50 µg specific antibody, lyophilized. Affinity purified with the immunogen. Albumin and azide were added for stabilization. For reconstitution add 50 µl H2O to get a 1mg/ml solution in PBS. Then aliquot and store at -20°C to -80°C until use. Antibodies should be stored at +4°C when still lyophilized. Do not freeze! |

A significantly higher effective resolution can be achieved with a standard microscope setup. For additional experimental details, please refer to the Remarks section.', $event)" style="cursor: help;">ExM: 1 : 100 (see remarks) gallery In antibody-based DNA-PAINT (Point Accumulation in Nanoscale Topography), a short oligomeric docking strand is coupled to a specific antibody. The transient association of the fluorophore to the antibody is mediated by the pairing of a short fluorescently labeled complementary imager DNA strand. DNA-PAINT allows super-resolution imaging and the imaging of a huge number of antibodies on the same biological sample in a single multiplex experiment. For additional experimental details refer to the Remarks section.', $event)" style="cursor: help;">DNA-PAINT: yes (see remarks) Electron microscopy (EM) is a microscopy technique that detects the scatter of electrons through thin tissue sections. In Immuno-EM the antigen is usually revealed by colloidal gold conjugated secondary antibodies linking electron dense structures to antigen-bound primary antibodies.', $event)" style="cursor: help;">EM: yes gallery |
Immunogen | Recombinant protein corresponding to AA 1921 to 2212 from rat Ca2+ channel P/Q-type α-1A (Cav2.1) (UniProt Id: P54282) |
Reactivity |
Reacts with: rat (P54282), mouse (P97445). Other species not tested yet. |
Specificity | K.O. validated PubMed: 27537483 |
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 P/Q-type alpha-1A aggregates after boiling, making it necessary to run SDS-PAGE with non-boiled samples. |
Data sheet | 152_203.pdf |
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-1A isoform occurs in VGCCs of the P/Q-type while isoform α-1B is found in the N-type. Both belong to the high voltage activated group (hva).
