Preparation, Purification, and Stability of Tuberculin.

Development of Palladium-Alloy Membranes for Hydrogen Separation and Purification

This paper summarizes R&D activities and progress at NORAM Engineering and the University of British Columbia (UBC) on preparation and testing of thin palladium-based membranes and their applications. Most of these activities were carried out internally at NORAM, some jointly with UBC and their spin-off company, Membrane Reactor Technology (MRT) through a wide range of projects. Key results out...

A Method for Coupling Protein Antigens to Erythrocytes

A serological technique, using formalinized red cells coupled to tuberculin PPD as antigen, has been assayed in a trial series of 124 tuberculous and 139 non-tuberculous patients. The stability of the antigen preparation, and the omission of an adsorption procedure for the removal of isoagglutinins facilitated the performance of the test. The results indicate that the technique warrants further...

Preparation and biological study of 68Ga-DOTA-alendronate

Objective(s): In line with previous research on the development of conjugated bisphosphonate ligands as new bone-avid agents, in this study, DOTA conjugated alendronate (DOTA-ALN) was synthesized and evaluated after labeling with gallium-68 (68Ga).Methods: DOTA-ALN was synthesized and characterized, followed by 68Ga-DOTA-ALN preparation, using DOTA-ALN and 68GaCl3 (pH: 4-5) at 92-95°C for 10 mi...

ارزیابی کارایی پروتئین A60 باکتری مایکوباکتریوم بوویس سویه BCG به عنوان پادگن تشخیصی

     Tuberculosis is the most common infectious diseases. Current diagnostic methods are either slow or lack enough sensivity or specificity. Several mycobacterial antigens are involved in the complex interaction with the immune system of the host. They can be helpful for mycobacteria diagnosis. Antigen 60 (A60) is thermostable antigen found in Mycobacterium bovis and Mycobacterium tuberculosis...
