CloneID: OX-58
Antigen Long Description: This antibody was prepared by immunizing BALB/c mice with rat thymocyte leukosialin and thymocytes.
Buffer Composition: PBS only.
Chimeric Use Statement: This chimeric rat antibody was made using the variable domain sequences of the original Mouse IgG2b format, for improved compatibility with existing reagents, assays and techniques.
Uniprot Accession No.: P13838
Specificity Statement: This antibody recognises rat leukosialin, a major cell-surface sialoglycoprotein of thymocytes and T lymphocytes. It is also expressed on neutrophils, bone marrow stem cells and B-lineage cells after activation. The specificity of the leukosialin epitope is largely determined by linear protein sequence, as indicated by the reaction of this antibody with the extracellular domain of leukosialian expressed in an unglycosylated form in E. coli. However, the sensitivity of this antibody to neuraminidase treatment of leukosialin indicates that glycosylation can modify epitope conformation or flexibility.
Application Notes (Clone): This antibody binds to rat leukosialin, and can be used to label thymocytes and T lymphocytes in the lymph node cell population in flow cytometry analysis. This antibody has also been used, along with other anti-CD43 MABs, in a Western blot analysis to localize leukosialin epitopes.
