Overview

Agarose gel electrophoresis is a laboratory technique that separates nucleic acid fragments, such as DNA and RNA, according to their size by driving them through a porous agarose gel under an applied electric field, with smaller fragments migrating faster than larger ones. Because nucleic acids carry a uniform negative charge, they move toward the positive electrode, and the gel matrix, formed from agarose derived from seaweed, acts as a molecular sieve that resolves fragments into distinct bands that can be visualised with stains. It is a routine and versatile method in molecular biology used to check the quality and size of nucleic acids, confirm amplification products, and support cloning, genotyping, and diagnostics. Within this field the journal publishes peer-reviewed research that applies molecular and genomic techniques to a range of questions, including proteomic and genomic methods for cancer diagnostics and personalised medicine, the detection of genetically modified crops, and the characterisation of antimicrobial-resistance and bacterial-identification markers such as rpoB mutations and staphylococcal strains. Further studies examine gene polymorphisms in anaemia of chronic kidney disease, molecular approaches for identifying freshwater fish species, sequence analysis of heat-shock-protein and viral genes, single-nucleotide-polymorphism profiling for personalised immunosuppression, and mutation analysis in metabolic disease, reflecting the central role of gel-based nucleic-acid separation in molecular research.
