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河见,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 EA36) 细胞质染液采用EA36染色液,细胞核染色采用无毒改良型苏木素染色液,EA36 比EA50更适用于妇科细胞学涂片染色如筛查宫颈癌和癌前病变。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 detect vaginal epithelial estrogen levels and pathogens such as Candida and Trichomonas in the genital tract. The combination of Orange G6 with EA36 or EA50 allows the cytoplasm to be stained in distinct colors including green, blue, and pink. At present, most laboratories use ready‑to‑use staining solutions, so the optimal conditions for each modified staining solution should be noted. The final cytoplasmic staining should be transparent and clear, and nuclear chromatin should be easily distinguishable. Currently, modified Papanicolaou staining solutions contain various ions and exhibit polychromatic staining efficiency. After staining, the cytoplasm is bright and transparent, and the structures of the nuclear membrane, nucleolus, and chromatin are clear. The main nuclear stain is Harris hematoxylin solution, and the main cytoplasmic stains are EA36 solution and EA50 solution. Papanicolaou Stain is used for exfoliated cell specimens. Cell nuclei appear blue or black, and the cytoplasm of keratinized squamous cells appears pink or orange‑red.
Papanicolaou Stain Solution (Papanicolaou EA36) uses EA36 solution for cytoplasmic staining and non‑toxic modified hematoxylin solution for nuclear staining. EA36 is more suitable than EA50 for gynecological cytological smears, such as screening for cervical cancer and precancerous lesions. This reagent is for research use only and is not suitable for clinical diagnosis or other purposes.
