Hi Yan

You should be able to blue your sections just by running under tap water, but you can try making your own blueing solution - I use Scott's solution (20 g/l of sodium bicarbonate and 3.5 g/l of magnesium sulphate 7-hydrate). After haeamtoxylin, rinse slides in tap water, then immerse in Scott's for 30s-1min, then rinse in tap water before eosin.

Joey.
