Interested in the detailed structure of your tissue? High-resolution imaging techniques, such as brain electron microscopy, provide an intricate view of your tissue. While it may be a rather complicated procedure with nasty chemicals, the advantages of epon embedding can make it the best choice for morphological studies. The hard blocks are excellent for structural…
In the first part of this series, we discussed the differences between a color and a monochrome microscope camera and when one is advantageous over the other. We also touched on the subject of optimal camera resolution for a given imaging system. In this part, we will tackle a few additional camera specifications and how…
If you remember from one of my previous articles (if not, you can read it here!), we introduced ‘fluorophores’. These are basically substances (natural or synthetic) which have the ability to absorb light at a low wavelength and re-emit at a higher wavelength. In other words- they fluoresce! In this article, I’ll introduce the three…
Most of the microscopes you will encounter in your laboratories will be ‘upright’. In other words, they are assembled (from top to bottom) in the order of; eyepieces, objectives (on revolving nosepiece), stage, sub-stage condenser, diaphragm and base. However, there are two other types of light microscopes you will perhaps encounter (and use) and it…
How you fix your tissue or cells can affect your results, for better or for worse. Discover the key points to think about before undertaking your histology fixation.
What Is Optical Mapping and How Is It Used? Synchronisation of the contraction of heart muscle is essential for the efficient pumping of blood through the circulatory system. Cardiac contraction is controlled by the regulated spread of electrical impulses from cell-to-cell within the heart. In pathological conditions, these electrical impulses can become disordered and lead…
