The technique of gel electrophoresis is now firmly established as a routine laboratory method for analyzing DNA. Here, we describe the development of the methodology as well as a brief explanation of how the technique works. There is a short introduction to pulsed-field agarose gel electrophoresis, which represents a critical advancement in the method that facilitates the analysis of very large fragments of DNA. Finally, theoretical considerations are included.

Significant progress has been made in the last two decades in producing small (<2μm), high-purity, and low-adsorption particles, columns and system hardware, for ultra-high pressure liquid chromatography (UHPLC). Simultaneously, the recent rapid expansion of cell and gene therapies for treating diseases necessitates novel analytical technologies for analyzing large (>2 kbp) plasmid double-stranded (ds) DNA (which encodes for the in vitro transcription (IVT) of single-stranded (ss) mRNA therapeutics) and dsRNAs (related to IVT production impurities) biopolymers. In this context, slalom chromatography (SC), a retention mode co-discovered in 1988, is being revitalized using the most advanced column technologies for improved determination of the critical quality attributes (CQAs) of such new therapeutics.

Objective: Bladder tissue models have been developed using smooth muscle cells (SMCs) on various scaffolds to mimic bladder morphology and physiology. This study investigates the effects of co-culturing fetal and adult SMCs on growth properties and protein profiles to understand cellular interactions and population kinetics.
Methods: Bladder tissue samples from 10 adult and 10 fetal New Zealand rabbits were divided into 5 groups: adult SMCs (A), fetal SMCs (F), 50%A+50%F (A+F), 75%A+25%F (3A+F), and 25%A+75%F (A+3F).
Riboflavin-ultraviolet-A collagen crosslinking treatments in improving dentin bonding and resistance to enzymatic digestion.

School of Dentistry and Institute of Oral Medicine, National Cheng Kung University, Tainan, Taiwan.
Background/purpose: The efficacy of riboflavin-ultraviolet-A (RF-UVA) treatment in crosslinking collagen and improving dentin bonding has been proven. However, biodegradation of the hybrid layer may compromise the bonding. The purpose of this study was to evaluate different RF-UVA treatments regarding their ability to preserve dentin bonding from enzymatic digestion.

Department of Biology, School of Sciences and Humanities, Nazarbayev University, Astana, Kazakhstan.
Background: Chitosan nanoparticles (CsNPs) are an effective and inexpensive approach for DNA delivery into live cells. However, most CsNP synthesis protocols are not optimized to allow long-term storage of CsNPs without loss of function. Here, we describe a protocol for CsNP synthesis, lyophilization, and sonication, to store CsNPs and maintain transfection efficiency.

The objective of this study was to investigate the water-holding capacity (WHC) and quality changes of beef during heating at specific temperatures (including 40 °C, 60 °C, 80 °C, and 100 °C), as well as the degradation of proteins and the distribution of water within the muscle at different heating temperatures. The experiment utilized the sirloin section from eight crossbred cattle of and breeds, with four sampling sessions, two cattle per session. Each cattle were divided into 30 beef sirloin samples, each weighing 150 ± 10 g, and each session was completed within 3 days with the following tests.
