Decal Quick Clear utilizes hydrochloric acid and a chelating agent to quickly bind and remove all calcium from bone/calcified tissues. This allows the sample to then be sectioned with standard microtomy procedures. This reagent is a standard HCl decalcification reagent, for a more concentrated version and quicker rate decalcification see ScyTek's Decal Quick Clear solution (item: DQC). This solution is ideal for processing tissues that will undergo special staining and procedures other than Immunohistochemistry. Hydrochloric acid-based reagents can negatively affect staining results of immunohistochemical procedures and other decalcification solutions should be considered.
