Fig. 12. Congo Red (CR) staining of hagfish slime. Slime threads (but not mucins)
bound CR, but only threads from slime that was physically perturbed showed
metachromasia. (A) Bright field image of slime threads from unperturbed slime.
(B) Dark-field (polarisers crossed) image of same threads. Note the lack of CR
metachromasia in most of the threads. (C) Bright field image of threads from
perturbed slime. (D) Same as C, dark field. (E) Bright field image showing
bundling of slime threads in perturbed slime. (F) Same as E, dark field. Bar,
10 µm.
