| Remarks |
These findings are highly consistent with the RNA and protein data described in the Human Protein Atlas (Tissue expression PLAP). The protein atlas data also suggest the uterus as an alternative source of limited PLAP expression besides placenta. That lung was also described in the protein atlas as a source of very limited PLAP RNA amounts cannot be explained by findings in this analysis.
