Figure 2From: In-depth proteomic analysis of a mollusc shell: acid-soluble and acid-insoluble matrix of the limpet Lottia gigantea PAGE comparison of acid-soluble and acid-insoluble matrix. Molecular weight markers are indicated at the left. S, acid soluble matrix; I, acid-insoluble matrix. The sections for in-gel digestion are indicated at the right of each lane. With longer exposure times sections 1–8 of the acid-insoluble sample became a feature-less smear, while faint bands became apparent in sections 9–12.Back to article page
