Antibody Selection for Immunohistochemistry

Posted by The Protein Man on Mar 26, 2019 1:18:00 PM

Antibodies have become a great tool for identifying and characterization of different proteins in different model systems using the technique of immunohistochemistry and Western blotting. The precision and sensitivity of these molecules allow us to develop a clear-cut picture of molecular cascades and signalling pathways. The technique of characterization of proteins by immunohistochemistry is very old, however it requires elaborate standardization and rigorous scientific approach to select the right antibodies for the experimental need.

A Guide to Sample Preparation for Immunofluorescence

Posted by The Protein Man on Mar 12, 2019 2:30:00 PM

Immunofluorescence is an essential and a powerful tool in molecular biology for the visualization of cellular structures, protein localization and intracellular processes. The resultant sample produced after immunofluorescence is analyzed using different microscopic methods such as confocal microscopy, epifluorescence, TIRF, or GSDIM depending on the experiment.
