Description

In this work, we aimed to test the feasibility of using the HiBiT assay for assessing protein expression in two microbial hosts: Escherichia coli and Pichia pastoris. These hosts represent distinct expression systems, bacterial and yeast, that serve as an ideal starting point to evaluate cross-organismal assay performance. The goal of this study is to determine whether a workflow involving a HiBiT-tagged approach to measuring soluble protein can reliably quantify expression levels across these systems and provide the necessary scalability and robustness required for broader implementation.
