Polyclonal antisera

The aim of this study was to determine the prevalence of Dal, and DEA 1, 4, 7 blood types, in a population of canine blood donors from Italy and Spain. Three hundred and twenty blood donor dogs receiving an annual health evaluation were included in the study. DEA 1 blood type was determined using an immunochromatographic strip technique while Dal, DEA 4 and 7 blood types were determined with polyclonal antisera using agglutination on gel columns.

Purified viral protein was obtained from Potato virus Y (PVY) pure culture maintained on potato (Solanum tuberosum L.) plants. The average concentration of the purified materials was found to be 153.1 ng/µl. PVY purified virus preparation was used for immunizing rabbit for production of polyclonal antisera against the virus. Good quality antisera were collected one week post boosters (AS4b, AS5b, AS6b and AS7b) and the IgG fractions were separated through ammonium sulphate precipitation.

Dehydration-responsive element-binding (DREB) proteins play a critical role in the plant’s droughttolerance mechanism despite their presence in minor amounts in the cell. In this study, a maize-derived transcription factor protein, ZmDREB2.7, was overexpressed in the Escherichia coli strain Rosetta 1. The interested gene conjugating with the thioredoxin gene (TrxA) and his6 tag in the pET-32a vector encoded a 55.7 kDa fusion protein. The optimum condition for inducing the thioredoxin-his6 -ZmDREB2.7 expression was five hours of induction with 0.05 mM IPTG at 300 C. The Tris-HCl 20 mM pH 8.
