Multidimensional separation prior to mass spectrometry: Getting closer to the bottom of the iceberg [PDF]
, 2013 While prefractionation has previously been shown to improve results in MS analysis, a novel combination provides an additional dimension of separation: protein fractionation by SDS-PAGE followed by IEF of tryptic peptides before separation by RP-LC ...

Validation of isoelectric focusing method for recombinant erythropoietin detection in human urine
Saúde & Tecnologia, 2015 Erythropoietin (EPO) is a substance that stimulates red blood cell production, increasing muscle oxygenation and is secreted naturally by the body and excreted in urine in low concentrations.

Endogenous mammalian lectin localized extracellularly in lung elastic fibers. [PDF]
, 1984 An affinity-purified antibody preparation raised against a beta-galactoside-binding lectin from bovine lung was used to localize a similar lectin in rat lung by immunofluorescence and by electron microscopy after on-grid staining visualized with ...

Detecting β-Casein Variation in Bovine Milk
Molecules, 2016 In bovine species, β-casein (β-CN) is characterized by genetic polymorphism. The two most common protein variants are β-CN A2 (the original one) and A1, differing from A2 for one amino acid substitution (Pro67 to His67).

Effects of Biological Sex and Age on Cerebrospinal Fluid Markers—A Retrospective Observational Study
Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objective Cerebrospinal fluid (CSF) analysis is a key diagnostic tool for neurological diseases. To date, only a few studies have investigated in larger cohorts the effect of age and biological sex on diagnostic markers extracted from CSF. Methods For this retrospective observational study, 4163 CSF findings (2012–2020) were evaluated.

Advanced Functional Materials, EarlyView.For the first time, a highly sensitive electrochemical biosensor based on SiO2‐based hairy particles with a grafted PDMAEMA polymer brush containing a quantifiable and large amount of immobilized Laccase is reported. The fabricated biosensor exhibits a sensitivity of 0.14 A·m⁻¹, a limit of detection (LOD) of 0.1 µm, and a detection range of 0.3–750 µm,
