Recombinant monoclonal antibody to CD99. Manufactured using AbAb’s Recombinant Platform with variable regions (i.e. specificity) from the hybridoma 12E7.
UniProt Accession Number of Target Protein: P14209
Alternative Name(s) of Target: CD99 antigen; E2 antigen; Protein MIC2; T-cell surface glycoprotein E2; 12E7; MIC2; MIC2X; MIC2Y
Immunogen: The original antibody was generated by immunizing BALB/c mice intraperitoneally with glutaraldehyde-fixed human acute lymphocytic leukemia (ALL) cells obtained from peripheral blood of a child.
Specificity: This antibody binds human CD99. CD99 is involved in T-cell adhesion processes and in spontaneous rosette formation with erythrocytes. It plays a role in a late step of leukocyte extravasation helping leukocytes to overcome the endothelial basement membrane.
Application Notes: The original mouse IgG1 version of this antibody was used for the indirect immunofluorescence staining of a fixed bone marrow smear from a patient with T-cell leukemia. The binding specificity of this antibody towards CD99 was tested using radioimmunoassay (PMID: 316541). This antibody was able to identify 28 kDa component present on lymphocytes, red blood cells and platelets in a western blot assay (PMID: 2447875). This antibody was used in the immunocytochemical studies of Ewing's sarcoma and peripheral neuroectodermal tumour (PMID: 8314240). This antibody was also used in the immunohistochemical studies of formalin-fixed, paraffin-embedded lymphoblastic lymphoma (LyL)/acute lymphoblastic leukemia (ALL) samples collected from 24 patients (PMID: 9343323). This antibody was also used in a study relating to the cell surface expression MIC2 antigen on human leukocytes in bone marrow (BM), thymus, and peripheral blood (PB) using multiparameter flow cytometry and cell sorting (PMID: 7506950).
