Bromcresol grønt natriumsalt in ACS Reagent grade water ≥90% (by HPLC), Sigma-Aldrich®

Leverandør: SIGMA ALDRICH MICROSCOPY
Beskrivelse: Bromocresol Green (BCG), also known as bromcresol green, is a synthetic, anionic, triphenylmethane dye belonging to the phthalein and sulphonphthalein dyes group. It is commonly used as a pH indicator as it changes colour from yellow to blue-green at pH 3,8 to 5,4. The monosodium salt of bromocresol green is highly ionisable in water. The dye at a higher pH level produces a large and weakly lipophilic dianion.

Tetrabromphenolblåt, Sigma-Aldrich®

Leverandør: SIGMA ALDRICH MICROSCOPY
Beskrivelse: Tetrabromophenol Blue (TBPB) belongs to the group of sulfonephthalein acid-base indicators. It is employed in the potentiometric titration of the halogens with Hg₂(NO₃)₂. In addition, it has been used as a dye indicator in urine dipstick test to detect proteinuria. In this assay, with increasing concentration of urinary protein, TBPB sequentially changes colour from pale green to blue. Binding of TBPB to proteins is dependent on pH.

1,3-Dihydroxynaphthalen ≥99.00%, crystalline, Sigma-Aldrich®

Leverandør: SIGMA ALDRICH MICROSCOPY
Beskrivelse: 1,3-Dihydroxynaphthalene is a dye intermediate forming stable colors when applied with particular mordants and in mixtures with other oxidising dyes. This specific reagent is intended for the quantitative colorimetric determination of alduronic acids, such as glucuronic acid from urine. The mutagenicity of ozonation derivatives of 1,3-dihydroxynaphthalene against several Salmonella typhimurium strains has been studied.
