摘要
Expansins are proteins that loosen plant cell walls but lack enzymatic activity. Here we describe two protocols tailored to measure the biomechanical activity of bacterial expansin. The first assay relies on the weakening of filter paper by expansin. The second assay is based on induction of creep (long-term, irreversible extension) of plant cell wall samples.
