Cat. No. 152 404	100 µl antiserum, lyophilized. For reconstitution add 100 µl H₂O, then aliquot and store at -20°C until use. Antibodies should be stored at +4°C when still lyophilized. Do not freeze!
Applications	WB: 1 : 500 up to 1 : 1000 (see remarks) gallery IP: not tested yet ICC: not tested yet IHC: not tested yet IHC-P: not tested yet Western blot (WB); separation of proteins by PAGE and subsequent transfer to a membrane. Detection of target molecules is carried out with antibodies. Some antibodies require special sample preparation steps. For details, please refer to the “Remarks” section. Immunoprecipitation (IP); Immunoisolation or pulldown of a target molecule using an antibody. For details and product specific hints, please refer to the ”Remarks” section. Immunocytochemistry (ICC) on 4% PFA fixed cells. Immunoreactivity is usually revealed by fluorescence. Some antibodies require special fixation methods. For details, please refer to the “Remarks” section. Immunohistochemistry (IHC) on 4% PFA perfusion fixed tissue with 24h PFA post fixation. Immunoreactivity is usually revealed by fluorescence or a chromogenic substrate. Some antibodies require special fixation methods or antigen retrieval steps. For details, please refer to the ”Remarks” section. Immunohistochemistry (IHC-P) of formalin fixed, paraffin embedded (FFPE) tissue (some antibodies require special antigen retrieval steps, please refer to the ”Remarks” section). Immunoreactivity is usually revealed by fluorescence or a chromogenic substrate.
Immunogen	Recombinant protein corresponding to AA 1921 to 2222 from rat Ca2+ channel R-type α-1E (Cav2.3) (UniProt Id: Q07652)
Reactivity	Reacts with: rat (Q07652), mouse (Q61290). Other species not tested yet.
Remarks	WB: Due to its large size, this antibody requires special gel-electrophoresis and Western blot protocols for visualization by immunoblotting. Excellent results can be obtained with the 4-12% TRIS-glycine gradient gels of anamed or NuPage TRIS-acetate gels from Invitrogen. Ca2+ channel R-type alpha-1E aggregates after boiling, making it necessary to run SDS-PAGE with non-boiled samples. ECL detection is recommended:

Background

Voltage gated calcium channels (VGCCs), also referred to as voltage sensitive calcium channels (VSCCs), are present in most excitable cells. They mediate the influx of Ca²⁺ ions into the cell and trigger the release of neurotransmitters or hormons but are also involved in other calcium dependent processes like metabolism, cell proliferation and cell death.
VGCCs are composed of four subunits (α-1, α-2, β and δ) in a 1:1:1:1 ratio. The α-1E isoform occurs in VGCCs of the R-type which belongs to the high voltage activated group (hva).
