General Notes
This product (Catalog No. DPABH-18101) is a rabbit-derived IgG polyclonal antibody raised against human CACNA1A, targeting the amino acid region 1401–1500 of the protein. This antibody exhibits cross-reactivity with CACNA1A from rat, mouse, pig, cow, and rabbit. It has been affinity purified by Protein A. Voltage-dependent calcium channels mediate the entry of calcium ions into excitable cells, and are also involved in a variety of calcium-dependent processes, including muscle contraction, hormone or neurotransmitter release, and gene expression. Calcium channels are multisubunit complexes composed of alpha-1, beta, alpha-2/delta, and gamma subunits. The channel activity is directed by the pore-forming alpha-1 subunit, whereas, the others act as auxiliary subunits regulating this activity. The distinctive properties of the calcium channel types are related primarily to the expression of a variety of alpha-1 isoforms, alpha-1A, B, C, D, E, and S. This gene encodes the alpha-1A subunit, which is predominantly expressed in neuronal tissue. Mutations in this gene are associated with 2 neurologic disorders, familial hemiplegic migraine and episodic ataxia 2. This gene also exhibits polymorphic variation due to (CAG)n-repeats. Multiple transcript variants encoding different isoforms have been found for this gene. In one set of transcript variants, the (CAG)n-repeats occur in the 3' UTR, and are not associated with any disease. But in another set of variants, an insertion extends the coding region to include the (CAG)n-repeats which encode a polyglutamine tract. Expansion of the (CAG)n-repeats from the normal 4-18 to 21-33 in the coding region is associated with spinocerebellar ataxia 6.
DPABH-18101 is suitable for use in IHC-P (1:100–1:500), IHC-F (1:100–1:500), IF (immunofluorescence) (1:100–1:500) applications.
DPABH-18101 is supplied as a liquid formulation in 0.01M TBS (pH7.4) with 1% BSA, 0.02% Proclin300 and 50% Glycerol. For long-term storage, keep at −20 °C. For short-term use, store at 2–8 °C. Avoid repeated freeze–thaw cycles to maintain antibody integrity and performance.
