Catalog Number: (318701-500ML)
Supplier: SIGMA ALDRICH MICROSCOPY
Description: 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.

Melanin Bleach Kit

Catalog Number: (SHH0021-1KT)
Supplier: SIGMA ALDRICH MICROSCOPY
Description: An easy to use two step kit that reduces melanin while preserving delicate tissue, cytologic detail, and antigens. Heavy melanin pigment in the cells can obscure cellular morphology and subsequently impair interpretation when using routine or special histochemical stains. The melanin bleach kit enables the removal of melanin from tissue sections allowing for positive staining to be interpreted correctly. A two step kit that does not require mixing. Used before staining to reduce melanin while preserving delicate tissue, cytologic detail, and antigens.
