5-Fluorouracil has been used to induce apoptosis in cells. It has been used as a chemosensitising agent. A potent antitumor agent that affects pyrimidine synthesis by inhibiting thymidylate synthetase, thus depleting intracellular dTTP pools. It is metabolized to ribonucleotides and deoxyribonucleotides, which can be incorporated into RNA and DNA. Treatment of cells with 5-FU leads to an accumulation of cells in S-phase and has been shown to induce p53 dependent apoptosis.

Sunset yellow FCF is a food dye, which is is substantially used in various food preparations. It is a orange-red coloured crystal, that is soluble in water and ethanol. It is used in treating bone metabolic diseases, dermatological disorders, respiratory illness etc. It can alter the functional responses of splenocytes at non-cytotoxic dose. It promotes immune suppression. Relative expression of surface receptors in T and B cells can be altered by sunset yellow FCF.

Supplier: SIGMA ALDRICH MICROSCOPY

Suitable for use with Sigma Silver Stain, Modified Steiner-Steiner, Procedure No. HT101, and other silver impregnation techniques.

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.
