Swiss mice were immunized with various antigens: polyvinylpyrrolidone (PVP), human serum transferrin (HST), bovine serum albumin (BSA) or tetanus toxoid (TT). Fifteen days after the last injection of antigen, the mice were infected with Plasmodium chabaudi AJ. Two weeks after the beginning of malarial infection, parasitaemia became latent and total(More)
A selective bi-site ELISA assay procedure for quantification of Lp[a] lipoprotein in human plasma based on linkage of apo[a] to apoB is described. The lipoproteins referred to as apo[a]:B were captured by a mixture of two anti-apo[a] monoclonal antibodies (K07, K09) and were revealed by a mixture of six anti-apoB monoclonal antibodies coupled to peroxidase.(More)
The use of mixtures of well-defined monoclonal antibodies may represent a step forward in the standardization of immunochemical assays. We developed and optimized working conditions for using such a mixture to determine apolipoprotein A-I in human sera by two independent techniques (electroimmuno- and immunonephelometric-assays). Six monoclonal antibodies,(More)
A monoclonal antibody (BIP 45) against human apolipoprotein B (apo B) was used to study the polymorphism of apo B in families and in unrelated subjects. BIP 45 bound to apo B-containing lipoprotein particles in one of three distinct patterns of immunoreactivity (strong, weak and intermediate). Family studies showed that these binding patterns result from(More)
The immunoreactivity of apolipoprotein B (apo B) in plasma obtained from 238 unrelated black African male subjects from the People's Republic of Congo was analysed by non-competitive Enzyme Linked-Immunosorbent Assay (ELISA) with monoclonal BIP 45 anti-LDL antibody. The polymorphism detected by BIP 45 monoclonal antibody is identical to the Ag(c,g)(More)
An epitope of Apolipoprotein B (ApoB), recognised by a monoclonal antibody BIP-45, is associated with the development of ischaemic heart disease (Duriez et al. 1988). We have examined the genetic relationships between this epitope and three Restriction Fragment Length Polymorphisms (RFLPs) of the gene for ApoB detected with the enzymes EcoRI, PvuII and XbaI(More)
The immunoreactivity of apolipoprotein B (apo B) in plasma samples obtained from a variety of subjects was analysed by non-competitive ELISA with a polyclonal and a monoclonal (BIP 45) anti-LDL antibody. Three populations were tested: the first, comprising 244 healthy male volunteers, provided reference values; the second consisted of a population(More)
Two monoclonal antibodies, A17 and A30, were raised against human apolipoprotein A-I (apo A-I). They were studied by competitive inhibition of 125I-labeled HDL3 with HDL subfractions, delipidated apo A-I, and complexes of dimyristoylphosphatidylcholine (DMPC) containing apo A-I and apo A-II. Immunoblotting located the A17 antibody on CNBr fragment 4 of apo(More)
