The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
1/20 - 1/50. Perform heat mediated antigen retrieval with citrate buffer pH 6 before commencing with IHC staining protocol. Use buffer at pH 6 for antigen retrieval.
Use a concentration of 1 - 4 µg/ml. The following steps are recommended prior to antibody incubation: cells fixation in ice cold 4% paraformaldehyde pH 7.2-7.3, followed by permeabilization with 0.1% Triton X-100 in PBS for 3x5 minutes.
FunctionMay be involved in intracellular trafficking of the muscle cell when in the cytoplasm, whereas entering the nucleus, may be involved in the regulation of muscle specific genes. May play a role in the control of tumor development and progression; restored MYO18B expression in lung cancer cells suppresses anchorage-independent growth.
Tissue specificitySelectively expressed in cardiac and skeletal muscles. Weakly expressed in testis, pancreas, placenta, prostate, lung and thymus.
Sequence similaritiesContains 1 IQ domain. Contains 1 myosin head-like domain.
Developmental stageReaches an expression peak in the third day after induction and remains at similar level during successive myotubule maturation.
Cellular localizationCytoplasm. Nucleus. Cytoplasm > myofibril > sarcomere. Punctate pattern in undifferentiated myoblasts. Nuclear, on primary cardiomyocytes and adult muscle. A partial sarcomeric location was found in some cardiomyocytes.
