Product Information
Format
Affinity Purified
Control
Included free of charge with the antibody is 40 μg of control antigen (lyophilized powder). The stock solution of the antigen can be made up using 100 μL of sterile deionized water. For negative control, preincubate 1 μg of peptide with 10 μg of antibody for one hour at room temperature. Optimal concentrations must be determined by the end user.
Presentation
Affinity purified immunoglobulin. Lyophilized from PBS, pH 7.4, containing 1% BSA and 0.05% sodium azide as a preservative. Reconstitute with 200 μL of sterile deionized water. Centrifuge antibody preparation before use (10,000 xg for 5 min).

Key Applications
Immunocytochemistry
Immunoprecipitation
Western Blotting
Immunohistochemistry (Tissue)
Application Notes
In preparing full-length protein samples for Western blot or immunoprecipitation, the procedures should be performed at 4°C, with the following protease inhibitor mixture: pepstatin A (1 μg/mL), leupeptin (1 μg/mL), aprotinin (1 μg/mL), Pefabloc SC (0.2 mM), benzamidine (0.1 mg/mL), and calpain inhibitors I and II (8 μg/mL each).
Immunoprecipitation
Immunocytochemistry. Recommend subsequent staining with a labeled second antibody.
Western blot: 1.5 to 3.0 μg/mL (1:100-1:200) using ECL
Dilutions should be made using a carrier protein such as BSA (1-3%)
Optimal working dilutions must be determined by the end user.
Biological Information
Immunogen
Purified peptide CNB1 from 851-867 of alpha 1B subunit of rat brain voltage-gated calcium channel (Accession Q02294; Westenbroek et al. 1992) containing N-terminal lysine and tyrosine, conjugated to KLH with gluteraldehyde (Harlow & Lane 1988).
Concentration
Please refer to the Certificate of Analysis for the lot-specific concentration.
Host
Rabbit
Specificity
Recognizes a 1B subunit (both LMW and HMW forms) of voltage-gated calcium channel. Does not cross react with any other calcium channel antigens tested so far.
SPECIES REACTIVITIES: It is expected that the antibody will also work on mouse due to sequence homology (15/17). Other species have not been tested.
Voltage-dependent Ca(2+) channels are multisubunit complexes found in the membrane of many excitable cells that regulate calcium entry (see MIM 601011). N-type calcium channels, which control neurotransmitter release from neurons, are dihydropyridine-insensitive and omega-conotoxin-sensitive. The alpha-1 subunit forms the pore through which calcium enters the cell, and is encoded by a family of at least 5 genes.[supplied by OMIM]
FUNCTION: SwissProt: Q00975 # 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-1B gives rise to N-type calcium currents. N-type calcium channels belong to the high-voltage activated (HVA) group and are blocked by omega-conotoxin-GVIA (omega-CTx-GVIA) and by omega-agatoxin- IIIA (omega-Aga-IIIA). They are however insensitive to dihydropyridines (DHP), and omega-agatoxin-IVA (omega-Aga-IVA). Calcium channels containing alpha-1B subunit may play a role in directed migration of immature neurons. SIZE: 2339 amino acids; 262496 Da SUBUNIT: Multisubunit complex consisting of alpha-1, alpha-2, beta and delta subunits in a 1:1:1:1 ratio. The channel activity is directed by the pore-forming and voltage-sensitive alpha-1 subunit. In many cases, this subunit is sufficient to generate voltage-sensitive calcium channel activity. The auxiliary subunits beta and alpha-2/delta linked by a disulfide bridge regulate the channel activity. Interacts with RIMS1 and RIMBP2 (By similarity). SUBCELLULAR LOCATION: Membrane; Multi-pass membrane protein. TISSUE SPECIFICITY: Isoform Alpha-1b-1 and isoform Alpha-1b-2 are expressed in the central nervous system, but not in skeletal muscle or aorta. DOMAIN: SwissProt: Q00975 Each of the four internal repeats contains five hydrophobic transmembrane segments (S1, S2, S3, S5, S6) and one positively charged transmembrane segment (S4). S4 segments probably represent the voltage-sensor and are characterized by a series of positively charged amino acids at every third position. PTM: Phosphorylated in vitro by CaM-kinase II, PKA, PKC and CGPK (By similarity). SIMILARITY: Belongs to the calcium channel alpha-1 subunit family. & Contains 1 EF-hand domain.

Maintain lyophilized material at -20°C for up to 12 months after date of receipt. After reconstitution maintain at 2-8°C in undiluted aliquots for up to 2 weeks. For longer periods, it is recommended to add glycerol (ACS grade or better) at a ratio of 1:1 and store the antibody at -20°C for up to 6 months. Avoid repeated freeze/thaw cycles.
Elevated expression of type II Na+ channels in hypomyelinated axons of shiverer mouse brain. Westenbroek, R E, et al. J. Neurosci., 12: 2259-67 (1992)
1992
Type I and type III Na+ channels are localized mainly in neuronal cell bodies in mouse brain. Type II channels are preferentially localized in unmyelinated fiber tracts but are not detectable in normally myelinated fibers. In shiverer mice, which lack compact myelin due to a defect in the myelin basic protein gene, elevated expression of type II Na+ channels was observed in the hypomyelinated axons of large-caliber fiber tracts such as the corpus callosum, internal capsule, fimbria, fornix, corpus medullare of the cerebellum, and nigrostriatal pathway by immunocytochemical analysis with subtype-specific antibodies. No difference was observed in the localization of type I and type III Na+ channels between wild-type and shiverer mice. These findings support the hypothesis that type II Na+ channels are preferentially localized in axons of brain neurons and suggest that their density and localization are regulated by myelination. The selective increase in the number of type II channels in hypomyelinated fiber tracts may contribute to the hyperexcitable phenotype of the shiverer mouse.
