Metric Options: Counts1 Year3 YearSelecting the 1-year or 3-year option will change the metrics count to percentiles, illustrating how an article or review compares to other articles or reviews within the selected time period in the same journal. Selecting the 1-year option compares the metrics against other articles/reviews that were also published in the same calendar year. Selecting the 3-year option compares the metrics against other articles/reviews that were also published in the same calendar year plus the two years prior.
Example: if you select the 1-year option for an article published in 2019 and a metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019. If you select the 3-year option for the same article published in 2019 and the metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019, 2018 and 2017.

Article Description
Specific mycobacterial antigens are an important prerequisite in the serodiagnosis of tuberculosis. Many studies have reported the use of both native and recombinant proteins. Even though recombinant proteins can form standardized reagents with unlimited supply, their diagnostic test characteristics were not satisfactory in some cases. In this study we have purified the 38-, 30- (antigen 85B), and 16-kDa native antigens of Mycobacterium tuberculosis by procedures with limited number of steps. Starting with the secreted antigens of M. tuberculosis H37Rv, the 38-kDa form was purified by preparative isoelectric focusing, followed by preparative electrophoresis. Separation of antigen 85 components was achieved by anion-exchange chromatography, followed by hydrophobic interaction chromatography. Gel-permeation chromatography was employed for the isolation of the 16-kDa form, from the cytosol fraction of M. tuberculosis H37Rv. By using a minimal number of steps, considerable yields of these proteins were obtained without loss of immunological activity. The native proteins purified were characterized by analytical two-dimensional electrophoresis, HPLC, and circular dichroism studies. Conformation of the native 38-kDa form purified in our laboratory was different from that of the recombinant 38-kDa form from the WHO Bank. The identities of these native antigens were established by immunoblotting with known monoclonal antibodies from the WHO Bank.
