Product Name :
Rabbit anti Rat Kv3.1b Potassium Channel
Description :
| Isotype IgG | Product Type Polyclonal Antibody | Units 100 µg | Host Rabbit | Species Reactivity Human Mouse Rat | Application Western Blotting
Background :
Rabbits were immunized with a synthetic peptide derived from the rat Kv3.1b potassium channel conjugated to KLH
Source :
The Kv3.1b potassium channel is a voltage-gated channel protein which belongs to the delayed rectifier class and to the Shaw potassium channel subfamily. Potassium channels are mainly found in plasma membranes but are not generally distributed over the cell surface. Potassium channels catalyze the rapid permeation of potassium ions while rejecting biologically abundant potential competitors such as sodium, calcium and magnesium. Ion selectivity and high through put rate of potassium channels is accomplished by precise co-ordination of dehydrated potassium by the protein and multiple ion occupancy within the permeation pathway. All potassium channels carry out the formation of a transmembrane leak specific for potassium ions. Since cells almost universally maintain cytoplasmic potassium concentrations higher than those extracellularly, the opening of a potassium channel implies a negative ongoing change in electrical voltage across the cell membrane. This may result in termination of the action potential of electrically excitable cells including nerve, muscle and pancreatic beta cells. In nonÐexcitable cells, potassium channels play important roles in the cellular potassium recycling required for electrolyte balance effected by the renal epithelium. <
Product :
Provided as solution in phosphate buffered saline with 0.08% sodium azide Product Form: Unconjugated Purification Method: Ammonium Sulfate Precipitation Concentration: See vial for concentration
Specificity :
Rabbits were immunized with a synthetic peptide comprising residues 567–585 of the intracellular C-terminus of the rat Kv3.1b isoform. In rat the two major splice isoforms Kv3.1a and Kv3.1b differ at the cytoplasmic C-terminal domain, which is longer in the Kv3.1b isoform. The peptide for immunization of the rabbits was therefore chosen to recognize this additional sequence in the Kv3.1b isoform.
