生物活性

Direct Red 254 is a bisazo dye for textile applications. Direct Red 254 can be used for amyloid tissue staining in basic research on neurodegenerative diseases (e.g., Alzheimer's disease)[1][2].

体外研究
(In Vitro)

Direct Red 254 (1% (w/v)) 可在体外对类淀粉样合成肽进行染色并诱导双折射:部分具有类淀粉样性质的肽段 (如肽段N14) 在染色后,在偏振光下显示出绿色双折射。这是淀粉样沉积物的一个典型特征[1]
Direct Red 254 可以被有效生物脱色,其脱色效率受其分子结构和在水溶液中聚集行为的影响[2]

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
