Thy-1 Antibody (ER4) is a mouse monoclonal IgG2a antibody that detects Thy-1 in mouse and rat samples through applications such as western blotting (WB) and immunoprecipitation (IP). Thy-1, also known as CDw90, is a phosphatidyl-anchored cell surface glycoprotein that plays a crucial role in cell adhesion and signaling, particularly in hematopoietic stem cells. Thy-1 expression is vital for identifying specific subpopulations of cells within mixed colonies, especially when coexpressed with CD34, as Thy-1 marks a subset of putative hematopoietic, pleuripotent stem cells found in normal human bone marrow. Thy-1+ cells have been linked to significant immunological processes, including the regulation of autoreactivity following bone marrow transplants and the development of syngeneic graft versus host disease. Understanding Thy-1 function is essential for advancing therapeutic strategies in regenerative medicine and transplantation, as Thy-1 may influence stem cell behavior and interactions within the immune system. Anti-Thy-1 antibody (ER4) is an invaluable tool for researchers investigating these complex biological processes.

I bought the L form of this antibody, sc-81667 L for blocking (neutralization). How long can I store this at in the refridgerator?

Asked by: Randy McDonald
The L form of the antibody should be stored at -20°C. Once thawed, we recommend using as soon as possible, although it is usually stable for up to 2 weeks at 4 degrees.
