Hi. I'm not an expert in oocytes but I use plenty of antibodies daily. I was looking in pubmed for possible antibody references that could help you, and indeed most of the antibodies used in this topic turn out to be exclusively for Western Blot and IP use.
So, it depends in the protein you are targeting. Have in mind that the brochures tell you in which assays you can use the antibody.
Also, answering your question, yes, monoclonal antibodies can be used in ICC assays; however, depending the sample, the dilution must be adjusted and standardized.
