Separation of soluble Brucella antigens by gel-filtration chromatography.

Mouse Isoantigens: Separation of Soluble Tl (thymus-leukemia) Antigen from Soluble H-2 Histocompatibility Antigen by Column Chromatography

Mouse H-2 histocompatibility antigen has been extracted, solubilized, and partly purified from the cells of an A strain spontaneous leukemia carrying TL (thymus-leukemia) antigens. H-2 and TL. 1, 2, 3 activities were measured by inhibition of the cytotoxic effect of the corresponding isoantibodies. TL activity was associated with the H-2 active fraction obtained by solubilization and fractionat...

Separation of antigens of Streptococcus faecalis by gel filtration.

تخلیص و ارزیابی آنتی ژنهای اصلی مایع هیداتیک در تشخیص ایمونولوژیک هیداتیدوز

    Regarding remarkable prevalence of human hydatidosis and despite introduction of novel sensitive techniques such as ELISA for immunodiagnosis of disease in the word, there has not been much progress in that field in Iran. Preparation and purification of suitable antigens is the basic and first step in serodiagnosis of this disease. The present study, thus, is designed and carried out for pr...

Expression and Purification of Brucella-Specific Nanobodies

Background: Brucellosis is still considered as one of the major zoonosis afflicting Syrian health and economy. This disease is caused by members of the genus Brucella which are gram-negative bacteria living facultatively within mammalian cells during infection. Objectives: In this paper, a strategy was developed to introduce a new generation of binders called Nanobodies (Nbs) in our combat aga...

Virion and soluble antigens of japanese encephalitis virus.

Japanese encephalitis virions contain a 58 X 10-3-molecular-weight envelope glycoprotein antigen that can be solubilized with sodium lauryl sulfate and separated from other virion structural polypeptides and viral ribonucleic acid by gel filtration chromatography. The 58 X 10-3-molecular-weight envelope protein is the major antigen responsible for cross-reactivity of the virion in complement fi...
