antibody anti-Thy1 antibody 2013-03-12T18:06:13Z An immunoglobulin molecule having a specific amino acid sequence that gives it the ability to adhere to and interact only with Thy1, i.e. Thymocyte antigen 1, and molecules containing structures similar to that antigen. Thy1, also known as CD90, is a 25-37 kDa, heavily N-glycosylated, glycophosphatidylinositol (GPI) anchored, conserved cell surface protein with a single V-like immunoglobulin domain, originally discovered as a thymocyte antigen and now known to be the smallest member of the immunoglobulin superfamily of proteins.
