Integral membrane proteins anchor to the cell surface and span the lipid bilayer by an α-helix of 17-30 amino acids, the transmembrane segment. However, little is known about the association of this α-helix and the lipid bilayer. In the present stu

Pregnancy-associated plasma protein-A was assayed in the blood of 347 women during pregnancy, using a new primary standard of PAPP-A as reference. The protein was assayed by antibody-antigen crossed electrophoresis with the lower limit of confident a

Summary Microvillous M-PAP and A-PAP were purified to homogeneity from butanol extracts of syncytiotrophoblastic microvillous membranes using DEAE Sepharose CL-6B chromatography. The two isoenzymes had indistinguishable pH optima and K m values. Unde

This study was designed as an assessment of the clinical value of total estriol, placental lactogen (hPL), pregnancy specific glycoprotein (SP1), pregnancy-associated plasma protein-A (PAPP-A) and placental protein 5 (PP5), measured in a single sampl

Human placental microvillous alkaline phosphatase (M-PLAP) was extracted from microvilli either by butanol extraction or subtilisin proteolysis. The data indicate that subtilisin cleavage of PLAP removes a membrane-binding domain of approximately 200

Summary Pregnancy-associated plasma protein A (PAPP-A) has been obtained in an enriched state under mild conditions of purification involving cibacron blue dye-ligand chromatography, negative antibody-affinity chromatography and gel filtration. The p

The activities of five enzymes, isocitrate dehydrogenase, glucose-6-phosphate dehydrogenase, 6-phosphogluconate dehydrogenase, phosphohexose isomerase and lactate dehydrogenase have been measured in amniotic fluid cells at different stages of pregnan

α-fetoprotein (A.F.P.) has been measured in the amniotic fluids of thirty-one pregnancies leading to anencephaly (or anencephaly and spina bifida), three leading to spina bifida, and three leading to hydrocephaly (or hydrocephaly and spina bifida).

A protein factor has been found in serum which converts the M form of placental alkaline phosphatase (PLAP) to the A and B forms. The identity of the conversion products has been confirmed by analysis of their dimers and polypeptides. Proteolysis is

Summary A high molecular weight form of human placental alkaline phosphatase has been detected in extracts of placenta at term by electrophoresis in starch gels containing 0.5 per cent Triton X-100. The enzyme has a mobility intermediate between the
