Synaptic Systems - Ca2+ channel P/Q-type alpha-1A

Cat. No.: 152 205

Amount: 50 µg

Price: $470.00

Cat. No. 152 205	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!
Applications	WB: 1 : 1000 (see remarks) gallery IP: not tested yet ICC: not tested yet IHC: 1 : 500 (see remarks) gallery IHC-P: not tested yet 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.
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. IHC: This antibody requires mild fixation.

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-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).
