Description

General description

17 kDa

Calmodulin (CaM) is a ubiquitous, calcium-binding protein that can bind to and regulate a multitude of different protein targets, thereby affecting many different cellular functions.
CaM mediates processes such as inflammation, metabolism, apoptosis, muscle contraction, intracellular movement, short-term and long-term memory, nerve growth and the immune response. CaM is expressed in many cell types and can have different subcellular locations, including the cytoplasm, within organelles, or associated with the plasma or organelle membranes. Many of the proteins that CaM binds are unable to bind calcium themselves, and as such use CaM as a calcium sensor and signal transducer. CaM undergoes a conformational change upon binding to calcium, which enables it to bind to specific proteins for a specific response. CaM can bind up to four calcium ions, and can undergo post-translational modifications, such as phosphorylation, acetylation, methylation and proteolytic cleavage, each of which can potentially modulate its actions.

Immunogen

Epitope: a.a. 128-148

Synthetic peptide corresponding to the 21 carboxy-terminal amino acids (128-148) of bovine calmodulin, conjugated with tyroglobulin.

Application

Detect Calmodulin using this Anti-Calmodulin Antibody validated for use in WB & IP.

Immunoprecipitation:
4 μg of a previous lot immunoprecipitated calmodulin from A431 RIPA cell lysate. Radioimmunoassay:
Use 10 μg/mL to detect calmodulin in the range of 200-300 ng.

Analysis Note

Control
Positive Antigen Control: Catalog #12-301, non-stimulated A431 cell lysate. Add 2.5µL of 2-mercaptoethanol/100µL of lysate and boil for 5 minutes to reduce the preparation. Load 20µg of reduced lysate per lane for minigels.

Evaluated on human A431 carcinoma cells, RIPA lysates from mouse 3T3 and L6 rat skeletal fibroblasts.

Western Blot Analysis: 0.1-1 μg/mL of this antibody detected calmodulin in RIPA lysates from human A431 carcinoma cells. Previous lots detected calmodulin in RIPA lysates from mouse 3T3 and L6 rat skeletal fibroblasts.
