Abstract

A single chain variable fragment (scFv), the smallest unit of functional recombinant antibody, is an attractive format of recombinant antibodies for various applications due to its small fragment and possibility of genetic engineering. Hybridoma clone 3A3 secreting anti-paclitaxel monoclonal antibody was used to construct genes encoding its variable domains of heavy (VH) and light (VL) chains. The VH and VL domains were linked to be the PT-scFv3A3 using flexible peptide linker in a format of VH-(GGGGS)5-VL. The PT-scFv3A3 was primarily expressed using the pET28a(+) vector in the Escherichia coli system, and was then further expressed by using the Bombyx mori nucleopolyhedrovirus (BmNPV) bacmid DNA system. Interestingly, the reactivity of PT-scFv3A3 expressed in the hemolymph of B. mori using the BmNPV bacmid DNA system was much higher than that expressed in the E. coli system. Using indirect competitive enzyme-linked immunosorbent assay (icELISA), the PT-scFv3A3 (B. mori) reacted not only with immobilized paclitaxel, but also with free paclitaxel in a concentration-dependent manner, with the linear range of free paclitaxel between 0.156 and 5.00 µg/ml. The PT-scFv3A3 (B. mori) exhibited less cross-reactivity (%) than its parental MAb clone 3A3 against paclitaxel-related compounds, including docetaxel (31.1 %), 7-xylosyltaxol (22.1 %), baccatin III (<0.68 %), 10-deacetylbaccatin III (<0.68 %), 1-hydroxybaccatin I (<0.68 %), and 1-acetoxy-5-deacetylbaccatin I (<0.68 %). With the exception of cephalomannine, the cross-reactivity was slightly increased to 8.50 %. The BmNPV bacmid DNA system was a highly efficient expression system of active PT-scFv3A3, which is applicable for PT-scFv3A3-based immunoassay of paclitaxel. In addition, the PT-scFv3A3 can be applied to evaluate its neutralizing property of paclitaxel or docetaxel toxicity.
