By competition radioimmune assays with antisera against AKR murine leukemia virus (MuLV) gp 71 or antisera against xenotropic virus, and iodinated AKR MuLV gp71 or BALB(X) gp71, antigens serologically indistinguishable from the viral antigens can be detected in tissues of normal mice in the absence of overt virus expression. An antigen serologically indistinguishable from AKR MuLV gp71 can be r...

background: hydatidosis is one of the cosmopolitan parasitic zoonoses caused by the larval stage of echinococcus granulosus. diagnosis of hydatidosis is still an unresolved problem. serological tests using crude antigens for diagnosis of e. granulosus are sensi-tive, however their specificity are not satisfactory. therefore, who recommended spe-cific serological methods using specific antigens,...

Background: Glycophorin A (GPA) is one of two glycoproteins found on the surface human red blood cells (RBCs) that constitute MNS group system. The structure GPA’s extracellular domain unknown despite previous attempts using X-ray crystallography and NMR spectroscopy. As a result, there knowledge gap regarding antigen presentation. This hinders production monoclonal antibodies (mAbs) against an...

capture elisa system was developed for diagnosis of visceral leishmaniasis (vl) using a monoclonal antibody raised against an antigen previously detected in the urine of vl patients. urine samples from confirmed vl cases from yemen, nepal, spain, sudan and brazil were tested in the capture elisa in comparison with urine samples from endemic and non-endemic areas along with urine samples from pa...

Abstract The Auchinleck Manuscript was produced in the 1330s London and is best known to scholars of Middle English literature on account romances that it transmits. Several these texts treat establishment defense England has been argued their interest history matched by language which almost all manuscript’s are written: English. This article reconsiders Englishness via a quantitative analysis...

Leukocyte trafficking involves specific recognition between P-selectin and L-selectin and PSGL-1 containing core 2-based O-glycans expressing sialyl Lewis x (SLe(x)) antigen. However, the structural identity of the glycan component(s) displayed by murine neutrophil PSGL-1 that contributes to its P-selectin counter-receptor activity has been uncertain, since these cells express little if any SLe...

Cytotoxicity of immunotoxins (ITs) varies considerably depending on factors like the capability of the target antigen to internalize IT molecules, intracellular processing and routing of the IT. We studied factors that may influence cytotoxicity of CD22-ricin A IT to several B cell lines. The antigen density varied from 5.9 x 10(3) to 6.0 x 10(4) molecules/cell. The ID50, determined by protein ...
