A monoclonal antibody, GB17, was obtained from a hybridoma produced following murine immunization with isolated human term syncytiotrophoblastic microvilli. Immunohistological studies demonstrated the GB17 antigen to be present on syncytiotrophoblast of human term, first- and second trimester placenta, but not on human extravillous trophoblast or baboon placental trophoblast. Other normal adult human tissues and transformed cell lines tested were non-reactive with this antibody. Radio-iodinated term syncytiotrophoblastic microvillous protein was immunoprecipitated by GB17, and shown by sodium dodecyl sulfate--polyacrylamide gel electrophoresis to migrate as a single protein band at 175 kDa. The restricted tissue specificity suggests that the GB17 antigen could be useful for the development of a contragestational vaccine.

D014018 Tissue Distribution Accumulation of a drug or chemical substance in various organs (including those not relevant to its pharmacologic or therapeutic action). This distribution depends on the blood flow or perfusion rate of the organ, the ability of the drug to penetrate organ membranes, tissue specificity, protein binding. The distribution is usually expressed as tissue to plasma ratios. Distribution, Tissue,Distributions, Tissue,Tissue Distributions
D014327 Trophoblasts Cells lining the outside of the BLASTOCYST. After binding to the ENDOMETRIUM, trophoblasts develop into two distinct layers, an inner layer of mononuclear cytotrophoblasts and an outer layer of continuous multinuclear cytoplasm, the syncytiotrophoblasts, which form the early fetal-maternal interface (PLACENTA).
