AbstractHomoharringtonine (HHT), also known as omacetaxine, is a natural compound found in the genus Cephalotaxus and is a promising pharmaceutical drug used for the treatment of chronic or accelerated phase chronic myeloid leukemia. As a tool for the quantitative determination of HHT, a specific monoclonal antibody against HHT (MAb 6A1) was generated by conjugates prepared via sodium periodate-mediated oxidation. The developed indirect competitive enzyme-linked immunosorbent assay (icELISA) using MAb 6A1 was found to be highly specific and sensitive with a limit of detection for HHT of 48.8 ng/mL. Validation assays to evaluate precision and accuracy of the method were conducted by the use of intra- and inter-assay analysis, recovery test, and comparison analysis between the amounts of HHT determined by ELISA and high-performance liquid chromatography. These results revealed that the established icELISA using MAb 6A1 is specific, sensitive, and reliable enough to be applied to the qualitative analysis for HHT. Furthermore, the results of this study support the usefulness of sodium periodate as a reagent for the conjugation between Cephalotaxus alkaloids and proteins for producing specific antibodies.

Abstract This is an enzyme-linked immunosorbent assay (ELISA) for determining chromogranin A (CGA) with use of a monoclonal antibody. CGA was isolated from bovine chromaffin granules. The analytical ELISA procedure for bovine CGA was developed and optimized. Typical standard curves ranged from 500 pg to 500 ng of CGA. We then studied human plasma CGA-immunoreactivity as measured by this assay. The curve for dilutions of human plasma paralleled the standard curve for bovine CGA. The intra-assay coefficient of variation for determination of human plasma CGA was 4.56%, indicating that reliable determinations can be performed for human plasma. However, further study revealed the presence of two CGA-immunoreactive substances in human plasma, one of which corresponds to the native CGA. The nature of the second immunoreactive substance still remains unknown. Nevertheless the measured CGA concentrations (ranging from 0.19 to 0.35 mg/L) in plasma are comparable with previously reported values.
