Pichia pastoris cell-free protein synthesis kit

Zhongshuo Bio's Pichia pastoris cell-free protein synthesis kit uses the AOX1 promoter to drive transcription of the target gene in vitro, completes mRNA synthesis through the yeast's endogenous RNA polymerase II, and relies on ribosomes and translation factors retained in the lysate to achieve protein expression. The system requires no addition of exogenous RNA polymerase and can achieve efficient protein synthesis within 3 hours; it ...
