Why can't methylene blue be used for the negative stain technique? Explain the difference between a cationic dye and an anionic dye in terms of cell staining. What control "experiment" would you do to examine the effects of repair in the presence of a mutagen? How is Safranin staining...
We compared a simple, one-step staining procedure using a mixture of methylene blue and gentian violet to Gram stain for the detection of gonococcal urethritis. The sensitivity and specificity of both Gram stain and methylene blue/gentia... SN Taylor,RP Dicarlo,DH Martin - 《Sexually Trans...
In this study a specialist will study the shape of the spermatozoa in the andrology laboratory. To do this, the specialist will stain a drop of semen and observe the morphology of the stained spermatozoa under the microscope. The most common way to stain spermatozoa is using methylene blue ...

. The reticulocytes in the interface layer were harvested and washed three times with RPMI 1640 medium. The reticulocyte purity was calculated from thin blood smear samples with new methylene blue stain under light microscopy and thiazole orange (TO) staining of the enriched reticulocytes. A total...
