This one-step Dewaxing/Antigen Retrieval Buffer is a rapid reagent for paraffin slides pretreatment. There is no need to do the traditional three times of xylene dewaxing, three to five times of gradient ethanol hydration, all shorten to one solution.The operation time is effectively shortened, the cumbersome operation steps are simplified so the variables in operation are reduced, and the stability is improved. The Dewaxing/Antigen Retrieval Buffer applies new environmental protection technology is not only reduces the harm to the body, but also cause no pollution to the environment.
