Calmodulin (CaM) purified from porcine brain and biotinylated using NHS ester-activated biotin with an 8 atom spacer arm. A ubiquitous, calcium-binding protein that interacts with and regulates a wide variety of proteins, thus affecting different cellular functions and calcium-calmodulin-dependent signaling pathways. CaM mediates several biological processes, such as inflammation, apoptosis, muscle contraction, intracellular movement, short-term and long-term memory, nerve growth, and the immune response. Useful for enzyme activation, CaM binding studies, and general assessment of CaM-dependent signaling pathways. Biotin/Protein Ratio: 0.5-1.0 as determined by HABA assay.
