The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
Use a concentration of 5 µg/ml.
Use a concentration of 1 µg/ml. Detects a band of approximately 81 kDa (predicted molecular weight: 81 kDa). Good results were obtained when blocked with 5% non-fat dry milk in 0.05% PBS-T.
Involved in regulating cell migration through association with the actin cytoskeleton. Has an essential role in the maintenance of Z line and sarcomere integrity.
Abundantly expressed in heart and skeletal muscle, and at lower levels in placenta, lung, liver and pancreas. Also expressed in HeLa S3 and Molt-4 cells.
Involvement in disease
Defects in NEXN are the cause of cardiomyopathy dilated type 1CC (CMD1CC) [MIM:613122]. A disorder characterized by ventricular dilation and impaired systolic function, resulting in congestive heart failure and arrhythmia. Patients are at risk of premature death. Defects in NEXN are the cause of cardiomyopathy familial hypertrophic type 20 (CMH20) [MIM:613876]. CMH20 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.
Contains 1 Ig-like (immunoglobulin-like) domain.
Cytoplasm > cytoskeleton. Cell junction > adherens junction. Cytoplasm > myofibril > sarcomere > Z line. Localizes to the cell-matrix AJ. Not found at the cell-cell AJ.
ICC/IF image of ab83746 stained HeLa cells. The cells were 100% methanol fixed (5 min) and then incubated in 1%BSA / 10% normal goat serum / 0.3M glycine in 0.1% PBS-Tween for 1h to permeabilise the cells and block non-specific protein-protein interactions. The cells were then incubated with the antibody (ab83746, 1µg/ml) overnight at +4°C. The secondary antibody (green) was ab96899 Dylight 488 goat anti-rabbir IgG (H+L) used at a 1/250 dilution for 1h. Alexa Fluor® 594 WGA was used to label plasma membranes (red) at a 1/200 dilution for 1h. DAPI was used to stain the cell nuclei (blue) at a concentration of 1.43µM.
