Fast Red Violet LB is an azo dye that can be used to detect tartrate-resistant acid phosphatase (TRAP) and alkaline phosphatase (ALP)[1, 2]. Fast Red Violet LB, also known as carminic acid, is extracted from the scales of female cochineal insects[3]. Fast Red Violet LB can be used to study the role of TNF-α in fracture healing[4]. Fast Red Violet LB can stain naphthol AS-D chloroacetate esterase activity and can be used to detect granulocytes[5].
