The gene for the human orthologue of mouse epiglycanin, a mucin expressed on mammary carcinoma TA3-Ha cells but not TA3-St cells, was identified by homology search to a mouse epiglycanin cDNA fragment identified by representational difference analysis between TA3-Ha and TA3-St cells. The open reading frame of this gene was cloned from human cervical carcinoma ME-180 cells. It consists of a muci...

Background: Transforming growth factor-β (TGF-β) in addition to the C-terminal region can phosphorylate receptor-regulated Smads (R-Smads) in their linker region. The aim of the present study was to evaluate the role of signaling mediators such as NAD(P)H oxidases (reactive oxygen species [ROS] generators), ROS, and ROS-sensitive p38 mitogen-activated protein kinase (p38MAPK) in this signaling ...

Recombinant human tumor necrosis factor alpha (rHuTNF-alpha) administered intravenously to mice resulted in enhanced resistance to a lethal challenge infection of Listeria monocytogenes given 24 h later. The observed protection was lost following treatment of the rHuTNF-alpha preparations with rabbit polyclonal antibody rHuTNF-alpha but not with normal rabbit immunoglobulin G.

rotavirus nonstructural glycoprotein nsp4 can induce diarrhea in newborn mice. it has been suggested that nsp4 may be a key determinant for rotavirus pathogenesis and a target for vaccine development. in order to study the biological and morphological role of nsp4 a large amount of the purified protein and antibody against it are required. simian rotavirus sa11 was propagated in bscl cell, puri...

Human respiratory syncytial virus (hRSV) and human metapneumovirus (hMPV), two members of the Pneumoviridae family, account for the majority of severe lower respiratory tract infections worldwide in very young children. They are also a frequent cause of morbidity and mortality in the elderly and immunocompromised adults. High levels of neutralizing antibodies, mostly directed against the viral ...

Human coronavirus HCoV-229E uses human aminopeptidase N (hAPN) as its receptor (C. L. Yeager et al., Nature 357:420-422, 1992). To identify the receptor-binding domain of the viral spike glycoprotein (S), we expressed soluble truncated histidine-tagged S glycoproteins by using baculovirus expression vectors. Truncated S proteins purified by nickel affinity chromatography were shown to be glycos...

UNLABELLED BACKGROUND Human kallikrein-related peptidase 6 (KLK6) has been implicated in various types of cancer and in neurodegenerative and demyelinating diseases including multiple sclerosis. Further, anti-KLK6 antibodies attenuated disease manifestations in the mouse model of multiple sclerosis. Availability of specific antibodies against KLK6 is fundamental to the development of improve...

BACKGROUND Introduction: GM2 is a type of ganglioside. It is associated with GM2 gangliosidoses such as Tay-Sachs disease.

Heterophilic antibodies interfere in two-site immunoassays. Our purpose was to screen for the samples containing heterophilic antibodies that react with mouse immunoglobulins and to use them to determine how to eliminate interference in various two-site immunoassays being developed in our laboratory. Of approximately 2600 samples screened, 81 had heterophilic antibodies. When creatine kinase MB...

Anti-Malassezia furfur monospecific polyclonal antibodies was produced by repeated immunization of rabbit with Malassezia furfur yeast cells mixed with Freud adjuvant. The antibody titres of respective rabbit's serum samples prior to and after each immunization against M. furfur were assayed by indirect immunofluorescence technique using the M. furfur whole yeast antigen fixed in Teflon coated ...
