  Partially fed (4 -5 days) H .a. anatolicum (Iranian isolate) female adult ticks were used for preparation of antigens of midgut which are, the gut supernate antigen (GS), gut membrane antigen (GM), triton extracted gut membrane antigen ( TX-GM ) and sodium dodecyl sulphate treated Triton extracted gut membrane antigen (SDS-TX-GM). The New Zealand white rabbits were immunized with GS, GM, TX- ...

This report describes a procedure by which high performance liquid chromatographic (HPLC) techniques are used to obtain homogeneous S-antigen. Conventionally prepared S-antigen was purified further by fractionation on the anion exchange Mono-Q column followed by gel filtration on a TSK-3000 column. This procedure produced an S-antigen preparation, which appeared homogeneous by gel electrophores...

PURPOSE To clarify the differences in prognosis of colorectal cancer patients based on the expression of sialyl Lewisaa sialyl Lewisx and sialyl Tn antigens in serum and tumor tissue. PATIENTS AND METHODS Preoperative serum levels (by radioimmunoassay) and tumor tissue expression (by immunohistochemistry) of these antigens were simultaneously determined in 52 patients. For each antigen, patie...

in this study which has been carried out from 1996 until 1997 soluble latex agglutination antigen was prepared from L, donovani,sudan(s-1) by culturing in special media,harvesting,and later solubilizing by freezing and thawing.the antigen were futher prepared by high speed centrifugation.after measurement of the protein (lowry method) concentration of the antigen was set at 2.2 mg/ml,the antige...

The morphology of S-antigen-induced uveoretinitis in guinea pigs has been studied using transmission electron microscopy. Purified bovine retinal S-antigen was shown to produce a focal chorioretinitis, characterized by selective damage to the outer retina and, almost exclusively, a mononuclear cell infiltration of the choroid and retina. Even at high doses, extensive rod outer segment damage wa...

We established a monoclonal antibody against a surface antigen of activated macrophages (Møs) involved in the rejection of an allografted mouse tumor, Meth A. Bacteria-elicited Møs also expressed the antigen but resident or inflammatory Møs, or other leukocytes, did not. The antigen was identified as Ly-6C by isolation of cDNA clones encoding it. Two-dimensional immunoblotting revealed that Ly-...

The hepatitis delta virus (HDV) is coated with large (L), middle (M), and small (S) envelope proteins encoded by coinfecting hepatitis B virus (HBV). To study the role of the HBV envelope proteins in the assembly and infectivity of HDV, we produced three types of recombinant particles in Huh7 cells by transfection with HBV DNA and HDV cDNA: (i) particles with an envelope containing the S HBV en...

BACKGROUND An enzyme-linked immunosorbent assay (ELISA) and indirect immunofluorescence assay (IFA) were evaluated for serological diagnosis of human strongyloidiasis. METHODS Serum specimens obtained from 46 individuals infected with Strongyloides stercoralis, 37 healthy persons and 381 persons with other parasitic infections were tested using an IgG-ELISA that used crude antigen of S. sterc...

Hybrid cell clones between mouse cells deficient in thymidine kinase (EC 2.7.1.21) and two different human cell lines transformed by simian virus 40 (SV40) and deficient in hypoxanthine phosphoribosyltransferase (EC 2.4.2.8) were examined for SV40 tumor (T) antigen(s). Concordant segregation of the gene(s) for SV40 T antigen and human chromosome C-7 was observed in these hybrids. The human chro...
