During the assay, a test compound is introduced to the apical chamber, and the permeation of the compound through the Caco-2 monolayer is monitored over time. Samples are collected from the basolateral chamber to measure the amount of compound that has permeated. ...
Latex Agglutination Assays: The Role of Dyed Polystyrene Particles Latex agglutination is the change in agglutination capacity observed when a sample containing a specific antigen is mixed with antibodies coated on the surface of latex particles. Agglutination can also be reversed by coating latex particles with specific antigens and testing the sample for the ...
As the new year begins, many people prioritize their health by scheduling annual physicals and medical check-ups. While these routine exams ensure overall well-being, few realize the crucial role that fluoropolymers play in modern medical technology. From diagnostic tools to life-saving devices, fluoropolymer materials contribute significantly to patient safety, hygiene, and the accuracy of ...
Unveiling the Process: Key Stages Sample Collection: Precision in collecting samples from the primary infection site augments detection rates substantially. Sample Pre-Treatment: Different samples necessitate distinct pre-treatment strategies—liquefaction for sputum, dewaxing for FFPE ...
We discuss the benefits that this software has brought to his laboratory with Dr Kevin Lindsay, Principal Clinical Scientist, of the Andrology Department at London’s Hammersmith Hospital NHS Trust. Many priceless collections of samples are entrusted to simple ‘pen and paper’ systems with all the obvious risks that entails. ...
On day 14, a booster dose was administered and serum samples were collected on day 28. Antibody levels were significantly increased in a dose-dependent manner, with GMT values up to 19118 (2 μg) and 181875 (10 μg). ...
Methods: 151 women with risk factors for or clinical signs and symptoms of preeclampsia were selected from a prospective cohort. Maternal serum samples were collected between 20 and 37 weeks of gestation. Clinical suspicion of preeclampsia was defined as presence of new-onset proteinuria, or clinical symptoms of preeclampsia. ...
The remote blood collection technology needed to be easy for subjects to use, quick to deploy, and produce a stable clinical-grade sample. Further, overall user experience needed to be positive in order to encourage completion of the multiple blood collection timepoints required. “The nature of the studies we are performing—which ...
Metabolomics presents several challenges that must be addressed to ensure reliable and reproducible results: Sample Complexity: Biological samples used in metabolomics, such as blood, urine, tissues, or cells, are inherently complex. ...
The process of 16S/18S/ITS amplicon sequencing entails DNA extraction from environmental samples, careful selection of universal primers to amplify the target region of 16S/18S/ITS, and the subsequent detection of sequence variations and abundance in the target region. ...
Check back for our next installment, in which we analyze transcriptomics from spinal cord samples collected from patients as well as a mouse model. In this post, we will continue to explore publicly available datasets surrounding Amyotrophic Lateral Sclerosis (ALS), a devastating neuromuscular degenerative disease for which there is no cure. ...

Since the 19th century, the practice of tissue processing has remained largely unchanged, resulting in solidified, paraffin-embedded tissue blocks for sectioning. As staining procedures have advanced and immunohistochemistry is becoming more widely used, high-quality tissue sections are paramount for accurate interpretation of disease ...
This blog post introduces the concept of collections: a user-defined collection of projects that allows projects and samples to be organised and analysed at the cohort level. We will briefly look at how we can collect projects together and perform quality control (QC) of sample data. These QC tasks are typically ...
The TB Breathalyzer, patented by Rapid Biosensor Systems, consists of a plastic cough sample collection tube (10 cm in length and 3.5cm in width) containing a bio-optical sensor covered in a patented bio-chemical coating formulated to react with the TB bacilli. ...
A 2020 study confirmed B. quintana DNA in 19.3% of dental samples collected from nine archeological sites that spanned 1900 years. ...
Highlights Viable Delta Variant SARS-CoV-2 collected from air samples in a residential environment. SARS-CoV-2 detected in an area of a single-family dwelling distant from an isolation suite occupied by COVID-19 patient. ...
Thus, high-resolution microbiome analysis needs to be performed at a much greater sampling depth to determine strain-level population structures and dynamics relevant to ecology and epidemiology and for public health interventions. Whole genome sequencing (WGS) has been introduced sporadically in oral microbiome research because the low number of samples from the ...
In response to the experts' questions, Kostrikis stated on January 9 that the emergence of Deltacron is not a single recombination event, but rather a mutation that evolved as a result of adaptation to its environment, and that the collected samples were tested not only in Cyprus but also in laboratories in other countries, and that Deltacron recombination was ...
In Kenya, Kurtis set out to apply the same principle. As he took blood samples from children, he noted that some seemed particularly susceptible to malaria, given the number of times they’d gotten the disease; others seemed resistant. ...
