Which fixatives can be used with Alcian blue 1.0?

Explanation:
Alcian blue 1.0 binds to sulfated mucins, so the fixation must preserve these acidic groups without extracting them. Neutral buffered formalin keeps the sulfated mucins intact and preserves tissue structure, making it suitable for Alcian blue 1.0 staining. Bouin’s fixative also preserves sulfated mucins well and provides good morphological detail, so it’s compatible too. Unbuffered formalin can be too acidic and may alter or extract mucins, leading to weaker or inconsistent staining. So, neutral buffered formalin and Bouin’s solution are both appropriate fixatives for Alcian blue 1.0.
