CLONE: XIX.8

ISOTYPE: IgG2a

SOURCE: Mouse ascitic fluid

PURIFICATION Ion exchange chromatography following ammonium sulphate precipitation.

SPECIFICITY: 50Kd MW lymphocyte surface antigen identified by monoclonal antibodies belonging to the CD2 cluster. The antigen is expressed on all peripheral blood T lymphocytes, majority of thymocytes and malignant cells of T cell origin, including T- ALL cells. Normal B lymphocytes, monocytes or granulocytes do not express surface CD2 antigen. Common ALL cells do not express CD2 antigen.

The antigen identified by CD2 type monoclonal antibodies has been characterised as the receptor for sheep erythrocytes and pre-treatment of lymphocytes with CD2 monoclonal antibodies inhibits E rosette formation. The antigen also functions as the receptor for the CD 58 antigen (LFA-3).

Antigen distribution: T-cells (E+)                          100%

                               Thymocytes                          95 � 3%

                               Peripheral blood lymphocytes 82 � 5%

                               NK-cells (CD16+)                50 � 10%

                               Granulocytes                          < 1%

                               Monocytes                             < 1%

                               B-cells (E-)                            < 1%

APPLICATIONS: * Identification of T lymphocytes by indirect immunofluorescence staining

                              * Leukaemia and lymphoma phenotyping

                              * Identification of normal and malignant T lymphocytes in cryostat sections of    frozen tissue

                              * Immunoprecipitation of the CD2 antigen

                              * Isolation or removal of T lymphocytes by FACS or panning techniques

PRESENTATION: Each monoclonal is delivered in a sealed vial at a concentration of not less than 200�g/2ml in phosphate buffered saline containing 10mM sodium azide and 1mg/ml of bovine serum albumin. We recommend that each laboratory determine an optimum working titre for use in its particular application.

STORAGE: Purified monoclonal antibodies are generally stable for long periods at 4oC. However repeated warming to room temperature and re-cooling may result in a loss of activity and hence effective working titre. It is recommended that monoclonal antibodies are aliquotted upon receipt and then stored at -20C. After thawing they should then be used as a stock solution for up to 30 days. Dilute working solutions are best prepared on the day of use.

SPECIFICITY : The antibody reacts with a 50 kDa lymphocyte surface molecule identified by monoclonal antibodies belonging to the CD2 cluster. The antigen is also known as sheep erythrocyte receptor and functions as a receptor for the CD58 antigen (LFA-3) through its NH2 terminal domain. The antigen is expressed on all peripheral blood T lymphocytes, the majority of thymocytes and malignant cells of T cell origin, including T ALL cells. Normal B lymphocytes, monocytes or granulocytes do not express surface CD2 antigen. Common ALL cells do not express CD2 antigen.
