Background

Two isoforms of the vitamin D-dependent Ca-binding proteins have been described so far: calbindin D28k, also referred to as CALB 1, D-28k, and CAB 27, and calbindin D29k, also known as calretinin. These proteins are expressed in cells that have to handle a high calcium influx such as brain, bone, teeth, inner ear and others. Calbindins are believed to regulate cellular activity by suppressing or buffering intracellur calcium. In the brain calbindin D28k is a useful marker for specific neuronal cell types. It is particularly concentrated in the dendrites and perikarya of cerebellar Purkinje cells, but is also found in many GABAergic interneurons in the cortex.

Cat. No. 214 003	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 up to 1 : 5000 (AP staining) gallery IP: yes ICC: 1 : 5000 gallery IHC: 1 : 500 gallery IHC-P: 1 : 500 gallery Clarity: 1 : 300 (see remarks) Western blot (WB); separation of proteins by PAGE and subsequent transfer to a membrane. Detection of target molecules is carried out with antibodies. Some antibodies require special sample preparation steps. For details, please refer to the “Remarks” section. Immunoprecipitation (IP); Immunoisolation or pulldown of a target molecule using an antibody. For details and product specific hints, please refer to the ”Remarks” section. Immunocytochemistry (ICC) on 4% PFA fixed cells. Immunoreactivity is usually revealed by fluorescence. Some antibodies require special fixation methods. For details, please refer to the “Remarks” section. Immunohistochemistry (IHC) on 4% PFA perfusion fixed tissue with 24h PFA post fixation. Immunoreactivity is usually revealed by fluorescence or a chromogenic substrate. Some antibodies require special fixation methods or antigen retrieval steps. For details, please refer to the ”Remarks” section. Immunohistochemistry (IHC-P) of formalin fixed, paraffin embedded (FFPE) tissue (some antibodies require special antigen retrieval steps, please refer to the ”Remarks” section). Immunoreactivity is usually revealed by fluorescence or a chromogenic substrate. Clarity is a sample preparation method for clearing, immunolabeling and volume imaging of large biological samples. Clearing is carried out by SDS and Focusclear treatment. For additional experimental details, please refer to the Remarks section.
