Vector® Hematoxylin QS (H-3404), a modification of Mayer’s
hematoxylin developed especially for immunocytochemistry,
provides crisp blue nuclear staining. This formula is ready-touse
without filtration, requires no separate “blueing” step,
and stains in less than 45 seconds. Vector® Hematoxylin QS
contains no mercury and provides excellent color contrast with
most commonly used peroxidase and alkaline phosphatase
substrates. This counterstain is suitable for use with nonaqueous
and aqueous mountants.
