| pubmed-article:7818776 | pubmed:abstractText | The presence of nucleated erythrocytes was studied before and after enrichment with immunomagnetic beads and monoclonal antiglycophorin A (anti-GPA) antibody in the peripheral venous blood of 11 pregnant women at 10-16 weeks of gestation. Nucleated erythrocytes were identified by alkaline phosphatase antialkaline phosphatase immunostaining by means of anti-GPA antibody. In the unenriched cell samples, nucleated erythrocytes were found at frequencies of 1/2,800-1/83,000 in 6 cases. The frequency of nucleated erythrocytes was increased up to 6 times by the enrichment. | lld:pubmed |
