Polymerase chain reaction (PCR) is one of the most widely used techniques among biomedical researchers, forensic scientists, and medical laboratory professionals. It’s employed for genotyping, sequencing, cloning, and gene expression analysis to name only a handful of its applications. Labeling PCR tubes and strips is no easy feat, however; they are relatively small, providing little space for information, while skirted quantitative PCR (qPCR) plates can only be labeled on their side.
So, you’ve decided to make the switch to a thermal-transfer barcode printer. Whether this is because your label printout keeps smearing due to chemical exposure or your having difficulty scanning your barcodes, there are some key factors you can expect to encounter when making the switch from laser to thermal-transfer printing.
Repetitive stress injury (RSI) is a serious condition that’s frequently associated with lab work. The daily routine of pipetting and other repetitive movements can lead to tissues, like muscles, tendons, and ligaments, wearing down. The resulting picture isn’t bright: chronic pain, aches, cramping, swelling, tingling, and numbness are just some of the symptoms of RSI. Some even suffer from full-blown RSI-associate syndromes, like carpel tunnel syndrome, tendonitis, or tenosynovitis (inflammation of the fluid-filled sheath around the tendon).1
The definition of LIMS is ever-evolving, with the technology used to develop it continually advancing and the needs of laboratories frequently changing. What remains constant, however, is the need to streamline sample tracking and traceability, data collection, and report generation. This is a continual pressing concern for the managers of academic, clinical, pharmaceutical, and biotechnology labs, which are always looking for new solutions. LIMS was created to help fulfill these needs by automating the reporting process, managing data and inventory, monitoring workflows, assigning tasks, and storing data.
Everyone, at some point in their scientific career, has come across a technique that is made far more difficult than necessary because of how difficult it is to label their samples. However, whether your labels keep falling off, or the ink is continually smudging or fading, there’s usually an efficient solution to the problem. Below, we’ve listed several of the top experimental techniques that drive scientists crazy when it comes time to label tubes and slides.
Errors are difficult to avoid completely, no matter where you work. However, these errors can be especially costly to an assisted reproductive technology/in vitro fertilization (ART/IVF) clinic. With large numbers of donor egg and sperm samples as well as embryos that need to be accounted for on a daily basis, mistakes must be avoided at all costs. Here, we’ll discuss some of the methods IVF clinics have implemented to reduce or outright eliminate mistakes.
Keeping a productive lab running smoothly isn’t an easy thing to do. Below, we’ve listed several tips that can set your lab up for continued success, whether your grant deadlines are fast approaching or you’re dealing with an inordinate number of samples.
In vitro fertilization (IVF) is a common technique utilized by assisted reproductive technology (ART) facilities to fertilize donor eggs, and implant them back into the mother. In addition to performing IVF, these clinics frequently store eggs, sperm, and embryos. Unfortunately, manipulating these cells outside of the human body means they are exposed to many types of airborne pollutants, including volatile organic compounds (VOCs). Though embryos are considered extremely adaptable cells, exposure to VOCs can induce changes in gene expression and regulation, including imprinting and epigenetic alterations, which may affect the outcome of IVF procedures.
Throughout the last several years, scientists have been debating whether there is a reproducibility crisis in biomedical research. It’s no surprise: how often are you able to repeat the exact results of your own experiments, let alone those from another lab? Sure, there’s a certain amount of variability given the nature of complex cellular systems. However, if the idea is to use these findings for something bigger, then reproducing results is critical. So, why does it appear that results can’t be corroborated very frequently? And how big of an issue is it really?
Lab fails happen to the best of us. We started a contest to commemorate the veterans who have experienced these traumatic or hilarious moments. You all sent us your best work, and we’re happy to announce the winners here, in our blog. These lucky people will receive both the distinction of having the best (worst?) lab fail of the month as well as a stylish GiantMicrobes DNA plushy. Without further ado, here are your best lab fails of March 2019:
