Scientific Data

Immunohistochemistry Calretinin antibody in Human Brain by Immunohistochemistry (IHC-P). View Larger

Calretinin in Human Brain. Calretinin was detected in immersion fixed paraffin-embedded sections of human brain (cortex) using 15 µg/mL Goat Anti-Human/Mouse/ Rat Calretinin Antigen Affinity-purified Polyclonal Antibody (Catalog # AF5065) overnight at 4 °C. Tissue was stained with the Anti-Goat HRP-DAB Cell & Tissue Staining Kit (brown; CTS008) and counterstained with hematoxylin (blue).

Western Blot Detection of Human/Mouse/Rat Calretinin antibody by Western Blot. View Larger

Detection of Human/Mouse/Rat Calretinin by Western Blot. Western blot shows lysates of human brain, mouse brain and rat brain tissue. PVDF membrane was probed with 1 µg/mL of Goat Anti-Human/Mouse/Rat Calretinin Antigen Affinity-purified Polyclonal Antibody (Catalog # AF5065) followed by HRP-conjugated Anti-Goat IgG Secondary Antibody (HAF019). A specific band was detected for Calretinin at approximately 31 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 8.

Background: Calretinin

Calretinin (also 29 kDa Calbindin and Calbindin 2) is a 30 kDa member of the EF-hand family of Ca2+-binding proteins. It serves as both an intracellular calcium sensor and calcium buffer. Calretinin is found in cerebellar granule cells plus cortical bipolar and multipolar GABAergic interneurons.

Human Calretinin is 271 amino acids (aa) in length. It contains six EF-hand domains (aa 16 - 270), each of which show a 12 aa Ca2+-binding motif. There are multiple splice variants. One shows a seven aa substitution for aa 181 - 190, accompanied by a 25 aa substitution for the C-terminal Met. Two others show a one and 14 aa substitution for aa 179 - 271, generating a 20 kDa and 22 kDa isoform, respectively. A fourth variant contains a seven aa substitution for aa 185 - 271. Over aa 2 - 177, human and mouse Calretinin show complete aa identity.
