Primarily probably the most usually used histological stain, hematoxylin is a pure compound extracted from a species of tree current in Mexico and the West Indies. The extracted compound is oxidized to supply hematein, the energetic staining ingredient of the hematoxylin stain.
The manufacturing of histological staining choices is an art work. Just some laboratories are in a position to making a stain of reliable vibrance. At Nationwide Diagnostics we’ve now gone one step further. Our proprietary methods acquire the most effective administration of the ripening course of, resulting in the one commercially on the market Harris’ Hematoxylin with a full one 12 months shelf life.
Histo-Clear II, like its predecessor Histo-Clear, is a safer histological clearing agent that leads to the manufacturing of high-quality tissue slides. Histo-Clear II is unhazardous and totally biodegradable, thus decreasing disposal costs. Histo-Clear II has a vastly diminished citrus odor as compared with totally different citrus-based histological clearing brokers.
Discover: Histo-Clear II is simply not appropriate with many synthetic mounting media. Histo-Clear II is a long-standing favorite dry mounting procedures and aqueous mounting. Please affirm compatibility alongside along with your mounting media sooner than using Histo-Clear II with in wet-mounting with synthetic media.
