Résumé

La phosphatase alkaline du placenta humain est un sialyglycoenzyme qui inhibe l'hémagglutination (HA) produite par leVirus influenzae A (PR-8). L'enzyme de poids moléculaire élevé donne un titre HA-I beaucoup plus grand que les enzymes de poids moléculaire inférieur L'élimination de l'acide sialique de l'enzyme par traitement à la neuraminidase ou par oxydation des carbohydrates avec du périodate ou par protéolyse amènent une réduction prononcée du titre de HA-I.
