Clone Host Grade Applications
Monoclonal Mouse Affinity Purified B IP IF
Phospholamban (PLB) is a 52 amino acid phosphoprotein which regulates the calcium pump of cardiac sarcoplasmic reticulum (SR). PLB is an oligomer of five identical subunits each having a cytoplasmic and transmembrane domain. The cytoplasmic domain (residues 1-25) contains the phosphorylation sites and is highly basic and readily cleaved by proteases; whereas the transmembrane domain (residues 25-52) is mostly hydrophobic, protease resistant and stabilizes the pentamer. Following adrenergic stimulation of cardiac muscle, PLB is phosphorylated at Ser16 and at Thr17 which is correlated with stimulation of calcium transport activity across the SR membrane and relaxation of cardiac fibers.
Catalog #P4073-52
ApplicationsSuitable for use in Immunofluorescence, Western Blot and Immunoprecipitation. Can also be used to increase the calcium uptake in ventricular SR vesicles analogous to the phosphorylation of PLB following adrenergic stimulation.
Other applications not tested.
Recommended DilutionImmunofluorescence: 20ug/ml; Immunofluorescence staining of PLB in rat papillary muscle tissue results in diffuse staining of the network sarcoplasmic reticulum (SR).
Western Blot: 2ug/ml; Detects a 25kD protein under non-reducing conditions representing the pentameric form of PLB and a 5kD protein under reducing conditions representing the monomeric form of PLB in canine cardiac extracts.
Optimal dilutions to be determined by the researcher.
Storage and StabilityMay be stored at 4°C for short-term only. For long-term storage and to avoid repeated freezing and thawing, aliquot and store at -20°C. Aliquots are stable for at least 12 months at -20°C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer.
