RICHARD-ALLAN SCIENTIFIC COMPANY
This staining kit simplifies quick differential staining blood smears and fine needle aspirates with its compact size making it specially ideal for FNA carts. With the Rapid-Chrome Kwik- Diff Staining Kit, all of the necessary reagents and accessories are supplied in one convenient, portable tray. Reagents are sequentially aligned so that the user can dip slides progressively from jar to jar. Additionally, die-cut slots in the tray base accommodate jar lids in order to reduce potential cross-contamination of reagents as well as required counter space. This kit can stain approximately 100 slides, although the actual number may vary based upon sample type and thickness.

EA-36, -50, -65 and Modified EA are ready-to-use cytoplasmic counterstains used for gynecological and non-gynecological cytology specimens. These products contain common dyes and reagent solvents used in traditional EA formulations. A well-preserved or fixed slide with adequate exposure to 95% alcohol or a commercial spray fixative is highly recommended for optimal staining results. Cellular results are traditional as well, with basal or intermediate cells staining a blue-green hue and surface cells staining a pink-red hue. This multicolored effect is due to dye uptake by various cells and their affinities for the specific dyes.EA-65 is used in conjunction with OG-6 for the staining of non-gynecological specimens. This formulation contains less dye resulting in lighter staining of highly mucoid sample types common in non-gynecological cytology.

Gill Hematoxylin 1, 2, and 3 are rapid, progressive hematoxylins that are widely known and respected in the histology and cytology fields. They offer convenience and choice of stain intensity. Gill hematoxylins are ready to use and will provide familiar, consistent, well-delineated results. Stain filtering may be needed to remove sheen caused by oxidation or cells shed off of slides in the cytology staining process. Gill 1 is the least intense stain and is most commonly used in cytology and in special stains. Gill 2 is a moderately intense stain and is most commonly used in histology, with some limited use in cytology. Gill 3 is an intense stain and is exclusively used in histology as well as staining of plastic sections.

Tissue Marking Dyes are intended as an aid in the orientation, of excised surgical specimens through frozen sectioning, processing, and sectioning, and subsequent microscopic examination of tissues. The marking of multiple margins with these dyes is especially useful for identification in skin biopsies, a technique known as Moh’s surgery. These dyes are normally applied to fresh tissue but may also be used with fixed tissue. Whether fresh or fixed, the tissue should be blotted to remove excess fluid from the surface before applying the dye. Tissue Marking Dyes will permanently bond to the tissue 1 to 2 minutes after application. The tissue can then be frozen and prepared for sectioning or placed in formalin or other fixatives and processed for paraffin embedding.

Potassium Permanganate Solution is the oxidizing agent in this technique. It is followed by an Oxalic Acid Solution to remove the excess permanganate. This step serves to enhance the subsequent staining of the reticular fibers. A sensitizing step using Ferric Ammonium Sulfate Solution impregnates the fibers, creating a metal-organic bond that is replaced by silver during subsequent treatment with Working Ammoniacal Silver Solution. To develop the visible silver, a Reducing Solution of dilute formaldehyde is used. The tissue structures that have been impregnated with the silver solution will now appear brown to black. Gold Chloride Solution is used to “tone” the sections, producing better contrast and clarity as the gold reacts and combines with the reduced silver. Unreduced silver is removed via treatment with Sodium Thiosulfate Solution. An optional nuclear fast red counterstain provides background staining as well as nuclear detail.

Alcian Blue reacts to compounds containing anionic groups such as acid mucosubstances and acid mucins. At pH 2.5, both carboxylated and sulfated acid mucosubstances are stained blue. Periodic acid is used to oxidize the tissue to form aldehyde groups that are demonstrated by Schiff Reagent. Glycogen and neutral mucosubstances as well as basement membranes will be stained magenta by Schiff Reagent, followed by a tap water rinse to develop and intensify its magenta hues. An optional counterstain may be used to provide nuclear detail. Hematoxylin 7211 is recommended; however, Kernechtrot Nuclear Fast Red may be used if a red nuclear stain is desired

Modified Grocott’s Methenamine Silver Stain Kit (Chromic Acid) is intended for use as an aid to identify fungal organisms and basement membranes in tissue sections for the diagnosis of general pathology specimens. Fungal cell walls are rich in polysaccharides known as glucans. Treatment with either periodic acid or chromic acid oxidizes these polysaccharides to form aldehyde groups; however, chromic acid is the stronger oxidizer. Chromic acid will achieve a greater degree of oxidation, rendering some chemical groups non-reactive with silver so that they are not demonstrated within the final stain. This greater level of oxidation also results in reduced background staining of basement membranes and collagen fibers, as well as more effective demonstration of Pneumocystis jiroveci (formerly classified as Pneumocystis carinii) and Histoplasma capsulatum (the causative organism of Histoplasmosis). After oxidation, Sodium Metabisulfite Solution removes residual Chromic Acid Solution from the tissue. The aldehyde groups react with the silver ions present in the Working Methenamine Silver Solution and reduce them to form visible metallic silver. Gold Chloride Solution tones the sections and intensifies the reduced silver by forming a silver-gold complex. Sodium Thiosulfate Solution removes any unreduced silver from the tissue sections, followed by Fast Green Stain Solution which produces a light green background to further enhance contrast.
