Monoclonal antibodies block the bromelain-mediated release of human placental alkaline phosphatase from cultured cancer cells. 1985

R Jemmerson, and J L Millan, and F G Klier, and W H Fishman

Certain monoclonal antibodies (mAbs) to human placental alkaline phosphatase (PLAP) block bromelain cleavage of a 2-kDa segment from each of the two polypeptide chains of PLAP. These mAbs also prevent the release of PLAP from cultured cancer cell surfaces by bromelain. Such proteolysis-blocking mAbs serve as tools to specifically modify the molecular topography of cell surfaces by protease treatment.

UI MeSH Term Description Entries
D010920 Placenta A highly vascularized mammalian fetal-maternal organ and major site of transport of oxygen, nutrients, and fetal waste products. It includes a fetal portion (CHORIONIC VILLI) derived from TROPHOBLASTS and a maternal portion (DECIDUA) derived from the uterine ENDOMETRIUM. The placenta produces an array of steroid, protein and peptide hormones (PLACENTAL HORMONES). Placentoma, Normal,Placentome,Placentas,Placentomes
D011247 Pregnancy The status during which female mammals carry their developing young (EMBRYOS or FETUSES) in utero before birth, beginning from FERTILIZATION to BIRTH. Gestation,Pregnancies
D001963 Bromelains Protein-digesting and milk-clotting enzymes found in PINEAPPLE fruit juice and stem tissue. Enzymes from the two sources are distinguished as fruit bromelain and stem bromelain.
