Imaging Mycobacterium tuberculosis in Mice with Reporter Enzyme Fluorescence10:06

Imaging Mycobacterium tuberculosis in Mice with Reporter Enzyme Fluorescence

7.8K
We describe the optical imaging of mice infected with Mycobacterium tuberculosis (M. tuberculosis) using reporter enzyme fluorescence (REF). This protocol facilitates the sensitive and specific detection of M. tuberculosis in pre-clinical animal models for pathogenesis, therapeutics and vaccine...

Separation and Fractionation of Culture Filtrate Proteins (CFPs) from Mycobacterium tuberculosis08:48

Separation and Fractionation of Culture Filtrate Proteins (CFPs) from Mycobacterium tuberculosis

554
This protocol describes the culturing, harvesting, and concentration of secreted proteins of Mycobacterium tuberculosis. Culture filtrate proteins (CFPs) are quantified, separated into 20 fractions by isoelectric focusing, and further resolved into 30 fractions using a preparative SDS-PAGE and an electroelution system.

Fluorescence Assays for the Study of Mycobacterium tuberculosis Interaction with the Immune Receptor SLAMF107:42

Fluorescence Assays for the Study of Mycobacterium tuberculosis Interaction with the Immune Receptor SLAMF1

896
This study provides a protocol for evaluating the interaction of Mycobacterium tuberculosis with the SLAMF1 microbial sensor. The assays were conducted on human monocyte-derived macrophages using flow cytometry and fluorescence microscopy. The described tools are relevant for studying interactions between pathogens and...

An Experimental Model to Study Tuberculosis-Malaria Coinfection upon Natural Transmission of Mycobacterium tuberculosis and Plasmodium berghei09:02

An Experimental Model to Study Tuberculosis-Malaria Coinfection upon Natural Transmission of Mycobacterium tuberculosis and Plasmodium berghei

20.2K
Tuberculosis and malaria are two of the most prevalent infections in humans and major causes of morbidity and mortality in impoverished populations in the tropics. We established an experimental model system to study outcome of malaria-tuberculosis coinfection in mice after challenge with both pathogens via their natural route of...
