Key elements and design rationale

• Antibody format: Rabbit Polyclonal Rabbit IgG
• Immunogen / epitope context: E.coli-derived human CaV1.3 recombinant protein (Position: M1-I180). Human CaV1.3 shares 99% and 98%amino acid (aa) sequence identity with mouse and rat CaV1.3, respectively. (reported region: M1-I180).
• Molecular weight context: reported MW: 245 kDa; calculated MW: 245141 MW
• Reactivity: Human,Mouse,Rat
• Applications: Flow Cytometry, IHC, ICC, WB

As a polyclonal antibody, the reagent recognizes multiple epitopes on the target, which can improve detection robustness but may increase sensitivity to sample-dependent epitope changes.

Biological background

Voltage-dependent L-type calcium channel subunit alpha-1D; Voltage-dependent L-type calcium channel subunit alpha-1D. CACNA1D is also known as PASNA, SANDD or Cav1.3. Voltage-dependent calcium channels mediate the entry of calcium ions into excitable cells, and are also involved in a variety of calcium-dependent processes, including muscle contraction, hormone or neurotransmitter release, and gene expression. Calcium channels are multisubunit complexes composed of alpha-1, beta, alpha-2/delta, and gamma subunits. The channel activity is ed by the pore-forming alpha-1 subunit, whereas the others act as auxiliary subunits regulating this activity. The distinctive properties of the calcium channel types are related primarily to the expression of a variety of alpha-1 isoforms, namely alpha-1A, B, C, D, E, and S. This gene encodes the alpha-1D subunit. Several transcript variants encoding different isoforms have been found for this gene. Functional note: Voltage-sensitive calcium channels (VSCC) mediate the entry of calcium ions into excitable cells and are also involved in a variety of calcium-dependent processes, including muscle contraction, hormone or neurotransmitter release, gene expression, cell motility, cell division and cell death. The isoform alpha-1D gives rise to L-type calcium currents. Long-lasting (L-type) calcium channels belong to the 'high-voltage activated' (HVA) group. They are blocked by dihydropyridines (DHP), phenylalkylamines, benzothiazepines, and by omega-agatoxin-IIIA (omega-Aga-IIIA). They are however insensitive to omega-conotoxin- GVIA (omega-CTx-GVIA) and omega-agatoxin-IVA (omega-Aga-IVA). . Reported localization: Membrane ; Multi-pass membrane protein . Expression/tissue context: Expressed in pancreatic islets and in brain, where it has been seen in cerebral cortex, hippocampus, basal ganglia, habenula and thalamus. Expressed in the small cell lung carcinoma cell line SCC-9. No expression in skeletal muscle. .

Common research applications

• Western blotting: compare relative CACNA1D (Voltage-dependent L-type calcium channel subunit alpha-1D) levels across conditions; band patterns may reflect isoforms and processing.
• IHC/IHC-F: assess spatial distribution of CACNA1D (Voltage-dependent L-type calcium channel subunit alpha-1D) across tissue regions and cell types using matched controls.
• IF/ICC: evaluate subcellular localization and co-localization patterns; signal can depend on fixation/permeabilization and epitope accessibility.
• Flow cytometry: quantify target-positive populations and shifts in expression; gating strategy and background staining controls are essential.

Notes for experimental interpretation

• Specificity notes: No cross reactivity with other proteins.
• Cross-reactivity: No cross-reactivity with other proteins
• Isoforms and PTMs: Apparent size and signal patterns can differ across splice isoforms, proteolytic processing, and post-translational modifications.
• Controls: Include an isotype control (as relevant), no-primary control for imaging, and orthogonal validation such as KD/KO samples when available.
