Ca2+ channel P/Q-type alpha-1A antibody - currently not available - 152 203 K.O.

Polyclonal antibodies are a finite resource. We spend a lot of effort to produce and validate new batches to ensure consistent performance. Sometimes this is not immediately successful, so that temporary supply problems can occur.
Rabbit polyclonal purified antibody
Cat. No.: 152 203
Amount: 50 µg
Price: $405.00
Cat. No. 152 203 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!

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: Tissue sections require additional antigen retrieval with 95% methanol, 5% acetic acid prior to antibody incubation. For details see Dumoulin A, Triller A & Dieudonné S (2001).
ExM: This antibody has been successfully used for the magnified analysis of the proteome (MAP) expansion microscopy method (MAP; Ku et al. 2016. Nature Biotechnology 34:973-981)
DNA-PAINT: This antibody has been successfully used for DNA-PAINT application (see Unterauer et al., 2024; PMID: 38552614).
