Protocol for isolating cervico-vaginal fluid cells from Macaca mulatta to study immunological and functional changes...

Cervico-vaginal fluid represents an important biological fluid due to its proximity to gestational tissues, such as the cervix, fetal membranes, and myometrium. Here, we present a protocol to isolate cervico-vaginal fluid cells from Macaca mulatta. We describe steps for cervico-vaginal fluid collection, cervico-vaginal cell isolation for nuclear staining and immunophenotyping by flow cytometry, and protein-level detection and quantification by ELISA. This protocol can provide insights into altered immunological changes at the cervico-vaginal interface.
