Small volumes of anti-Cacnb2 antibody vial(s) may occasionally become entrapped in the seal of the product vial during shipment and storage. If necessary, briefly centrifuge the vial on a tabletop centrifuge to dislodge any liquid in the container`s cap. Certain products may require to ship with dry ice and additional dry ice fee may apply.

Background Info: Detects ~78 kDa. No cross reactivity against Cavbeta1, Cavbeta3, Cavbeta4

Scientific Background: Cav Beat subunits are involved in the transport of the pore forming alpha1 subunit to the plasma membrane (3). They also shield an ER Retention signal on the alpha1 subunit, thereby guiding the pore-forming subunit to the target membrane (4, 5). They also determine the biophysical properties of the calcium channel (5).

auxillary subunit of the L-type Ca(2+) channel [RGD, Feb 2006]

CACNB2: 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 CACNB2 are the cause of Brugada syndrome type 4 (BRGDA4). A heart disease characterized by the association of Brugada syndrome with shortened QT intervals. Brugada syndrome is a tachyarrhythmia characterized by right bundle branch block and ST segment elevation on an electrocardiogram (ECG). It can cause the ventricles to beat so fast that the blood is prevented from circulating efficiently in the body. When this situation occurs (called ventricular fibrillation), the individual will faint and may die in a few minutes if the heart is not reset. Belongs to the calcium channel beta subunit family. 8 isoforms of the human protein are produced by alternative splicing.
