Konfigurierbare Panels & Premixed-Kits
Unser breites Angebot enthält Multiplex-Panels, für die Sie die Analyten auswählen können, die am besten für Ihre Anwendung geeignet sind. Unter einem separaten Register können Sie das Premixed-Cytokin-Format oder ein Singleplex-Kit wählen.
Kits für die zelluläre Signaltransduktion & MAPmates™
Wählen Sie gebrauchsfertige Kits zur Erforschung gesamter Signalwege oder Prozesse. Oder konfigurieren Sie Ihre eigenen Kits mit Singleplex MAPmates™.
Die folgenden MAPmates™ sollten nicht zusammen analysiert werden: -MAPmates™, die einen unterschiedlichen Assaypuffer erfordern. -Phosphospezifische und MAPmate™ Gesamtkombinationen wie Gesamt-GSK3β und Gesamt-GSK3β (Ser 9). -PanTyr und locusspezifische MAPmates™, z.B. Phospho-EGF-Rezeptor und Phospho-STAT1 (Tyr701). -Mehr als 1 Phospho-MAPmate™ für ein einziges Target (Akt, STAT3). -GAPDH und β-Tubulin können nicht mit Kits oder MAPmates™, die panTyr enthalten, analysiert werden.

Background Information
Transient receptor potential cation channel subfamily M member 4 (UniProt: Q9ESQ5; also known as Calcium-activated non-selective cation channel 1, Long transient receptor potential channel 4, LTrpC-4, LTrpC4, MLS2s, Melastatin-like 2) is encoded by the Trpm4 (also known as Ltrpc4) gene (Gene ID: 171143) in rat. TRPM4 is a multi-pass membrane protein with four cytoplasmic domains; six transmembrane domains; and four extracellular domains. Two isoforms of TRPM4 have been described that are produced by alternative splicing. Isoform 1 is highly expressed in the testis tissue with a moderate expression in brain, spleen, and thymus. Isoform 2 is expressed in the brain and spleen. It serves as a calcium-activated non-selective cation channel that mediates membrane depolarization. Although it is a calcium activated channel, it is impermeable to calcium. It mediates the transport of monovalent cations that leads to membrane depolarization. It is reported to participates in T-cell activation by modulating Ca2+ oscillations after T lymphocyte activation, which is required for NFAT-dependent IL-2 production. TRPM4 is also involved in myogenic constriction of cerebral arteries. It plays a role in control of insulin secretion in pancreatic β-cells. It may also be involved in pacemaking activity or could cause irregular electrical activity under conditions of Calcium overload. It is known to affect Th1 and Th2 cell motility and cytokine production through differential regulation of calcium signaling and NFATC1 localization. This polyclonal antibody is reported toblock the channel vua binding to a region close to the channel porefrom extracellular space. Bu blocking TRPM4, it can downregulate TRPM4 surface expression and prevent hypoxia-induced cell swelling. (Ref.: Wei, S., et al. (2020). Front Cell Dev Bio. 8; 562584; Chen, B;et al. (2019).
