The SpermBlue stain has been developed to stain all the components of the sperm (acrosome, head, midpiece and main piece of tail) differentially in different intensities of blue. SpermBlue can be used for all species.

New improved formula, extremely simple, only involves one step, as fixation and staining are done at the same time. It works equally well for smears of “raw” semen as well as swim-up/Percoll/Pure Sperm gradient preparations using most culture media.
