Anti-Titin antibody, Mouse monoclonal

Monoclonal Anti-Titin (mouse IgG2b isotype) is derived from the hybridoma produced by the fusion of mouse myeloma cells and splenocytes from an immunized mouse. It is a flexible, filamentous constituent of striated muscle that is thought to give rise to an elastic filament component underlying the myofibrillar organization.

Titin (TTN), also known as connectin, is encoded by the gene mapped to human chromosome 2q31.2. TTN is a giant elastic protein expressed in striated and smooth muscles of vertebrates. The encoded protein contains up to 300 immunoglobulin-like and fibronectin type-3-like (FN3) domains.

Monoclonal Anti-Titin antibody produced in mouse has been used in following studies.

• western blotting
• antibody staining
• immunofluorescence microscopy
• immunohistochemistry

Monoclonal Anti-Titin can be used for study of the elastic filaments within sarcomeric structures. It is also useful as a differentiation marker in the separation of rhabdomyosarcomas from other muscle tumors.

The antibody localizes titin (connectin) in skeletal and heart muscle of a wide variety of species from cold-blooded vertebrates to human. The antibody does not cross-react with nebulin. Likewise, it does not react with smooth muscle, non-muscle tissues, or cultured cells.

Titin (TTN) helps in maintaining sarcomeric structural integrity by interacting with many other myofibrillar and cytoskeletal proteins. Additionally, it is also involved in developing the passive elastic force in muscle. Genetic variations in the gene has been associated with the development of dilated cardiomyopathy (DCM).
