Gene Information

human ... KCNH2(3757)

Specificity

Recognizes HERG (hKv11.1, Voltage gated K+ channel subfamily H member 2, KCNH2, ether-a-go-go related channel). The antibody recognizes the HERG1b splice variant but not splice variants HERG1-3 or HERG-4. The immunogen shares similiarity with rat erg2 (22/54) and rat erg3 (21/54).

Immunogen

Epitope: C-terminus
GST fusion protein corresponding to amino acids 1106-1159 of human erg1 (HERG) (Accession number Q12809).

Application

Anti-Potassium Channel HERG Antibody, C-terminus is an antibody against Potassium Channel HERG for use in IC, IP & WB.
Research Category
Neuroscience
Research Sub Category
Ion Channels & Transporters
Western blot: 1:200-400 using ECL on HERG transfected HEK293 cells.

Immunocytochemistry

Immunoprecipitation

Dilutions should be made using a carrier protein such as BSA (1-3%)

Optimal working dilutions must be determined by the end user.

Target description

127 kDa

Physical form

Affinity Purified immunoglobulin. Lyophilized from phosphate buffered saline, pH 7.4, containing 1% BSA, and 0.025% sodium azide as a preservative. Reconstitute with 200 μL of sterile deionized water. Centrifuge antibody preparation before use (10,000 xg for 5 min).
ImmunoAffinity Purified

Storage and Stability

Maintain lyophilized material at -20°C for up to 12 months after date of receipt. After reconstitution maintain at -20°C in undiluted aliquots for up to 6 months. Avoid repeated freeze/thaw cycles.

Analysis Note

Control
CONTROL ANTIGEN: Included free of charge with the antibody is 120 μg of fusion protein (35 kD). The stock solution of the antigen can be made up using 100 μL of PBS. For negative control, preincubate 3 μg of fusion protein with 1 μg of antibody for one hour at room temperature. For positive control, use 20 ng of fusion protein per lane. Optimal concentrations must be determined by the end user.

Other Notes

Concentration: Please refer to the Certificate of Analysis for the lot-specific concentration.

Heart failure (HF) is characterized by marked prolongation of action potential duration and reduction in cellular repolarization reserve. These changes are caused in large part by HF-induced K(+) current downregulation. Molecular mechanisms underlying these changes remain unclear. We determined whether
