Microarray Techniques

Microarray Techniques is a core topic in advanced biotechnology for Zambian university students studying biomedical sciences. It covers laboratory methods used to analyze gene expression, genotyping, and molecular interactions through DNA, oligonucleotide, and cDNA microarrays. The principle of hybridization between probes and targets is examined, along with key steps such as probe preparation, sample handling, hybridization, and fluorescence scanning. Applications include disease diagnosis, pharmacogenomics, and biotechnology, offering high-throughput, cost-effective analysis. Understanding this well-established technology prepares Zambian diploma and degree students for molecular diagnostics, research roles, and advanced laboratory practice. Mastery of microarrays is essential for interpreting genomic data, supporting clinical decisions, and contributing to Zambia’s growing biotechnology sector.
