Stains

Overcome normal optical limitations in microscopic studies by highlighting specific structures with stains and reagents and then protect samples with fixatives. The fast-acting dyes create strong contrasts between cell components for easier detection or analyses. Sensitive attractions to certain organelle or cellular components differ among offered stains, allowing precise testing modifications. Flexible in use, ready-to-use stains may be handled manually or in conjunction with automatic equipment.
