Abstract An easy, sensitive, competitive indirect enzyme- linked immunosorbent assay (CI-ELISA) for specti nomycin in chicken plasma was developed. Preparation of a spectinomycin-bovine serum albumin conjugate in which the hapten is linked to the carrier protein through the C-4 position is described. Antibodies raised against antigens in rabbits had excellent specificity for spectinomycin, exhibiting a cross-reactivity of 44.0% with dihydrospectinomy-cin and 13.8% with tetrahydrospectinomycin. No cross-reactivity was observed with other antibiotics. The detection limit of the CI-ELISA was 2 ng/mL (equivalent into 40 ng/mL undiluted chicken plasma) spectinomycin. Known amounts (0.1-100 μg/mL) of spectinomycin were added to chicken plasma and then analyzed. Average recoveries were 97-110%. This procedure may be used without prior extraction of samples.

 Dalam pengembangan metoda analisis residu antibiotik pada produk pangan hewani secara immunokimia telah dilakukan sintesis imunogen kloramfenikol (CAP) dengan protein Bovine Serum Albumin (BSA) dan Keyhole Limpet Hemocyanin (KLH) dengan metoda konjugasi mixed anhidrad. Hasil sintesis digunakan untuk produksi antibodi.Antigen dan antibodi yang dihasilkan dijadikan prangkat analisis residu antibiotik dengan Competitive Enzyme Linked Immunosorbent Assay (ELISA kompetitif). Hasil penelitian menunjukkan bahwa metoda konjugasi mixed anhidrad pada preparasi imunogen dengan jumlah CAP yang terkonjugasi ke grup amino bebas dari molekul protein BSA (CAP-BSA) adalah 18 unit dan ke protein KLH (CAP-KLH) adalah 782 unit. Antibodi poliklonal CAP-BSA dan CAP-KLH yang diproduksi dengan rata-rata kandungan IgG CAP-BSA 2,07 mg/ml dan IgG CAP-KLH 2,21 mg/ml.

The development of polyclonal antibody-based enzyme-linked immunosorbent assays (ELISA) for the determination of individual isoflavones, i.e. daidzein, genistein and biochanin and their homologues, is presented in this work. Isoflavone conjugates with bovine serum albumin were used as immunogens, coupled at the position C 7 and C 4’ via a carboxy methyl spacer. The developed ELISAs are highly specific, I<sub>50</sub> values of the standard curves range between 0.3–1.2 ng/ml. The cross reactivities to other isoflavones are in acceptable range and the interference of non-isoflavonoid molecules is negligible. The immunoassays have been used for monitoring of changes in isoflavone levels in alimentary important plants, such as Medicago sativa, during germination; and during different vegetation stages of the Rutaceae family plants.

Toxicological Analysis

Monoclonal antibodies(MoAbs) very specific to diquat (DQ) were produced. An immunogen was synthesized by binding DQ to bovine serum albumin via a diazo-coupled derivative. BALB/c mice were immunized i.p. monthly with 0.25mg of the immunogen for five months. Their spleen cells were fused with P3U1 myeloma cells and hybridoma clones secreting MoAbs were obtained. Two MoAbs were selected and subtyped to be IgM and IgG3. The MoAbs recognized DQ but did not bind to paraquat and other analogues at all. A datum obtained from a clinical sample demonstrates that an enzyme-linked immunosorbent assay system using one of the MoAbs is useful in the practice of toxicological analysis.
