Christmas Tree Stain for Spermatozoa The nuclear material within the cell is stained red by the Nuclear Fast Red stain . Sperm heads are usually well differentiated with the acrosome staining significantly less dense than the distal region of the head .
Christmas Tree Staining is another slide staining technique used to microscopically identify sperm . This method is much quicker than Sperm Hyliter . The sperm heads stain red and the sperm tails and other cells stain green . When viewed under a microscope, the sperm heads are fairly easy to spot and differentiate from the surrounding cells .
christmas tree stain A staining technique used to visualize sperm cells, so named because the different parts of the sperm cell take up different colours, simplifying microscopic identification . The tail shows as a yellow-green and the head shades of red and pink .
Christmas tree stain seemed to be equivalent to hematoxylin-eosin whereas alkaline fuchsin appeared to be ineffective in detect-ing spermatozoa .

Confirmatory tests for semen include the christmas tree stain and the p30/PSA RSID kit . For the christmas tree stain, the sample is extracted with sterile water in order to make a wet mount on a microscope slide . The sample is then heat-fixed to the slide and stained with nuclear fast red for 15 minutes, then rinsed with deionized water .
