Abstract

The long-term objective of this study was to produce STAT synthetic protein in chicken during growth period resulting from the increase of growth hormone (GH) as growth promoter. This study used ten male chicken Lohman from PT. Multibreeder Indonesia. The chicken were kept within batteried cage, with a capacity of one chicken in each cage. The chickens were fed twice a day, at 6 a.m. and 6 p.m. with the amount of feed 10% less than standard. On day 21 the chicken were slaughtered to obtain the samples, i.e., adipose, liver and muscles for the following examinations (1) isolation of STAT-3 signaling protein from adipose, liver and muscles of the chicken, (2) analysis of STAT-3 signaling protein using SDS-PAGE method, and (3) identification of STAT-3 signaling protein using Western blot method by means of protein detection using electrophoresis with polyacrylamide gels. Results of examination on protein in hepatic, muscle and adipose of chickens in growth period revealed that STAT protein was positively present in those tissues. This finding was followed-up with SDS-PAGE examination, from which we found the presence of protein band between the markers of 116 kDa and 14.4 kDa. The protein band was supposedly the STAT-3 protein. To prove that protein band formed was the STAT-3, Western blot examination was conducted using rabbit polyclonal antibody STAT-3. The result showed the formation of the protein band, indicating the presence of reaction between antigen (STAT-3 protein) and STAT-3 protein antibody. In conclusion, STAT-3 protein is present in hepatic, muscular, and adipose tissues, with molecular weight of 59.4 kDa.
