Haematoxylin
Haematoxylin is a naturally occurring dye extracted from the heartwood of the Logwood tree. It is a commonly used stain in histology and cytology laboratories for the visualization of cellular structures.

H&E staining was performed using haematoxylin (Vector Laboratories, Inc., Burlingame, CA) for 3 minutes, followed by 10 seconds of eosin (Wako). TRAP staining was performed with Naphthol AS-BI phosphate (Sigma), sodium nitrite (Wako), 0.08 M L(+)-tartaric acid (Wako), and pararosaniline hydrochloride (Sigma) in 0.1 M of sodium acetate buffer (pH 5.0) at 37 °C in an incubator for 20 minutes, followed by nuclear counterstaining with haematoxylin. Under an Olympus light microscope (Olympus, Tokyo, Japan), TRAP-positive multinuclear giant cells adjacent to the collagen fibres were identified as osteoclasts. We counted the osteoclasts that were present in regions of bone regeneration and measured the area that consisted of new collagen (Olympus cellSens standard version 1.13; Olympus). The number of osteoclasts in the decalcified bone area (mm−2) was represented by the number of osteoclasts in the new collagen area.

About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
