Datasheet Extract

Glycoproteins from the RL-5 T-cell line. Spleen cells from immunised BALB/c mice were fused with cells of the P3.X63.Ag8-U1 mouse myeloma cell line.
Application Flow Cytometry.
Immunohistochemistry on frozen sections.
Background CD43 is one of the major glycoproteins of thymocytes and T lymphocytes, it plays a role in the physicochemical properties of the T cell surface and in lectin binding. CD43 presents carbohydrate ligands to selectins. It has an extended rodlike structure that could protrude above the glycocalyx of the cell and allow multiple glycan chains to be accessible for binding. The antigen is a counter receptor for SN/Siglec1. During T cell activation CD43 is actively removed from the T cell antigen presenting cell contact site suggesting a negative regulatory role in adaptive immune response.
CD43 is expressed by the majority of leucocytes, with the exception of most B cells. However CD43 expression is seen in some cases of B cell lymphocytic lymphoma and centrocytic lymphoma.
Concentration 16.7 mg/ml

This antibody recognises all T cells by flow cytometry; monocytes and macrophages stain weakly. Good staining of TCell dependent areas in lymphoid tissue sections is observed. This antibody immunoprecipitates and immunoblots a 120kD protein from RL-5 cells and T lymphocytes. It is believed to recognise the homologue of Human CD43, Leukosialin. Clone L11/135 has been reported as being suitable for use in Western blotting.
