X-Gluc cyclohexanamine is a dye used to detect β-glucuronidase (GUS) activity and serves as a marker for gene expression, enabling the detection of target gene expression.

L-ascorbic acid 2-phosphate (2-Phospho-L-ascorbic acid) magnesium hydrate is a long-acting vitamin C derivative that can stimulate collagen formation and expression. L-ascorbic acid 2-phosphate magnesium hydrate can be used as a culture medium supplement for the osteogenic differentiation of human adipose stem cells (hASCs). L-ascorbic acid 2-phosphate magnesium hydrate increases alkaline phosphatase (ALP) activity and expression of runx2A in hASCs during the osteogenic differentiation.

Direct Red 80 is a tetra azo dye. It can be used to detect amyloid and can magnify the usual birefringence of collagen fibers in tissue sections.
