Tosoh Product Profile
Tosoh Bioscience presents a new brochure featuring the use of TSKgel columns for SEC with aqueous mobile phases, also known as gel filtration chromatography (GFC). The brochure comprises all aspects of SEC, starting with the fundamentals of SEC, characteristics of TSKgel SEC columns, and application examples for the different column types:
Silica based TSKgel SW columns are the industry’s standard for the separation of proteins by aqueous SEC. TSKgel SuperSW columns have smaller diameters and are filled with smaller particles. Providing both, high sensitivity and high resolution, they are ideally suited for the QC of low dose biopharmaceuticals.
The brochure also features the latest additions to the polymer based SEC columns, such as the TSKgel PWXL-CP columns for the analysis of cationic polymers and the TSKgel SuperMultiporePW linear SEC columns, deigned to determine the size distribution of water soluble polymers, such as polyvinylpyrrolidones or dextrans.
The brochure supports users in selecting the appropriate column and gaining the best SEC performance.
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).
