Immunohistochemical evaluation of mucin expression in precancerous tissue of stomach
Aim - to assess the profile of mucins (MUC1, MUC2, MUC5AC) in gastric mucosa through immunohistochemical method. To identify metaplastic areas in gastric mucosa there was used chromoendoscopy with 0,5 % solution of methylene blue, the expression of the mucins profile was determined using immunohisto...

To identify metaplastic areas in gastric mucosa there was used chromoendoscopy with 0,5 % solution of methylene blue, the expression of the mucins profile was determined using immunohistochemistry with MUC1, MUC5AC, MUC2 and MUC6 antibodies (clone Ma695, clone CLH2, Ccp58 and CLH5, "Novocastra" Great Britain).
