Note the brown staining of collagen. In a clinical histology laboratory, all specimens are initially stained with H&E and special or advanced stains are only ordered if additional information is needed to provide a more detailed analysis, for example to differentiate between two morphologically similar cancer types. Sometimes when results are poor, it is difficult or impossible to work out why because protocol changes have not been recorded. All our reagents are stored on the shelf above the staining bench. A reticulin stain occasionally helps to highlight the growth pattern of neoplasms.

Modern Multiplex Solutions for the Research Lab, Multiplexing addresses the need for researchers to assess multiple biomarkers (protein and/or nucleic acid markers) at specific locations within a tissue sample, Integrated Translational Research Solutions. Bacilli are rod-shaped bacterial organisms. There are two main techniques used for this, referred to as frozen sections and paraffin-embedded sections. Others are light sensitive and require storage in the dark. The complexity of some stains also works against the uses of automation. Leica Biosystems provides complete access to today's hottest topics in life sciences and in tissue-based translational research. However they are quite different in method and purpose and are now typically separated into a third category know as advanced stains.

These methods were sometimes also included as members of the special stains family. 0000016143 00000 n Standardize them as far as possible as they are frequently the cause of variable results. The first staining step is de-waxing which uses a solvent to remove the wax from the slide prior to staining. The process is more time-consuming than creating frozen sections, but provides better quality staining in most cases and the resultant samples (referred to as blocks) can be stored almost indefinitely. HT]o0}NO4Mj4j$$VPONn9>8_lNa]{pe0 @C6iA'InIS Inaccurate timing produces inconsistent results. Note that the basement membrane is very poorly stained in section B as a consequence.
