Background Information

MYH6 encodes the alpha-cardiac myosin heavy chain (aMHC) which is a major contractile protein exclusively expressed in the myocardium of the heart. Expression of MYH6 is down-regulated in cardiac myopathy and failing hearts. Defects in MYH6 lead to congenital heart disease (CHD), and a spectrum of phenotypes ranging from hypertrophic cardiomyopathy (HCM) and dilated cardiomyopathy (DCM). (15737621, 20656787)

MYH6 Antibody Western Blot validation (1:8000 dilution) in Mouse heart (Cat no:22281-1-AP)

Jane (Verified Customer) (02-03-2022)

one specific band around 230kDa, however, the band was not very sharp. Probably will help if run at a lower percentage gel.

  • Applications: Western Blot
  • Primary Antibody Dilution: 1:1000
  • Cell Tissue Type: Heart tissue

Jing (Verified Customer) (02-08-2021)

good antibody, clear sigle band around 260KD.

  • Applications: Western Blot
