| Upon staining, these round bacteria are visualized in clumps that resemble bunches of grapes. |
| Small samples were taken from the mixture, and living and dead cells were scored in quadruplicate using trypan-blue staining. |
| Predominantly in the tangential walls, primary pit fields of high density are conspicuously labelled by aniline blue staining of callose. |
| Paul Ehrlich improved on Koch's staining procedure, using aniline instead of ammonia and fuchsin instead of methylene blue. |
| Masson specified a dye he called Ponceau de xylidine for a variant of his trichrome staining method. |
| It was within the lepromatous skin nodules using primitive staining techniques that he saw masses of rodshaped bodies. |
