WebFeb 1, 2024 · Here, we show that BL21-AI is able to precisely regulate protein production rates on a cellular level in an l-arabinose concentration-dependent manner and … WebFeb 27, 2024 · This seems to be the case for BL21-AI, where T7 RNA polymerase appears to be produced from the uninduced pBAD promoter at a lower rate than in BL21 (DE3) from the uninduced lacUV5 promoter. Indeed, some toxic target genes we have worked with were easier to establish and maintain in BL21-AI than in BL21 (DE3), although"
