General description

DHP receptor is composed of at least four subunits. The α1 subunit contains the binding site for the DHPs and shows high sequence homology to the voltage gated Na+ channel. The α2 subunit is a large glycoprotein and the other 2 subunits are termed β and γ.


Reacts specifically with the α1 subunit of the DHP receptor. May be used to inhibit the DHP-sensitive calcium current in BC3H1 mouse muscle cells. By immunohistochemistry, double rows of discrete punctate staining represent pairs of triads on the opposing sides of the Z-lines.

Applications in which this antibody has been used successfully, and the associated peer-reviewed papers, are given below.
Immunofluorescence (1 paper)
Monoclonal Anti-Dihydropyridine Receptor (α1 Subunit) antibody produced in mouse is suitable for immunoprecipitation, immunohistochemistry at a working dilution of 1:500 and immunoblotting at 1:2000. It was used for the detection and localization of DHPR-1α by western blotting in skeletal muscle tissue sections of mice in a study. The antibody may be used to inhibit the DHP-sensitive calcium current in BC3H1 mouse muscle cells.

Biochem/physiol Actions

The 1,4-dihydropyridines (DHPs) are synthetic organic compounds which can be used to identify the L-type Ca2+ channels that are found in all types of vertebrate muscle, neuronal and neuroendocrine cells. DHP receptor is part of the L-type calcium channel complex and is thought to be the voltage sensor in E-C coupling.

Physical form

Solution in phosphate buffered saline containing 0.05% sodium azide.
