The formation of these bonds denatures protein and can result in the loss of antigenicity. In addition, the formaldehyde can form methylene bridges, which cross link tissue proteins, thus reducing the penetration of the tissue to large molecules such as antibodies.Ribo CC is a citrate buffer at a slightly acidic pH, which, at elevated temperatures, is capable of hydrolyzing the covalent bonds formed by formalin and formaldehyde in tissue. Removing these bonds allows renaturation of protein molecules and increases antibody accessibility. Often these changes result in significant gains in antibody binding and improved signal to noise ratios. The automated slide stainer heats the slide to the appropriate temperature and maintains the temperature for a specific time interval selected by the user. en
