Acriflavine fluorescent labeling reagent, Sigma-Aldrich®

Supplier: SIGMA ALDRICH MICROSCOPY

Acriflavine also interacts with HIF-1α (hypoxia-inducible factor 1 α) and HIF-2α, and thereby suppresses dimer formation of HIF-1 and transcriptional function. It also has negative effect on tumor growth and vascularization. Acriflavine also exhibits trypanocidal, antibacterial and antiviral activities.

Fluorinert™ FC-770, Sigma-Aldrich®

Supplier: SIGMA ALDRICH MICROSCOPY

Fluorinert™ belongs to the group of aliphatic compounds. It is considered as a pressure-transmitting medium because it is highly inert. Fluorinert™ Electronic Liquid FC-770 is a thermally stable, fully-fluorinated liquid that has ideal properties for use as a heat transfer fluid in a variety of industries. The inertness of Fluorinert™ FC-770 permits its use as a direct contact single and two-phase coolant in certain supercomputers and sensitive military electronics. Its high dielectric strength and electrical resistivity are ideal for applications in high voltage transformers and power electronics. In the semiconductor manufacturing industry, its wide liquid range makes Fluorinert™ liquid FC-770 suited for cooling ion implanters, dry etchers and CVD machines. Its low pour point also permits its use in thermal shock and test equipment.

Tetramethylrhodamine isothiocyanate Isomer R (6-TRITC isomer R), Sigma-Aldrich®

Supplier: SIGMA ALDRICH MICROSCOPY

Tetramethylrhodamine isothiocyanate Isomer R (TRITC) is the R isomer of tetramethylrhodamine isothiocyanate and is also known as 6-tetramethylrhodamine isothiocyanate. It is a strongly fluorescent compound soluble in ethanol, methanol, dimethylformamide, dimethylsulfoxide, and water. TRITC is a moderately-sized aminoxanthene dye carrying carboxylic acid and isothiocyanate substituents on the non-planar pendant phenyl ring. It forms a lipophilic cation in acidic pH and a hydrophilic zwitterion around neutral pH. The isothiocyanate group reacts with nucleophilic substituents (e.g., amino, hydroxyl, thiol) of biomolecules, providing the means of attaching a fluorescent label. TRITC also reacts with water and hydroxide ions and is unstable in aqueous solutions. TRITC is commercially available as a zwitterion or as a chloride.

Formalin 10% histological fixative, neutral buffered

Supplier: SIGMA ALDRICH MICROSCOPY

10% Neutral buffered formalin (NBF) is the most commonly used fixative for light microscopy. 10% NBF 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. Formalin fixation is thought to form between the aldehydes and the proteins, creating a gel, thus retaining cellular constituents in their in vivo relationship.

Bromocresol green sodium salt 0.04% in aqueous solution, Sigma-Aldrich®

Supplier: SIGMA ALDRICH MICROSCOPY

Bromocresol green is a sulfonephthalein dye. It is mainly used for measuring serum albumin. In acidic conditions, bromocresol green interacts with albumin, thereby resulting in an increase in absorbance at 630 nm. The change in absorbance is linked with the concentration of albumin. Bromocresol Green is also a pH indicator, changing from yellow (pH 3.8) to blue color (5.4). It is widely used as a colloidal pigment.

Poly-L-lysine hydrobromide

Supplier: SIGMA ALDRICH MICROSCOPY

Poly-L-lysine is a positively charged amino acid polymer with approximately one HBr per lysine residue. The hydrobromide allows the poly-L-lysine to be in a crystalline form soluble in water. A small amount of product may be found in the beta structure because the HBr interferes with hydrogen bonding between amino and either the carboxyl groups or N or O containing moieties.
