Automated Microscopy

The traditional microscope that you know and love is operated manually. Picture the scene: the microscopist chooses the light source, gently places the sample the moveable stage, selects the objective lens, and scans to select the field of view. This process is perfect for processing and analyzing a small number of samples per day. But…

How to Store Your Concentrated Proteins

Like graduate students, proteins are sensitive to rough handling. This is particularly true when they (the proteins, not the students!) are being concentrated, purified, and stored. We’ve covered the many options out there for concentrating your proteins, along with how to handle protein extracts to keep your proteins safe from degradation. But proteins can degrade…

How to Choose Quality Antibodies for Successful Western Blotting

Successful western blotting means achieving unambiguous results, and this requires a sensitive and specific antibody-antigen interaction. Consequently, high quality antibodies are critical for reliable and consistent western blotting. Western Blotting Process In the basic western blotting process, polyacrylamide gel electrophoresis (PAGE) separates a mix of proteins according to their molecular weights (denaturing gels) or their…

Top 5 of the most commonly used cell lines!

Cell lines are an invaluable scientific tool. They allow us to dissect the internal workings of tissues in a controlled environment without the ethical implications of working with whole organisms. Starting with the first successful immortal cell line HeLa, the number of available cell lines has since diversified into a plethora of options. Just like model…
