The aim of the present study was to compare the efficiency of various conventional single and dual staining protocols for assessment of spermatozoa attributes. The efficiency of single stains such as Eosin-Nigrosin (EN) and Trypan blue (TB) for viability and Giemsa (G) for acrosome integrity vis-a-vis dual stains such as Trypan blue-Giemsa (TB-G) and Eosin Nigrosin-Giemsa (EN-G) were ... https://www.chiggate.com/eeboo-memory-matching-game-animal-pre-school-supply/
