Cat. No. 152 103 |
50 µg specific antibody, lyophilized. Affinity purified with the immunogen. Albumin was 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! |

Immunogen | Recombinant protein corresponding to AA 856 to 888 from mouse Ca2+ channel P/Q-type α-1A (Cav2.1) (UniProt Id: P97445) |
Reactivity |
Reacts with: rat (P54282), mouse (P97445). Other species not tested yet. |
Specificity | K.O. validated PubMed: 22701595 |
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_103.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).
