Image Unavailable-HT5011-1CS

Formalin 10% histological fixative, neutral buffered, Sigma-Aldrich®

Catalog Number: (HT5011-1CS)
Supplier: SIGMA ALDRICH MICROSCOPY
Description: Formaldehyde is both a non-coagulant and an additive fixative. Formaldehyde is known to penetrate tissue quickly, but the fixation process may take a long time to form the various cross links with tissue proteins. Formalin fixation is thought to form cross links between the aldehydes and the proteins, creating a gel, thus retaining cellular constituents in their <i>in vivo</i> relationship. Once properly fixed, the tissue should be able to withstand the subsequent stages of tissue processing or staining. Although there is no true universal fixative, 10% neutral buffered formalin (NBF) is perhaps the most commonly used fixative throughout the world for light microscopy and is a somewhat forgiving fixative. Of the dozens and dozens of available fixatives, it is hard to imagine a fixative more commonly used than 10% NBF. 10% neutral buffered formalin is well suited for large throughput laboratories, and requires a relatively short period of fixation, but can also be used for the long-term storage of tissue.

Giemsa's stain, certified by the Biological Stain Commission, Sigma-Aldrich®

Supplier: SIGMA ALDRICH MICROSCOPY
Description: Certified for Giemsa stain for blood films and for the Wolbach′s Giemsa method for paraffin sections. Giemsa is a versatile polychromatic stain, which is suitable for staining a diverse range of specimens. It is a buffered thiazine-eosinate solution designed to provide coloration of blood cells. Giemsa’s stain is frequently used for diagnostic purposes in hematology to differentiate the nuclear and cytoplasmic morphology of platelets, RBCs, WBCs, and parasites. It is frequently used in combination with other dye solutions as May-Grunwald’s solution for Pappenheim (MGG) and Wright-Giemsa. The Giemsa stain was adapted to histology due to its unique staining of chromatin, nuclear membranes, and cytoplasmic elements. Giemsa′s staining solution is composed of methylene blue, azure, and eosin.

Acid red 27 ≥85-95% (dye content), Sigma-Aldrich®

Supplier: SIGMA ALDRICH MICROSCOPY
Description: Amaranth has been used as a dye for the microscopic visualization of crop contraction in blowflies. It has been used in the electrophoresis gel to track the migration front of the electrode buffer.

Histo/Zyme

Supplier: SIGMA ALDRICH MICROSCOPY
Description: Histo/Zyme is a stabilized proteolytic enzyme in buffered solution, used to unmask immunoreactive sites altered by fixation and/or the embedding process. Treatment with a proteolytic enzyme in immunohistochemistry (IHC) is required to digest excess linkages and expose the antigen. The use of Histo/Zyme results in superior staining over traditionally used enzyme pretreatments, such as pepsin and trypsin. Moreover, Histo/Zyme requires only a brief incubation at room temperature. Performing antigen recovery with Histo/Zyme will allow you to dilute the primary antibody 5 to 10 fold further and achieve optimal staining.

Xylene cyanole FF ≥75% (dye content), Sigma-Aldrich®

Supplier: SIGMA ALDRICH MICROSCOPY
Description: Xylene cyanol is often used as a tracking dye during agarose or polyacrylamide gel electrophoresis. It has a slightly negative charge and will migrate in the same direction as DNA, allowing the user to monitor the progress of molecules moving through the gel. The tracking dye typically migrates with the DNA molecules around 5 kb. Xylene cyanol may also be used in loading buffer that facilitates the observation of the sample during gel loading and electrophoresis.
