Phospholamban is a 52 amino acid integral membrane protein that regulates the Ca2 pump in cardiac muscle and skeletal muscle cells. When phospholamban is phosphorylated by protein kinase A (PKA) its ability to to inhibit the sarcoplasmic reticulum calcium pump (SERCA) is lost. Thus, activators of PKA, such as the beta-adrenergic agonist epinephrine (released by sympathetic stimulation) may enhance the rate of cardiac myocyte relaxation.Additionally, since SERCA is more active, the next action potential will cause an increased release of calcium resulting in increased contraction (positive inotropic effect). When phospholamban is not phosphorylated, such as when PKA is inactive, it can interact with and inhibit SERCA.

Human Cardiac phospholamban (PLN) ELISA Kit employs a two-site sandwich ELISA to quantitate PLN in samples. An antibody specific for PLN has been pre-coated onto a microplate. Standards and samples are pipetted into the wells and anyPLN present is bound by the immobilized antibody. After removing any unbound substances, a biotin-conjugated antibody specific for PLN is added to the wells. After washing, Streptavidin conjugated Horseradish Peroxidase (HRP) is added to the wells. Following a wash to remove any unbound avidin-enzyme reagent, a substrate solution is added to the wells and color develops in proportion to the amount of PLN bound in the initial step. The color development is stopped and the intensity of the color is measured.
