The inks in accordance with the invention may have a peak transmission in the visible spectrum at a wavelength of from 322 nm to 716 nm or having a lineal UV-Vis spectrum with no visible peak transmission between 250 nm and 950 nm. When applied to a tissue specimen the ink compositions do not bleed onto adjacent tissue margins. When view under a microscope the color of the ink compositions can be distinguished from each other."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Ink for marking a tissue specimen","description":"An ink composition for marking a tissue specimen is provided.
