Protein Expression in Microbial Systems
Automating single-cell cloning of bacteria, yeast and other microorganisms
Paving the way for successful biopharmaceuticals
Production of recombinant proteins plays a major role in the life sciences, biotechnology and medicine, and enables the development and production of many successful biopharmaceuticals. While mammalian systems are the method of choice for monoclonal antibodies requiring human-like glycosylation, microbial expression systems such as bacteria or yeast are widely used for production of peptides or small to mid-size recombinant proteins such as antibody fragments.
Fast doubling times, high cell densities, and high productivities make organisms such as Escherichia coli or Saccharomyces cerevisiae useful microbial cell factories for drug development, synthetic biology or screening applications.
Single-cell isolation is a key step in the development of stable expression strains. Current workflows for single-cell isolation of bacteria and yeast are based on agar streaking or limiting dilution and are thus often inefficient and time-consuming.
B.SIGHT at your service
The B.SIGHT™ single-cell dispenser allows for efficient single-cell cloning of bacteria, yeast, and other small fungi. Using the B.SIGHT, one can directly isolate individual cells into liquid culture—label-free and automated, saving time and resources. This allows one to bypass streaking on agar and colony picking, which is a manual and time-consuming step.
