synthetic peptide SPGMIYSTRYGSPKR(C), corresponding to amino acid residues 20-34 of rat KVβ2.

Target description

KVβ2, as well as the other KVβ subunits can bind to all the members of the large KV1.x (Shaker) channel subfamily. However, recent evidence suggests that it can also bind to members of the KV4.x subfamily. KVβ2 is the most abundant β subunit in the brain where it couples with all the KV1.x subunits, but the protein is also expressed in peripheral tissues including heart, lung and cells of hematopoietic origin such as T cells where it couples with KV1.3, the dominant voltage-dependent K+ channel in these cells.

Physical form

Lyophilized powder from phosphate buffered saline (PBS), pH 7.4, containing 1% BSA and 0.25% sodium azide.


Reconstitute the lyophilized vial with 50μL or 200 μL deionized water, depending on package size. Further dilutions should be made using a carrier protein such as BSA (1-3%).
