INTRODUCTION
CD5 is a suitable immunohistochemical marker for T-cells, though not as sensitive as CD3. Approximately 76% of T-cell neoplasms are reported to express CD5, and it is also observed in chronic lymphocytic leukemia, hairy cell leukemia, and mantle cell lymphoma cells. CD5 is commonly lost in cutaneous T-cell lymphoma, and its deficiency can be used as an indicator of malignancy in this condition. CD5’s absence in T cell acute lymphoblastic leukemia, though relatively rare, is linked with a poor prognosis. CD5 serves as a receptor in regulating T-cell proliferation.
DESCRIPTION
CD5 Human Recombinant produced in Sf9 Baculovirus cells is a single, glycosylated polypeptide chain containing 359 amino acids (25-372a.a.) and having a molecular mass of 40kDa (Molecular size on SDS-PAGE will appear at approximately 40-57 kDa). CD5 is expressed with a 6 amino acids His tag at C-Terminus and purified by proprietary chromatographic techniques.
