Abstract

Erythropoietin (EPO) is a glycoprotein hormone consists of 165 amino acids and has molecular mass of 30,400 Daltons. The large quantities of these hormone required to satisfy clinical demand are currently met by recombinant expression in mammalian cell, namely chinese hamster ovary (CHO). Pichia pastoris has become popular yeast based protein production systems to substitute mammalian expression systems. P. pastoris is capable to use methanol as sole carbon and energy source. In this study, recombinant human EPO (rhEPO) protein obtained by expressing the hEPO gene in methylotropic yeast P. pastoris, strain X33. The present work was carried out to study the optimal methanol concentration for induction and the incubation time to obtain rhEPO protein. To perform this study, the transformed P. pastoris was induced with various concentrations of methanol (0%, 0.5%, 1%, 2.5%, 5%, 10%, and 20%) and incubation times (0 hours, 24 hours, 48 hours, 72 hours, 96 hours, 120 hours, and 144 hours). The results demonstrate that the highest protein expression level occurred at concentration of 2.5% methanol induction, while the optimal incubation time was at 48 hrs.

Abstract

This study aims to explore the factors that influence impulse buying behavior on social commerce platforms caused by review quality, source credibility, and observational lierning which are mediated by positive effects. The population of this study is consumers on social commerce platforms. A total sample of 318 respondents. This research method is path analysis with analysis tools using the statistical software AMOS 24. This research found that review quality and source credibility had no effect on the positive effect, but observational lierning had a significant effect on the positive effect. The results of this research also found that review quality, source credibility, and positive effect affected impulse buying behavior, but observational lierning had no significant effect on impulse buying behavior. Furthermore, the positive effect can mediate the relationship between observational lierning and impulse buying behavior, but cannot mediate between review quality, and source credibility on impulse buying behavior. Marketers to increase impulsive buying behavior must create a positive effect on consumers and must also pay attention to review quality, source credibility, and observational lierning because these three things can increase impulsive buying behavior. So that should be the full attention of the company. The results of this study have a novelty that can be used to extend theoretical research. Research with this new research model also reveals the understanding that social interaction can motivate impulsive buying behavior. Meanwhile, this research also discusses the effects of mediating variables.
