Solvent violet 9, technical grade dye contents
CAS :<p>Solvent Violet 9 is a dye that has antimicrobial activity. It is used in diagnostic tests for infectious diseases and eye disorders. Solvent Violet 9 has shown to inhibit the growth of bacteria, fungi, and protozoa. This dye binds to fatty acids found on the surface of corneal endothelial cells and prevents bacterial attachment. Diazonium salt is used to synthesize this dye, which can be hydrolyzed by hydrochloric acid to form hydrogen bond with benzalkonium chloride. The absorption enhancer enhances the color of this dye when it is applied to clothing or other materials. The binding constants for this dye have been measured using an experimental technique called spectrophotometry. This dye also has anti-inflammatory properties due to its ability to bind with antimicrobial peptides and inhibit prostaglandin synthesis in inflammatory diseases such as rhizoma gastrodiae.</p>Formule :C25H31N3ODegré de pureté :(%) Min. 80%Masse moléculaire :389.53 g/molAcid Red 154

CAS :<p>Please enquire for more information about C.I.Acid Yellow 19 including the price, delivery time and more detailed product information at the technical inquiry form on this page</p>Degré de pureté :Min. 95%C.I.Direct green 28
CAS :<p>C.I.Direct green 28 is a site-specific fluorescent dye that binds to guanine nucleotide-binding proteins, which are involved in the regulation of heart function and signal pathways. The α subunit of these proteins has been shown to bind C.I.Direct green 28, with a hydroxyl group on the amino terminus and an ubiquitin ligase at the carboxyl terminus. This binding inhibits polymerase chain reaction (PCR) amplification by interfering with the ubiquitin proteasome pathway, which results in decreased light emission and hematopoietic cell production. This activity is hypothesized to be due to the inhibition of ATPase activity by C.I.Direct green 28, which leads to decreased phosphorylation of E1A-activating enzyme and increased phosphorylation of E2F-repressing enzyme, preventing DNA replication through transcriptional activation of erythroid transcription factors and halting progression through G1/S phase</p>Degré de pureté :Min. 95%C.I.Vat green 17
