Lead citrate is a compound of lead and citrate that is primarily used as an enhancer for heavy metal staining in electron microscopy. [2] This salt binds to osmium and uranyl acetate and enhances contrast in many cellular structures. Lead citrate is highly reactive with carbon dioxide.
Immunohistochemistry or IHC staining of tissue sections (or immunocytochemistry, which is the staining of cells), is perhaps the most commonly applied immunostaining technique. [2] While the first cases of IHC staining used fluorescent dyes (see immunofluorescence ), other non-fluorescent methods using enzymes such as peroxidase (see ...
Staining is a technique used to enhance contrast in samples, generally at the microscopic level. ... (III) nitrate, lead acetate, lead citrate, lead(II) nitrate, ...
Uranyl acetate staining is simple and quick to perform and one can examine the sample within a few minutes after staining. Some biological samples are not amenable to uranyl acetate staining and, in these cases, alternative staining techniques and or low-voltage electron microscopy technique may be more suitable.
In contrast to H&E, which is used as a general stain, there are many techniques that more selectively stain cells, cellular components, and specific substances. [12] A commonly performed histochemical technique that targets a specific chemical is the Perls' Prussian blue reaction, used to demonstrate iron deposits [ 12 ] in diseases like ...
Robert F. Kennedy Jr.'s raspy voice was on full display when his high-stakes confirmation hearing got underway Wednesday -- as lawmakers grilled President Trump’s controversial pick to lead the ...
Due to its short staining time, Diff-Quik stain is often used for initial screening of cytopathology specimens. This staining technique allows the cytotechnologist or pathologist to quickly assess the adequacy of the specimen, identify possible neoplastic or inflammatory changes, and decide whether or not additional staining is required. [4] [9 ...
