  • FunctionRegulatory light chain of myosin. Does not bind calcium.
  • Involvement in diseaseDefects in MYL3 are the cause of cardiomyopathy familial hypertrophic type 8 (CMH8) [MIM:608751]. Familial hypertrophic cardiomyopathy is a hereditary heart disorder characterized by ventricular hypertrophy, which is usually asymmetric and often involves the interventricular septum. The symptoms include dyspnea, syncope, collapse, palpitations, and chest pain. They can be readily provoked by exercise. The disorder has inter- and intrafamilial variability ranging from benign to malignant forms with high risk of cardiac failure and sudden cardiac death. CMH8 inheritance can be autosomal dominant or recessive.
    Defects in MYL3 are the cause of cardiomyopathy familial hypertrophic with mid-left ventricular chamber type 1 (MVC1) [MIM:608751]. MVC1 is a very rare variant of familial hypertrophic cardiomyopathy, characterized by mid-left ventricular chamber thickening.
  • Sequence similaritiesContains 3 EF-hand domains.

  • Procedure:
    Coat tube with MLM544
    Wash 2 times
    Block with BSA-PBS
    Add sample or standard (porcine cardiac myosin light chain I)
    Add 125I-labeled MLM508
    Incubate for 18 (12-24) h at 20 (10-20) °C
    Wash 2 times
    Measure radioactivity.

  • IHC image of ab678 staining in human heart muscle formalin fixed paraffin embedded tissue section, performed on a Leica BondTM system using the standard protocol F. The section was pre-treated using heat mediated antigen retrieval with sodium citrate buffer (pH6, epitope retrieval solution 1) for 20 mins. The section was then incubated with ab678, 1µg/ml, for 15 mins at room temperature and detected using an HRP conjugated compact polymer system. DAB was used as the chromogen. The section was then counterstained with haematoxylin and mounted with DPX.

    For other IHC staining systems (automated and non-automated) customers should optimize variable parameters such as antigen retrieval conditions, primary antibody concentration and antibody incubation times.

Thank you for your enquiry. This antibody can react to the rat protein (myosin light chain I) almost equally to human and porcine protein in ELISA. If you have any additional questions, please contact us again.

Thank you for your email. For ab676, the concentration of cardiac MLI is 1 microgram/ml in PBS containing 1% BSA, 0.1% proclin. Purified material (> 90% purity) was diluted with the above buffer. For ab678, is has been tested in ELISA and does cross-re...
