Product Overview
This rabbit polyclonal antibody recognizes voltage-dependent calcium channel subunit alpha-2/delta-2 (gene CACNA2D2) in human, mouse and rat samples and is validated for ELISA, flow cytometry, IHC, ICC/IF and Western blot. The predicted molecular weight is 129.8 kDa, and the supplier reports an observed band at about 130 kDa.
CACNA2D2 encodes the alpha-2/delta-2 auxiliary subunit of voltage-gated calcium channels. It promotes trafficking of channel complexes to the cell surface and shapes their current density and gating, with P/Q-, N- and L-type channels among its partners. It is studied in neuronal excitability, epilepsy and cerebellar function.

Samples with a confirmed band (WB): human MCF-7 cells.
Recommended loading (WB): 20–40 µg of total protein per lane.
Conditions in the example images (WB): 5–20% gradient SDS-PAGE under reducing conditions, 50 µg lysate per lane, transfer to nitrocellulose membrane, blocking in 5% non-fat milk, primary antibody at 0.5 µg/mL overnight at 4 °C, HRP-conjugated secondary antibody at 1:10000, ECL detection.
Samples with a confirmed signal (flow cytometry): A549 cells.
Immunogen
Recombinant human CACNA2D2 fragment (Gln66–Gln284), expressed in E. coli.
Reactivity Notes
The supplier lists reactivity with human, mouse and rat. UniProt places voltage-dependent calcium channel subunit alpha-2/delta-2 in the membrane. Tissue expression noted by UniProt (human): Predominantly present in cerebellar cortex. The samples tested by the supplier (listed above) are a practical starting point for positive controls.
