Optimal protein expression
WebJun 20, 2024 · For optimal protein expression, ExpiSf9 cells in suspension culture at the time of infection should be at a passage number of less than 30. 5. I obtained good expression in small scale but lost expression in large scale. Tip: You may need to adjust some of your parameters slightly at larger scale. WebJun 19, 2024 · Promoter. Promoter is a very critical region in plasmid vectors, used for the expression of heterologous proteins. Promoter is a stretch of DNA that is involved in the initiation of transcription of a gene and is located upstream of the transcription initiation site of gene. Promoters are normally 100–1000 base pairs in size.
