Background Information

CA1(Carbonic anhydrase 1) is also named as CAB and belongs to the alpha-carbonic anhydrase family, which may reside in cytoplasm, in mitochondria, or in secretory granules, or associate with membranes in cell. It forms a large family of genes encoding zinc metalloenzymes of great physiologic importance. Extracellular CA1 mediates hemorrhagic retinal and cerebral vascular permeability through prekallikrein activation(PMID:17259996).

Using the CA-1 primary antibody with mouse colon scrapes yielded very clean bands with western blotting. Immunofluorescence also gave a fairly clean, detectable signal, with CA-1 showing up along the brush border in mouse colon tissue. There were some cells that stained more intracellularly, and unsure if that was non-specific binding of the antibody, or another cell type other than colonocytes that expresses CA-1 intracellularly.

  • Primary Antibody Dilution: 1:1000 (WB) and 1:100 (IF)
