Pushing PCR to More Places - More products for the polymerase chain reaction make it ever easier to apply this technology

When Cary Mullis came up with the polymerase chain reaction (PCR) in 1983, it might have been hard to imagine how ubiquitous this technique would become in research and clinical labs. PCR is “a common laboratory technique used to make many copies (millions or billions!) of a particular region of DNA,” according to an article on the Khan Academy website. “For instance, DNA [...]

Go with the Flow for Less - To study thousands of cells more economically, just pick the right supplies.

Flow cytometry simultaneously analyzes a cell in many ways. The features analyzed can include cell size and number, plus molecular markers and other characteristics. Some instruments can analyze a couple dozen or more parameters of a cell. What’s more, 10,000 or more cells can be analyzed every second. So, flow cytometry provides high-content and high-speed results.For an overview of flow cytometry, [...]

Pictures in Pixels - Sensor options and accessories make all the difference in building the best setup for fixed or live-cell digital imaging

Making microscope images is fundamental to biological and clinical sciences. It’s one thing to see something amazing under a microscope and another to capture that image for further analysis or even just for the wow factor. Instead of shooting rolls of 35-millimeter film, today’s scientists - and those for the past couple decades now - rely on digital methods. Moving [...]

Sizing Up DNA Ladders - These molecular rulers reveal the size of nucleotide fragments

A Penn State website notes that DNA ladders “are among the most commonly used reagents in molecular biology research.” Also known as DNA molecular weight markers, scientists use these reagents to measure the size of fragments composed of nucleotides. That makes DNA ladders as important to a molecular biologist as a tape measure is to a carpenter. In other words, you [...]

Storing and Sending Slides -The Right Storage Container or Mailer Makes All the Difference

Microscope slides make up one of the most common items in many, many labs. In forensics, healthcare, life sciences and other areas, scientists and technicians often prepare microscope slides. In fact, labs easily make so many slides that deciding what to do with them becomes a challenge. In addition, the increase in collaborative projects, often involving scientists in various countries, drives the [...]

Preventing Painful Pipetting - Ergonomic Devices Avert Unnecessary Injuries in the Lab

Pushing a pipette too often over too much time can turn lab work into rehab. Despite being a known risk in labs for decades, this problem continues. In 1997, for example, David Buckle of the University of Surrey in the UK reported  in Applied Ergonomics that 90% of people tested complained of hand pain after just an hour of pipetting. With [...]

Controlling Pesticides in Cannabis - QuEChERS and other methods simplify the analysis

Keep cannabis clean! That could be one cry heard nearly around the world, and it means keeping as many chemicals, such as pesticides, out of cannabis-based products as possible. As cannabis gains access to more markets—medicinal and recreational—around the world, increasing regulations from governments must be met. Many of these regulations impact pesticides in cannabis. To meet those mandates, suppliers and manufacturers must [...]
