thymocytes from AKR/J (Thy 1.1) mice.

General description

Thymus cell antigen 1 (Thy 1.1) is a glycosylphosphatidyl-anchored protein. It belongs to the of the immunoglobulin superfamily. Thy 1.1 is expressed in stem cells, T-cells and neurons.

Physical form

Solution in 0.1 M phosphate buffered saline, pH 7.4, containing 15 mM sodium azide.


Recognizes Thy 1.1 bearing cells and is less than 5% cross-reactive with Thy 1.2 bearing cells. Titer is 1:20,000 as determined by in vitro cytotoxicity against AKR/J thymocytes.

Biochem/physiol Actions

Studies have shown that mice lacking the protein thymus cell antigen 1 (Thy 1.1) have an increased number of fibroblasts. It suppresses proliferation and enhances apoptosis in dermal fibroblasts, thereby modulating cell growth. This is carried out by regulating the action of β3 integrin.
