G1201-1L Citric Acid Buffer Solution Antigen Retrieval Buffer Dry Powder

After the cells or tissues are fixed with paraformaldehyde, formaldehyde or other aldehyde reagents, they will lead to cross-linking between proteins, thus obscuring the antigen sites of the samples, leading to the weakening of staining signals during immunostaining, and even some false positive staining results. A widely used citric acid buffer (pH6.0) is used in the antigen repair solution, which can effectively remove the cross-linking between proteins caused by aldehyde fixation reagents and fully expose the antigen epitopes in samples such as paraffin sections. Thus, the immunostaining effect is greatly improved.
