General description
Dihydropyridine Receptor (DHPR) is a heteropentamer calcium ion channel and comprises of α1,α2/δ,β and γ subunits. It is localized in the skeletal muscle in the t-tubule membrane. The α2subunit of DHPR is a glycosylated subunit and is anchored on the membrane.
Specificity
Reacts specifically with the α2 subunit of the DHP receptor. Strong reactivity is observed with the α2 subunit in rat, mouse, guinea pig, rabbit skeletal and cardiac muscle, and rat brain and lung tissue. Weaker reactivity is observed with rat kidney, liver and spleen tissues. By immunohistochemistry, double rows of discrete punctate staining represent pairs of triads on the opposing sides of the Z-lines.
Immunogen
Rabbit dihydropyridine (DHP) receptors, (α2 subunit)
Application
Applications in which this antibody has been used successfully, and the associated peer-reviewed papers, are given below.
Western Blotting (1 paper)
Western Blotting (1 paper)
Monoclonal Anti-Dihydropyridine Receptor (α2 Subunit) antibody produced in mouse has been used in:
- immunofluorescent histochemistry
- surface plasmon resonance binding
- immunohistochemistry (IHC)
- immunoblotting
Use of this antibody for immunoblot analysis will allow for detection of a 220 kDa band (native conditions) or a 143 kDa band (denaturing conditions).Use of this antibody for immunohistochemistry of muscle tissue will demonstrate double rows of discrete punctate staining representing pairs of triads on the opposing sides of the Z-lines are observed.
Biochem/physiol Actions
Dihydropyridine Receptor (DHFR) α1 subunit is the voltage-sensor. DHPR interacts with ryanodine receptor (RyR) and also mediates excitation-contraction (EC) coupling in cardiac and skeletal muscles. Mutation in the DHPR (E1014K) affects its affinity and selectivity towards calcium permeation. Additionally, it also plays a key role in the synaptic transmission.
Physical form
Solution in phosphate buffered saline containing 0.05% sodium azide.
Other Notes
This mouse monoclonal IgG2a antibody is supplied as a mouse ascites diluted in phosphate buffered saline containing 0.05% sodium azide as a preservative.

Relapse to cocaine seeking is associated with potentiated excitatory synapses in nucleus accumbens. α2δ-1 is an auxiliary subunit of voltage-gated calcium channels that affects calcium-channel trafficking and kinetics, initiates extracellular signaling cascades, and promotes excitatory synaptogenesis. Previous data demonstrate that

Local anesthetics, which are widely known to be neuronal voltage-gated Na(+) channel blockers, also affect a variety of other ion channels, N-methyl-d-asparate (NMDA) receptors and α-amino-3-hydroxy-5-methyl-4-izoxazolepropionic acid (AMPA) receptors. Glutamate, which is released from presynaptic fibers, activates extracellular signal-regulated kinase
