General description

Fast Red Violet LB Salt, also known as 4′-amino-2′-chloro-5′-methylbenzanilide. It is a lipophilic amine with an aromatic system of moderate size and a hydrophilic diazonium cation. The diazonium salt is available commercially as a zinc chloride double salt. It comprises ≥90% dye content.

Application

  • Fast Red Violet LB Salt is suitable for quantitating alkaline phosphatase through histochemical, hematological, histological, and flow cytometric methods.
  • It has been used to study the role of TNF-α during fracture healing.
  • has been used for the detection of tartrate-resistant acid phosphatase (TRAP) in tissue sections.
