Abstract
The recombinant bovine growth hormone (rbST) is used to increase lactating performances of dairy cows. Administration of rbST is banned in the European Union; nevertheless, its use is probable. Until now, efficient analytical strategies to detect such practice are based on the direct detection by mass spectrometry of the presence of rbST in biological fluids, which suits for confirmatory purposes. Current screening strategies do not offer satisfactory performances; therefore, alternative screening strategies are required. The aim of the present work is to develop and validate an ELISA to measure the production of specific antibodies upon rbST in bovine sera. In this immunoassay, rbST is absorbed onto microtiter plate. After specific purification of the antibodies in serum, samples are analysed and the presence of antibodies anti-rbST is detected by Protein G peroxidase conjugate and 2-2'-azino di-ethyl benz-thiazoline-6-sulphonic acid (ABTS). The mean reproducibility of the OD (λ=405 nm) measurement was calculated with a CV of 13%. The intra- and inter-assay CVs ranged from 0.79% to 7.91% and from 2.69% to 20% respectively. The test presents cross-reaction with other growth hormones such as the recombinant equine (reST) and porcine (pST) (100% and 80% respectively). The specificity of the test toward rbST anabolic treatment was confirmed through the analysis of sera samples collected on animals administered with other anabolic compounds (steroids). The performances of the present anti-rbST ELISA proves its efficiency as a new screening tool to highlight illegal administration of rbST in cattle up to at least 3 weeks after treatment.

Abstract
Somatotropins, which are used in cattle for growth and lactating performances, are difficult to reliably detect because no direct method exists. Reversed-phase high-performance liquid chromatography (RP-HLC) coupled to electrospray ionization quadrupole mass spectrometry (ESI/MS) has been developed to separate and characterize the N-terminal peptides resulting from tryptic cleavage of natural and recombinant growth hormones from different species (bovine, porcine, and human) and suppliers. Conditions for tryptic digestion were optimized. This technique was found to be optimal to cleave efficiently the N-terminal peptide of the proteins without releasing too much noise from the matrix. Characterization of the peptides through ESI(+)-MS allowed natural and recombinant growth hormones from bovine and porcine species with N-terminal amino acid sequences differing from one amino acid residue to be discriminated. However, the studied human growth hormones had similar primary sequences that did not permit any discrimination between recombinant and natural forms, thus confirming the known identity of these hormones. Protein digestions with pepsin and chymotrypsin were also compared but were not conclusive due to the too small N-terminal peptides released after proteolysis.

Abstract
An isocratic reversed-phase high-performance liquid chromatography (RP-HPLC) method for the determination of human growth hormone (hGH) directly in osmotic shock fluids is described. This methodology allows an initial rapid evaluation of the quality and quantity of hGH being secreted in the bacterial periplasmic space right after, or even during fermentation. Considering that RP-HPLC does not identify size isomers, these were determined via a parallel run of the same osmotic shock fluid on high-performance size-exclusion chromatography, coupled with radioimmunoassay, of the eluted fractions. The methodology provides a complete picture, within 24 h from the beginning of the fermentation process, of the recombinant protein being produced with respect to its activity, identity, yield, and hGH-related contaminants. These latter include sulfoxide and desamido derivatives, dimer and high-molecular-mass forms.

Abstract
Growth hormone (GH) is a polipeptide that controls the differentiation, growth and metabolism of many cell types, and is secreted from the hypophysis of all vertebrate species tested so far. Despite the overlapping evolutionary, structural, immunological and biological properties, it is well-known that GHs from distinct mammalian species have significant species-specific characteristics. The main purpose of this review is to highlight bovine GH (bGH) structural features related to its species-specific properties. Novel interest in bGH is also aroused by the advent of biotechnological methods for production of recombinant proteins. In fact recombinant bGH will have a great importance in veterinary medicine research and as a 'high tech' drug that needs to be monitored in zootechnical productions.
