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
Potassium channel Kv1.2 is one of many different types of potassium channels in the cell. The Kv family of potassium channels seem to have a conserved homotetramer formation consisting of four voltage sensors and one pore domain. Kv1.2 cooperates with cortactin (an actin cytoskeleton-binding protein) and together they may have a part in the regulation of the ionic current.

Control
Rat brain membrane tissue lysate
Presentation
Purified mouse monoclonal IgG2bκ in buffer containing 0.1 M Tris-Glycine (pH 7.4), 150 mM NaCl with 0.05% sodium azide.
This Anti-Potassium Channel Kv1.2 Antibody, clone K14/16 is validated for use in IH, WB, IF for the detection of Potassium Channel Kv1.2.
Key Applications
Immunohistochemistry
Western Blotting
Immunofluorescence
Application Notes
Immunofluorescence Analysis: a previous lot of this antibody was used by an independent laboratory in IF. (Yang, J.W., et al. (2007). PNAS. 104(50):20055–20060.)
Biological Information
Immunogen
Recombinant protein corresponding to rat Kv1.2.
Clone
K14/16
Concentration
Please refer to the Certificate of Analysis for the lot-specific concentration.
FUNCTION: Mediates the voltage-dependent potassium ion permeability of excitable membranes. Assuming opened or closed conformations in response to the voltage difference across the membrane, the protein forms a potassium-selective channel through which potassium ions may pass in accordance with their electrochemical gradient.
SUBUNIT STRUCTURE: Heterotetramer of potassium channel proteins. Binds PDZ domains of DLG1, DLG2 and DLG4.
DOMAIN: The N-terminus may be important in determining the rate of inactivation of the channel while the tail may play a role in modulation of channel activity and/or targeting of the channel to specific subcellular compartments.
The segment S4 is probably the voltage-sensor and is characterized by a series of positively charged amino acids at every third position.
SEQUENCE SIMILARITIES: Belongs to the potassium channel family. A (Shaker) (TC 1.A.1.2) subfamily. Kv1.2/KCNA2 sub-subfamily. [View classification]

Rapid and efficient axon remyelination aids in restoring strong electrochemical communication with end organs and in preventing axonal degeneration often observed in demyelinating neuropathies. The signals from axons that can trigger more effective remyelination in vivo are still being elucidated. Here we report the remarkable effect of delayed brief electrical nerve stimulation (ES; 1 hour @ 20 Hz 5 days post-demyelination) on ensuing reparative events in a focally demyelinated adult rat peripheral nerve. ES impacted many parameters underlying successful remyelination. It effected increased neurofilament expression and phosphorylation, both implicated in axon protection. ES increased expression of myelin basic protein (MBP) and promoted node of Ranvier re-organization, both of which coincided with the early reappearance of remyelinated axons, effects not observed at the same time points in non-stimulated demyelinated nerves. The improved ES-associated remyelination was accompanied by enhanced clearance of ED-1 positive macrophages and attenuation of glial fibrillary acidic protein expression in accompanying Schwann cells, suggesting a more rapid clearance of myelin debris and return of Schwann cells to a nonreactive myelinating state. These benefits of ES correlated with increased levels of brain derived neurotrophic factor (BDNF) in the acute demyelination zone, a key molecule in the initiation of the myelination program. In conclusion, the tremendous impact of delayed brief nerve stimulation on enhancement of the innate capacity of a focally demyelinated nerve to successfully remyelinate identifies manipulation of this axis as a novel therapeutic target for demyelinating pathologies.
