Papanicolaou EA36 Stain Kit

The Papanicolaou stain is the established standard in cytology. Originally developed to evaluate estrogen levels in vaginal epithelium and to detect pathogens such as Candida and Trichomonas in the genital tract, this method combines Orange G6? with either EA36? or EA50. This formulation produces vivid green, blue, and pink cytoplasmic staining. Key features include bright, transparent cytoplasm and sharp visualization of nuclear membranes, nucleoli, and chromatin structures. The Pap stain is particularly effective for exfoliated cell specimens, rendering nuclei blue to black while staining the cytoplasm of keratinizing squamous cells pink to orange-red.

The Papanicolaou EA36 Stain? Kit utilizes the EA36 solution for cytoplasmic staining and pairs it with a non-toxic, modified Hematoxylin solution? for nuclear counterstaining. Compared to EA50, the EA36 solution is preferred specifically for gynecological cytology, making it ideal for cervical cancer screening and the detection of precancerous lesions.
