Protein Standards Increase HPLC Accuracy
A newly launched library of more than 5,000 human proteins is desinged for increased accuracy in high performance liquid chromatography and mass spectrometry analyses, according to life sciences company OriGene Technologies.
A newly launched library of more than 5,000 human proteins is desinged for increased accuracy in high performance liquid chromatography and mass spectrometry analyses, according to life sciences company OriGene Technologies.
The company has released a library of heavy isotope labelled human proteins to serve as international standards for mass spectrometry analyses featuring single reaction and multiple reaction monitoring (MRM). According to the company, the aim is to produce research tools that allow for disease mechanisms to be researched and drugs to be developed based across the entire human genome, with stem cell research and cancer as two areas of particular interest.
“Mass spectrometry - especially MRM - has emerged as a new platform for quantitative characterisation of multiple proteins, thus making it an ideal choice for high-throughput proteomics and clinical biomarker research,” the company stated in a press release.
Characterizing Plant Polysaccharides Using Size-Exclusion Chromatography
April 4th 2025With green chemistry becoming more standardized, Leena Pitkänen of Aalto University analyzed how useful size-exclusion chromatography (SEC) and asymmetric flow field-flow fractionation (AF4) could be in characterizing plant polysaccharides.
Investigating the Protective Effects of Frankincense Oil on Wound Healing with GC–MS
April 2nd 2025Frankincense essential oil is known for its anti-inflammatory, antioxidant, and therapeutic properties. A recent study investigated the protective effects of the oil in an excision wound model in rats, focusing on oxidative stress reduction, inflammatory cytokine modulation, and caspase-3 regulation; chemical composition of the oil was analyzed using gas chromatography–mass spectrometry (GC–MS).
