Antibodies continue to be extremely utilized entities in myriad applications including basic research, imaging, targeted delivery, chromatography, diagnostics, and therapeutics. At production stage, antibodies are generally present in complex matrices and most of their intended applications necessitate purification. Antibody purification has always been a major bottleneck in downstream processing of antibodies, due to the need of high quality products and associated high costs. Over the years, extensive research has focused on finding better purification methodologies to overcome this holdup. Among a plethora of different techniques, affinity chromatography is one of the most selective, rapid and easy method for antibody purification. This review aims to provide a detailed overview on affinity chromatography and the components involved in purification. An array of support matrices along with various classes of affinity ligands detailing their underlying working principles, together with the advantages and limitations of each system in purifying different types of antibodies, accompanying recent developments and important practical methodological considerations to optimize purification procedure are discussed.

Background: Homozygosity for the rare APOE3-Christchurch (APOE3Ch) variant, encoding for apoE3-R136S (apoE3-Ch), was linked to resistance against an aggressive form of familial Alzheimer's disease (AD). Carrying two copies of APOE3Ch was sufficient to delay autosomal AD onset by 30 years. This remarkable protective effect makes it a strong candidate for uncovering new therapies against AD.

Objectives: To investigate the phytochemical composition of Ajwa date extract and evaluate its antiviral activity and mechanism of action.
Methods: High perfomance liquid chromatography, gas chromatography-mass spectrometry, and liquid chromatography-mass spectrometry were used to analyze the phytochemical profile of Ajwa date extract. The antiviral activity was assessed using the MTT colorimetric assay against herpes simplex virus type I (HSV-I) and coxsackievirus B4 (CVB-4).

The interaction between proteins and aroma compounds significantly impacts cheese flavor retention during processing. However, it is still unknown how cheese proteins and the aldehyde aroma compounds (AACs) interact. This study aims to clarify the interaction mechanisms between the AACs (benzaldehyde, 2-methylpropanal, 2-methylbutanal and 3-methylbutanal) and β-casein (β-CN) using SPME-GC/MS, multi-spectroscopy techniques, and molecular dynamics simulations.

Adeno-associated virus (AAV) vectors have become a leading platform for gene delivery. A major portion of gene therapy currently in clinical trials are AAV-based for a wide range of diseases. A commonly used method for AAV production is by mammalian or insect cell culture, with or without added viruses to introduce needed genetic elements for AAV production.
