Immunogen Human Ankyrin B Spectrin Binding Domain Peptide
Clone 43862
Isotype IgG1
Cross-Reactivity Rat (Rattus)
Characteristics 1. Since applications vary, each investigator should titrate the reagent to obtain optimal results.
2. Please refer to us for technical protocols.
3. Caution: Sodium azide yields highly toxic hydrazoic acid under acidic conditions. Dilute azide compounds in running water before discarding to avoid accumulation of potentially explosive deposits in plumbing.
Purification Purified from tissue culture supernatant or ascites by affinity chromatography.
Alternative Name Ankyrin B
Background Ankyrins are a family of proteins which were first discovered in erythrocytes and shown to bind to spectrin, a primary component of the cytoskeletal architecture. They have since been shown to be expressed at very high levels in the vertebrate brain and are also found in other cell types. Ankyrins function by acting as adaptors to link integral membrane proteins, including cell adhesion and ion channel molecules to the cytoskeleton. The structure of ankyrin consists of three domains, two highly conserved N-terminal and one C-terminal variable domain. The conserved regions contain a membrane-binding domain of ~89-95 kDa and a spectrin-binding domain of ~62 kDa, while the variable region has pre-mRNA alternative splice sites. Two ankyrins have been extensively characterized: ankryin R is the product of the ANK1 gene and is primarily expressed in the brain, although alternatively spliced forms are found in erythrocytes, ankyrin B is the product of the ANK2 gene, located on a different chromosome from ANK1, and is primarly expressed in neonatal and adult brain but is also found in heart, lymphocytes and platelets. Studies done on ankyrinB (-/-) knockout mice, which die by postnatal day 21, have demonstrated a link between the L1 cell adhesion molecule and ankyrin B in premyelinated axons. Isoforms of ankyrin B have been reported to be detectable ranging from approximately 440, 220, 150 and 110 kDa in western blot analysis, depending on the tissue-type of origin. This antibody is routinely tested by western blot analysis.
Molecular Weight 110-440 kDa
Application Notes Neonatal rat brain membranes are suggested for use as the positive control.

anti-Ankyrin 2, Neuronal (ANK2) antibody Western blot analysis of Ankyrin B. Rat brain lysates were probed with 2 µg/ml (lane 1) or 5 µg/ml (lane 2) of the mouse anti-ankyrin B antibody (clone 2.20). Ankyrin B isoforms can be observed at ~150 and ~220 kDa, respectively.
