An inert, synthetic, sucrose polymer (Ficoll) has been found to have a protective effect on leucocytes during incubation for cytochemical reactions at 37 degrees C. This permits enzyme cytochemistry to be performed on unfixed bone marrow and peripheral blood smears, and on leucocytes cultured in vitro, thus avoiding enzyme inhibition by the use of a fixative. The technique is suitable for the demonstration of both cytoplasmic and intramitochondrial dehydrogenase enzyme activity.
一种惰性合成蔗糖聚合物(聚蔗糖)已被发现,在37℃进行细胞化学反应孵育期间,对白细胞具有保护作用。这使得酶细胞化学能够在未固定的骨髓和外周血涂片以及体外培养的白细胞上进行,从而避免了因使用固定剂而导致的酶抑制。该技术适用于细胞质和线粒体内脱氢酶活性的显示。
