The advantages of REAP stain are; better than routine Pap stain, excellent nuclear / cytoplasmic staining with better color intensity / transparency, cost effective as acetic acid replaces costly ethanol (25% of total cost of standard Pap stain), long term color preservation (more than 1 year without fading), quick procedure, staining of non epithelial cells like RBC/WBC/bacteria are well . It stain basic structures in red or pink color. Bond Dewax Solution was used to de-paraffinise FFPE sections. Best Answer. See full answer below. The different IHC protocols are represented schematically and summarized in a table that also lists advantages and disadvantages of each approach. Pros of Staining a Wood Floor. The advantages of negative staining are: bacteria are not heat fixed so they dont shrink, and. Others are general stains that add color to every cell. During the process of staining, the iodine and crystal violet would form a complex within the heat fixed cell, and in organisms that are gram-negative, this complex would be readily washed out by agents, such as alcohol or acetone, but would appear red as they retain only the counterstain. B: You pick specific organelles to view depending on what stain you use. Multiple stains can be used simultaneously to mark different cells with different colors. Also, what are the limitations of simple staining? Describe the acid-fast staining technique. The Gram stain The slides were completely air-dried following DAB staining to prevent non-specific DAB-Iron reagent interaction, then rehydrated in deionised water for staining with the Abcam Iron Stain kit (ab150674) for two-three minutes. course.
