The design of a synthetic operon encoding both the secretory apparatus and the structural monomers of curli fibers is described. Overproduction of these amyloids and adherent polymers allows a measurable gain of adherence of the E. coli chassis1. Easy ways to visualize and quantify adherence are explained.

The applicability of the clonogenic assay for evaluating reproductive viability has been established for more than 50 years. Here we demonstrate the general procedure for performing the clonogenic assay with adherent cells.
FAQs
Differential attachment acts as the selection step: cells with stronger attachment remain associated with the culture vessel, whereas cells with weaker attachment are more likely to be removed during washing or transfer. The resulting population is therefore enriched by a physical behavior rather than by a direct identity marker, which can reduce population complexity before later biological analyses.
Defined culture conditions influence which cells remain attached and which become available for removal. Because enrichment depends on relative attachment strength, changing the culture context can alter the composition and recovery of the retained population. Maintaining the intended conditions is therefore important for producing comparable preparations across experiments and for interpreting differences in cell behavior reliably.
A modified protocol changes selected adherence steps to address the balance between enrichment and recovery. More aggressive separation may reduce unwanted cells but also affect how many selected cells are retained, while adjusted handling can support better recovery. The modification is useful when the standard procedure does not provide the desired population quality or yield for downstream work.
The workflow begins by placing a mixed cell population under the defined culture conditions and allowing attachment behavior to develop. The vessel then retains the adherent fraction, while nonadherent cells are removed through washing or transferred away. The retained cells can subsequently be used to prepare a more uniform population for expansion, characterization, or further experiments.
A useful outcome is a population with fewer unwanted cells and greater uniformity than the starting mixture. Researchers can then examine the preparation through characterization or downstream experiments, comparing cell behavior or other study outcomes with the needs of the project. The method improves experimental consistency when the retained population is sufficiently enriched for its intended use.
This approach is useful when mixed populations complicate studies of cell behavior, differentiation, or tissue-related processes. Enriching cells before expansion or characterization can reduce unwanted cellular contributions and make subsequent observations easier to interpret. Its value lies in preparing a more consistent starting population, supporting downstream experiments that depend on clearer cellular composition.
