Produktbeschreibung

Weitere Bezeichnung: CACNB4 (CACB4) (c-terminal region)

Swiss-Prot: O00305

Immunogen: A synthetic peptide from the c-terminal region of human CACNB4 (CACB4, Voltage dependent L-type calcium channel subunit beta-4) conjugated to an immunogenic carrier protein was used as the immunogen. The antigen is homologous in many species including mouse and rat.

Format: Lyophilized

Beschreibung: FUNCTION: The beta subunit of voltage-dependent calcium channels contributes to the function of the calcium channel by increasing peak calcium current, shifting the voltage dependencies of activation and inactivation, modulating G protein inhibition and controlling the alpha-1 subunit membrane targeting. Defects in CACNB4 are associated with susceptibility to idiopathic generalized epilepsy (IGE). IGE is characterized by recurring generalized seizures in the absence of detectable brain lesions and/or metabolic abnormalities. Generalized seizures arise diffusely and simultaneously from both hemispheres of the brain. Defects in CACNB4 are a cause of juvenile myoclonic epilepsy (EJM). EJM is a subtype of idiopathic generalized epilepsy. Patients have afebrile seizures only, with onset in adolescence (rather than in childhood) and myoclonic jerks which usually occur after awakening and are triggered by sleep deprivation and fatigue. Tissue specificity: Expressed predominantly in the cerebellum and kidney. Also known as: CACB4, Voltage-dependent L-type calcium channel subunit beta-4, Calcium channel voltage-dependent subunit beta 4.

Spezifität: Appears to be specific for CACNB4.

Anwendungen

Applikationshinweise: IHC, WB. A dilution of 1: 300 to 1: 2000 is recommended. The optimal dilution should be determined by the end user. Not yet tested in other applications.

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
