Molecular characterization of multivalent bioconjugates by size-exclusion chromatography with multiangle laser light scattering.
The degree of substitution and valency of bioconjugate reaction products are often poorly judged or require multiple time- and product-consuming chemical characterization methods. These aspects become critical when analyzing and optimizing the potency of costly polyvalent bioactive conjugates. In this study, size-exclusion chromatography with multiangle laser light scattering was paired with re...
متن کاملSimultaneous Calibration of Size Exclusion Chromatography and Dynamic Light Scattering for the Characterization of Gelatin
A novel method of calibrating size exclusion chromatography (SEC or known as GPC) and dynamic light scattering (DLS or known as QELS or PCS) is proposed for the characterization of gelatin. A conventional calibration of SEC or DLS normally requires a set of narrowly distributed gelatin standards with different molecular weights. By contrast, the new method uses only one broadly distributed gela...
متن کاملCharacterization of Whey Protein Isolate (WPI) using multi-detector size-exclusion chromatography
Whey protein Isolate is of high nutritional value, and has become an important source of functional ingredients in various health-promoting foods. It is widely used in infant formula to provide a natural source of amino acids for optimal growth and development, and is also often used as an emulsifier and stabilizer in the food industry. WPI is also popular among athletes because of its ability ...
متن کاملUtilization of an evaporative light scattering detector for high-performance size-exclusion chromatography of galacturonic acid oligomers.
A high-performance size-exclusion chromatography-evaporative light scattering detector method was used to separate, detect and quantify galacturonic acid (GA) oligomers. In 40 mM acetic acid GA monomer, dimer and trimer could be separated with baseline resolution but polygalacturonic acid (PGA) precipitated and could not be eluted from the column. An NH4OAc, pH 3.7, buffer was developed as the ...
متن کاملSize and conformation of Ficoll as determined by size-exclusion chromatography followed by multiangle light scattering.
The characteristics of the glomerular filtration barrier (GFB) are challenging to measure, as macromolecular solutes in blood may be metabolized or transported by various cells in the kidney. Urinary solute concentrations generally reflect the cumulative influence of multiple transport processes rather than the intrinsic behavior of the GFB alone. Synthetic tracer molecules which are not secret...
