Detection of MYH7 by Western Blot. Western blot shows lysates of human heart (ventricle) tissue. PVDF membrane was probed with 0.5 µg/mL of Rabbit Anti-Human MYH7 Monoclonal Antibody (Catalog # MAB90961) followed by HRP-conjugated Anti-Rabbit IgG Secondary Antibody (Catalog # HAF008). A specific band was detected for MYH7 at approximately 230 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.
MYH7 in Human Cardiomyocytes. MYH7 was detected in immersion fixed BG01V human embryonic stem cells differentiated into cardiomyocytes using Rabbit Anti-Human MYH7 Monoclonal Antibody (Catalog # MAB90961) at 10 µg/mL for 3 hours at room temperature. Cells were stained using the NorthernLights™ 557-conjugated Anti-Rabbit IgG Secondary Antibody (red; Catalog # NL004) and counterstained with DAPI (blue). Specific staining was localized to cytoplasm. View our protocol for Fluorescent ICC Staining of Stem Cells on Coverslips.

MYH7 encodes the beta myosin heavy chain (MHC-beta ) which is a component of cardiac muscle myosin mainly expressed in the ventricle of fetal heart and represents the minority myosin in the adult heart. This is the 'slow form' of cardiac myosin as opposed to the 'fast form' (MYH6, aka MHC-alpha ) expressed more predominantely in the atria of the fetal heart and is the predominant myosin in the adult heart. The two isoforms of cardiac MHC alpha and beta display 93% homology but have significantly different enzymatic properties, with alpha having 150-300% the contractile velocity and 60-70% actin attachment time as that of beta. Several mutations in MYH7 have been associated with inherited cardiomyopathies paraspinal and proximal muscle atrophy. MYH7 is a 223 kDa protein composed of 1935 amino acids.
