Target description

Calmodulin (UniProt: P0DP23; also known as CaM, Calmodulin 1) is encoded by the CALM1 (also known as CALM, CAM, CAM1) gene (Gene ID: 801, 805, 808) in human. Calmodulin (CaM), a small 17 kDa ubiquitous Ca2+-binding protein that serves as a major physiological effector for a wide range of cellular responses. It acts as an intracellular Ca2+ receptor and transduces Ca2+ transients, usually in response to growth factors. It mediates the activity of a number of Ca2+ regulating enzymes, including protein kinases, phosphatases, nitric oxide synthases, and phosphodiesterase. CaM is a dumb-bell shaped molecule with two globular domains at the amino and carboxyl termini that are connected by a long central eight-turn -helix. CaM can bind four molecules of Ca2+ with high affinity. The Ca2+binding sites are arranged in pairs, with each pair located in a globular domain. In vertebrates, the Ca2+binding sites in the carboxy-terminal lobe are reported to have a slightly higher affinity for Ca2+ than the pair of Ca2+binding sites at the amino-terminal lobe. Upon binding of Ca2+, CaM undergoes a conformational change, exposing a hydrophobic region on the molecule, which is rich in methionine. This hydrophobic region is believed to be involved in the binding of CaM to protein receptor molecules. The high methionine content of two hydrophobic regions on the globular domains creates a flexible, yet sticky interaction surface. It allows CaM to interact with a variety of proteins, without placing high demands on the specificity of the interaction. Therefore, Ca2+/CaM can bind effectively to the CaM-binding domains of all its target proteins, in spite of their lack of amino acid sequence homology. CaM′s ability to recognize CaM-binding domains is further improved by the intrinsic flexibility of the central linker region, which allows the two domains of CaM to slide over the surface of the a-helical bound peptide to find the most favorable binding orientation. This ZooMAb^® recombinant monoclonal antibody, generated by our propriety technology, offers significantly enhanced specificity, affinity, reproducibility, and stability over conventional monoclonals.

Physical form

Purified recombinant rabbit monoclonal antibody IgG, lyophilized in PBS, 5% Trehalose, normal appearance a coarse or translucent resin. The PBS/trehalose components in the ZooMAb formulation can have the appearance of a semi-solid (bead like gel) after lyophilization. This is a normal phenomenon. Please follow the recommended reconstitution procedure in the data sheet to dissolve the semi-solid, bead-like, gel-appearing material. The resulting antibody solution is completely stable and functional as proven by full functional testing. Contains no biocide or preservatives, such as azide, or any animal by-products. Larger pack sizes provided as multiples of 25 μL.

Reconstitution

300 μg/mL after reconstitution at 25 μL per vial. Please refer to guidance on suggested starting dilutions and/or titers per application and sample type.

Storage and Stability

Recommend storage of lyophilized product at 2-8°C; Before reconstitution, micro-centrifuge vials briefly to spin down material to bottom of the vial; Reconstitute each vial by adding 25 μL of filtered lab grade water or PBS; Reconstituted antibodies can be stored at 2-8°C, or -20°C for long term storage. Avoid repeated freeze-thaws.
