Autoradiography in Molecular Biology | Principle, Components & Uses
Autoradiography is a powerful technique used to detect and visualize radioactive molecules in biological samples. In this video, we explain the principle, components, and complete process of autoradiography used in molecular biology and biochemistry.

You will learn how radioactive isotopes such as Phosphorus-32 (³²P), Tritium (³H), and Carbon-14 (¹⁴C) are used to label biological molecules and how emitted radiation exposes photographic film to produce an autoradiograph.

The video also explains the components involved in autoradiography, including radioactive samples, gels or membranes, photographic film, light-tight cassette, and film development systems.

This technique is widely used in molecular biology experiments such as DNA sequencing, Southern blotting, and gene expression analysis.

Topics Covered:

Principle of autoradiography

Components used in autoradiography

Step-by-step autoradiography process

Measurement of radiation using autoradiography

Radioactive isotopes used in labeling

Applications in molecular biology and genetics

This video is helpful for students preparing for MSc Biotechnology, Life Sciences, Biochemistry, CSIR-NET, GATE, and other competitive exams.
