Abstract:
This study were examined the efficiency of Western Blot Transfer System between Wet Tank Blotting Systems version of Mini Trans-Blot® Cell and Semi-dry version of Trans-Blot® Turbo ™ Transfer System. The vitellin protein levels examination in the female domesticated giant tiger shrimp (Penaeus monodon) brood stock were divided into 6 treatments; shrimp were fed with diets without hormone; N=12), eyestalk-ablation shrimp were fed with diets without hormone (N=12), shrimp were fed with diets enhanced with 17-estradiol hormone at 10, 50, 100 and 500 mg/kg (N=16, 16, 16 and 8) respectively. The experiment have been performed for a period of 60 days and the samples were collected at day 35 and 60 for determinations of ovary, hepatopancreas and hemolymph. The results showed that the average of GSI of eyestalk-ablation shrimp were fed with diets without hormone (1.78±0.65%) at day 35 was significantly higher than other groups (p<0.05). While, there was no significant different of the GSI in each experimental groups (p>0.05) at day 60. The protein levels in hemolymph were (16.07314.55 mg/ml) higher than ovary (16.07314.55 mg/ml) and hepatopancreas (0.928.79 mg/ml). Moreover, analysis total protein patterns by 10% polyacrylamide gel SDS-PAGE) in ovaries, hepatopancreas and hemolymph were found that the protein bands could be seen with 20 bands. Studying the size of vitellin protein were analyzed by Western Blot method through using antibodies that specific to vitellin proteins of black tiger shrimp. The results at day 35 and 60 were found that the vitellin proteins sizes content were 13 and 15 respectively, which could be found the similarity of protein size were 200, 157, 130, 104, 74, 63, 58, 38 and 34 kDa. In addition, the transferring proteins of the semi-dry appeared on performed obviously protein bands more than those of appeared by wet tanks. The comparison of protein vitellin levels in the giant tiger shrimp cultured for 35 and 60 days with both methods, the results showed that the appearance and non-appearance of protein bands similarity were 89.32% and 94.44% respectively whereas the appearance of different protein bands were 10.68% and 5.56% respectively. However, the both methods appearance of protein bands similarity were 50% while Semi-dry analysis was appeared more protein bands than wet tanks at 46.67% and the wet tank analysis was appeared more protein bands than semi-dry at 3.33%.
