gentian Violet |
Homework Answers
In this case, the dilution system is focused in the counting of white blood cells. For this a counting chamber is used with the lysed red blood cells, in order to fix only the white blood cells (WBC). To stain the nucleus of WBC, the gentian violet is used giving a light violet blue coloration under the microscope. So, the correct answer is gentian violet
