Specificity / Sensitivity

Thy1 Antibody recognizes endogenous levels of total Thy1 protein.

Source / Purification

Polyclonal antibodies are produced by immunizing animals with a synthetic peptide corresponding to residues surrounding Thr66 of human Thy1 protein. Antibodies are purified by protein A and peptide affinity chromatography.

The Thy1 cell surface antigen is a GPI-anchored, developmentally regulated protein involved in signaling cascades that mediate neurite outgrowth, T cell activation, tumor suppression, apoptosis, and fibrosis (1). Thy1 is highly expressed on the surface of adult neurons and is thought to play a role in modulating adhesive and migratory events, such as neurite extension (1,2). Decreased Thy1 mRNA and protein expression is associated with the development of epithelial ovarian cancer, suggesting a role as a putative tumor suppressor gene of human ovarian cancer (3,4). Research studies indicate that Thy1 knockout mice have impaired cutaneous immune responses and abnormal retinal development (5,6). Thy1 is epigenetically regulated or deregulated in some disease states, such as pulmonary fibrosis. The potentially reversible hypermethylation of the Thy1 promoter offers the possibility of novel therapeutic options in this disease (7).
