1. Glutathione transferases from the liver, lung and kidney tissues of the buffalo (Bubalus bubalis) and the Kedah-Kelantan cattle (Bos indicus) were partially purified by ammonium sulphate precipitation and Sephadex G-75 gel filtration. 2. Liver tissue contains the highest enzyme activity when compared to the lung and kidney tissues. 3. The activity in cattle is higher than that in the buffalo. 4. Isoelectric focusing separates the activities into the acidic, near neutral and basic fractions. 5. The focused patterns are different for each of the tissues and in each of the species investigated.

Background: Hemoglobin (Hb) Hekinan is a prevalent α-globin variant frequently missed in thalassemia screening centers using high-performance liquid chromatography (HPLC) or capillary electrophoresis. This study aims to investigate the hematological and molecular characteristics of Hb Hekinan in a large cohort.
Methods: Hb variants were identified using isoelectric focusing (IEF) and HPLC.

Background: CSF (cerebrospinal fluid) oligoclonal immunoglobulin G bands (IgG-OCBs) analysis plays a crucial role in diagnosis of various neurological disorders. However, the clinical significance of mirror pattern bands remains unclear, and their precise application is not well understood.
Methods: We retrospectively reviewed a total of 7597 IgG-OCB records detected using isoelectric focusing from May 2020 and August 2023 at Huashan Hospital.

A significant limitation of imaged capillary electric focusing (icIEF) is the inability to identify and characterize specific species in the electropherogram. This has led to the development of complementary ion-exchange chromatography (IEX)-based methods that are amenable to either fraction collection and subsequent characterization or online IEX coupled to mass spectrometry. To overcome this limitation while maintaining the use of icIEF, novel approaches, including an icIEF separation and fractionation technology (MauriceFlex, ProteinSimple), have been developed.

Characterizing major bovine milk proteins, including whey and casein, is of significant interest in the dairy industry. The diverse array of protein proteoforms can be different in terms of genetic variation, breed ways, lactation stage, and animal nutritional status. Current routine methods for bovine milk protein profiling are typically based on immunological techniques, infrared spectroscopy, slab gel isoelectric focusing, capillary electrophoresis, and high-performance liquid chromatography.

Background And Aims: Recently, demands towards identifying various molecules in support of stress detection and potential clinical utilization are dramatically increasing. Moreover, the accuracy with which researchers quantify these informative molecules is now far more improved when compared to the past. As RNA or protein markers are conventionally detected via repeated invasive procedures from blood, it is critical to develop secure technologies to obtain the desired information via less stressful methodologies, such as saliva collection.
