Label-free microfluidic detection of low-concentration DNA
Proteomics-based identification and resistance detection of ESKAPE pathogens
Antimicrobial resistance (AMR) makes treating bacterial infections increasingly difficult, and current diagnostics rely on separate methods for antimicrobial susceptibility testing and species identification. Researchers at the @Robert Koch Institute evaluated a proteomics-based workflow that can identify bacterial species and predict AMR phenotypes from primary cultures within about two hours. The NanoPhotometer® NP80 was used to quantify bacterial protein concentration, then used again downstream to quantify peptides after protein digestion with trypsin. Testing 126 clinical isolates across 16 species showed high performance, with 100% specificity and 94.4% sensitivity for AMR detection. The findings suggest that proteomics could become a powerful diagnostic tool in clinical microbiology by enabling rapid, accurate bacterial phenotyping in a single measurement.

A molecular basis for flower color variation
Spring has arrived – the season for new beginnings, discovery, and advancement 🌻
A 2024 study investigates the molecular basis of flower color variation in Iris sanguinea using a combined multi-omics approach. The researchers found that differences in petal color are attributed to the accumulation of anthocyanin pigments, which is driven by the differential expression of genes involved in the flavonoid biosynthesis pathway. The researchers used a NanoPhotometer® to assess RNA quality. Overall, the study provides a gene-metabolite framework explaining flower coloration and offers insights into ornamental plant breeding and genetic improvement.

Fasting Alters Igf1 Signaling Pathways and Growth Regulation in Rockfish
In a study published in General and Comparative Endocrinology, researchers at @California Polytechnic State University investigated the effect of nuritional stress on the sensitivity of liver Igf1 synthesis pathways to growth hormone. The NanoPhotometer P300 was used to quantify total RNA extracted from liver and skeletal muscle tissues of fed and fasted rockfish.
Total RNA was used for downstream qRT-PCR to determine relative liver and skeletal muscle mRNA expression. Overall, the findings suggest that growth hormone/Igf1 signaling and growth regulation is altered by food limitation.
