PAGE comparison of acid-soluble matrices from shells. Molecular weight markers are indicated at the left. Each lane was loaded with 200 μg of matrix in a volume of 30 μl. A, matrices of shells cleaned with different sodium hypochlorite protocols. Lane A, 2 h hypochlorite at room temperature; lane B, 2 h hypochlorite with 2 x 5 min ultrasound treatment at the start of each hour; lane C, cleaned with hypochlorite for 24 h with 2 x 5 min ultrasound bursts as before and one after 24 h. B, matrices of different shells, all cleaned with hypochlorite according to protocol B (2 h hypochlorite, 2 x 5 min ultrasound).
