细胞学常规染色普遍使用巴氏(Papanicolaou)法,Papanicolaou Stain最初仅用于检测阴道上皮雌激素水平以及生殖道念珠菌、滴虫等病原体,橘黄G6与EA36或EA50联合使用,可将胞浆染成颜色鲜明的绿色、蓝色和粉色。目前大多数实验室采用成品染液,所以每种染液应注意其改良后的最佳条件,最终胞浆染色应透明可见,核染色质应很容易辨别出来;目前改良的巴氏染色液含有多种离子,具有多色性染色效能,染色后胞质鲜艳、透明性好以及核膜、核仁、染色质结构清晰。细胞核染色液主要为Harris苏木素染液,细胞质染色液主要为EA36染液、EA50染液;巴氏染色液用于细胞脱落标本,细胞核呈蓝色或黑色,角化鳞状细胞胞浆呈粉红或橘红色。
巴氏染色液 (Papanicolaou EA65) 细胞质染液采用EA65,细胞核染色采用无毒改良型苏木素染色液,EA65更适用于非妇科细胞学涂片染色。巴氏染色液是用苏木素、橙黄、伊红、磷钨酸、亮绿等配制而成,用于处理分泌物等细胞脱落标本,细胞核呈蓝色或黑色,角化鳞状细胞胞浆呈粉红或橘红色。该试剂仅用于科研领域,不适用于临床诊断或其他用途。

The Papanicolaou method is commonly used for routine cytological staining. Papanicolaou Stain was initially used only to assess estrogen levels in vaginal epithelium and detect pathogens such as Candida and Trichomonas in the genital tract. The combination of Orange G6 with EA36 or EA50 can stain the cytoplasm in distinct bright green, blue, and pink colors. Currently, most laboratories use ready‑to‑use staining solutions; therefore, the optimal conditions for each modified staining solution should be noted. The final cytoplasmic staining should be transparent and visible, and nuclear chromatin should be easily distinguishable. The currently modified Papanicolaou staining solution contains various ions and exhibits polychromatic staining efficiency, resulting in bright and transparent cytoplasm, as well as clear structures of the nuclear membrane, nucleolus, and chromatin. The main nuclear stain is Harris Hematoxylin Stain, and the main cytoplasmic stains are EA36 Stain and EA50 Stain. Papanicolaou Stain is used for exfoliated cell specimens: the cell nuclei appear blue or black, and the cytoplasm of keratinized squamous cells appears pink or orange‑red.
Papanicolaou Stain (Papanicolaou EA65) uses EA65 for cytoplasmic staining and a non‑toxic modified hematoxylin stain for nuclear staining. EA65 is more suitable for non‑gynecological cytological smears. Papanicolaou stain is prepared from hematoxylin, orange G, eosin, phosphotungstic acid, light green, etc. It is used for processing exfoliated cell specimens such as secretions. The cell nuclei appear blue or black, and the cytoplasm of keratinized squamous cells appears pink or orange-red. This reagent is for research use only and is not intended for clinical diagnostic or other purposes.
