Paracoccidioides brasiliensis antigen batches from the same isolate show immunological and biochemical differences
(1996-12-01)
We investigated the occurrence of antigenic and biochemical variability among Paracoccidioides brasiliensis antigen batches prepared according to the same protocol. Initially (experiment 1), we analyzed two antigen lots ...
Identification of cytoplasmic soluble antigens related to the major surface antigens of Leishmania braziliensis braziliensis and L. donovani chagasi
(Parasitol Res., 1990)
Abstract. This study describes the identification of aqueous-soluble antigens in Leishmania promastigotes immunologically and biochemically closely related to the major surface antigen. Proteins from surface-iodinated L. ...

Enzymatic Hydrolysis of Sweet Lupin, Chickpea, and Lentil 11S Globulins Decreases their Antigenic Activity
(Amer Chemical Soc, 2009-02-11)
We investigated the effects of treatments with the enzymes pepsin and trypsin on the in vitro immunological reactivity of the major globulins found in the seeds of sweet lupin, chickpea, and lentil. Polyclonal major ...
Distinct localization of T cell Agrin during antigen presentation - evidence for the expression of Agrin receptor(s) in antigen-presenting cells
(Wiley-Blackwell, 2012-07-01)
Agrin is over-expressed by activated and autoimmune T cells, and synergizes with the T cell receptor (TCR) to augment cell activation. In the present study, we show that Agrin accumulates to distinct areas of the plasma ...

Effects of tunicamycin on glycoprotein antigens of Aspergillus fumigatus
(1996-12-01)
Tunicamycin, which inhibits N-glycosylation of proteins, was used as a tool to determine the type of linkage which occurs in glycoprotein antigens of Aspergillus fumigatus. When A. fumigatus extracts were electrophoretically ...
