Immunoprecipitation of human adrenal microsomal antigen

Antigen-antibody reactions Immunoagglutination Immunoprecipitation

Direct immunoprecipitation of antigen with phage displaying immunoglobulin fragment.

Phage libraries may display hormones, receptors, antibody fragments, etc., by fusion to phage envelope proteins. This report describes the direct precipitation of phage-Fab-antigen complexes by polyethylene glycol precipitation, resulting in highly selective and efficient recovery of antigen from complex mixtures without nonspecific protein contamination. The method demonstrates efficiency and ...

Development of monoclonal antibodies to human microsomal epoxide hydrolase and analysis of "preneoplastic antigen"-like molecules.

Microsomal epoxide hydrolase (mEH) is a drug metabolizing enzyme which resides on the endoplasmic reticulum (ER) membrane and catalyzes the hydration of reactive epoxide intermediates that are formed by cytochrome P450s. mEH is also thought to have a role in bile acid transport on the plasma membrane of hepatocytes. It is speculated that efficient execution of such multiple functions is secured...

P-145: Role of Human Leukocyte Antigen in Miscarriage

Background: During pregnancy, the maternal immune system is in close contact with cells and tissue from the semiallogenic fetus .The human leucocyte antigen (HLA) class Ib molecules, HLA-E, -F and -G, are expressed at the materno-fetal interface. Because of the apparent immunoregulatory functions of these proteins, they may be involved in successful acceptance of the semi-allogenic fetus during...

Human platelet antigen polymorphism in bronchial asthma

Background: Asthma is recognized as a common cause of disability, of great economic cost, and of preventable deaths. In this study we aimed to test our hypothesis to evaluate the relationship between the Human Platelet Antigen-1(HPA-1) polymorphism and bronchial asthma and its severity, which would suggest genetic variances that may be responsible for expression or activation of these receptors...
