC ACTIVITY: Acetyl-CoA + choline = CoA + O-acetylcholine. Defects in CHAT are the cause of familial infantile myasthenia gravis 2 (FIMG2); also known as CMS-EA. FIMG2 patients have myasthenic symptoms since birth or early infancy, negative tests for anti-AChR antibodies, and abrupt episodic crises with increased weakness, bulbar paralysis, and apnea precipitated by undue exertion, fever, or excitement. Inheritance is autosomal recessive. Also known as: CHOACTase, choline acetylase, choline O-acetyltransferase, CMS1A, CMS1A2.

Spezifität: Appears to be specific for ChAT.

Anwendungen

Applikationshinweise: IHC, WB. A dilution of 1: 300 to 1: 2000 is recommended. The optimal dilution should be determined by the end user.

Reinheit: whole serum

Lagerung: Maintain the lyophilised/reconstituted antibodies frozen at -20°C for long term storage and refrigerated at 2-8°C for a shorter term. When reconstituting, glycerol (1:1) may be added for an additional stability. Avoid freeze and thaw cycles.

Beschränkungen: Nur für Forschungszwecke einsetzbar
