Description
4-Methylumbelliferyl alpha-L-idopyranosiduronic acid sodium salt is a carbohydrate acid and organic sodium salt applied as an indicator. It is the fluorogenic substrate used in assays of α-L-Iduronidase and iduronate-2-sulfatase for identifying Hurler syndrome, also called mucopolysaccharidosis type I (MPS I). The disorder is characterized by α -L iduronidase enzyme deficiency, resulting in the buildup of glucosaminoglycans. Tests measure the chemical products 4-MU-α-IdoA or fluorophate 4-MU emitted following the enzymatic action of 4-Methylumbelliferyl alpha-L-idopyranosiduronic acid sodium salt. The substance is a white crystalline powder and is soluble in ethanol, methanol and water.

Acriflavine HCl
Catalog ID | Size | Pricing | |
---|---|---|---|
A-905-25 | 25 g | $ 70.00 |
Description
Acriflavine HCl is a compound predominantly used in cellular biology for fluorescence staining. It intercalates between the base pairs of DNA and RNA. Among the acridine dyes, acriflavine has the highest affinity for DNA. Acriflavine stains eukaryotic cells exceptionally well in humic substance environments. It provides a robust experimental consistency and reduces the effect of minor experimental errors. The binding of acriflavine to DNA can be observed from a characteristic red shift in an absorption spectrum. While having a high affinity for DNA, acriflavine is limited to euchromatin for both DNA and RNA.
Acriflavine has also been found to inhibit heterodimeric transcription factors, specifically called hypoxia-inducible factors (HIFs). Studying the hyperactivity of HIFs has become a popular in oncology research, where chemicals like acriflavine are used to disrupt HIF activity of malignant cells. HIFs are activated in hypoxic conditions and promote angiogenesis to alleviate stress. They are normally regulated through proline and asparagine hydroxylation. Acriflavine halts HIF activity, specifically by binding to a subdomain of HIF-1α and HIF-2α.
