OGSTONS LINE Meaning and
Definition
-
Ogstons line, also known as the Ogston's line or the Ogston phenomenon, refers to a principle observed in the field of electrophoresis, specifically in gel electrophoresis. It is a demarcation line formed in the gel matrix due to convection forces during the migration of large macromolecules.
Electrophoresis is a technique used to separate and study macromolecules, such as DNA, RNA, and proteins, based on their size and charge. The process involves the application of an electric field that causes the migration of the macromolecules through a gel matrix. However, a phenomenon called Ogstons line occurs due to the differential movement and entanglement of large macromolecules.
The Ogstons line is formed as a result of the convective motion created by the dragging or entangling of large macromolecules in a gel matrix. This line represents the boundary between the region of free-flowing, bulk-like migration of smaller molecules and the region of slow, convective motion of larger macromolecules. Macromolecules above a certain size will experience increased resistance to migration due to their entangled structure, leading to slower movement relative to smaller molecules.
The observation and understanding of Ogstons line are crucial in gel electrophoresis experiments as it allows researchers to discern the molecular weight or size of different macromolecules. By analyzing the migration patterns of various molecules, scientists can estimate their size or determine their differences in molecular structure. This information is valuable in various scientific fields, such as genetics, biochemistry, and molecular biology, to study the characteristics and functions of biological macromolecules.

Etymology of OGSTONS LINE
The term "Ogstons line" is named after its creator, Sir David Hamilton Ogston. He was a Scottish surgeon and medical researcher who made significant contributions to the field of ophthalmology (the study of the eye).
Ogston was born in 1847 and lived in Aberdeen, Scotland. He conducted various studies and research related to eye diseases, particularly focusing on glaucoma, which is a group of eye conditions that damage the optic nerve.
During his research, Ogston observed a distinct line within the cornea (the transparent front part of the eye) that marked the transition between the normal cornea and the area affected by glaucoma. This line is now known as "Ogstons line" in his honor.
Ogston's findings and the line he discovered helped in the diagnosis and understanding of glaucoma and its impact on the eye.
