SDS-PAGE Gel Electrophoresis of Milk Proteins - Caseins and Whey Components #3886986 (License: Personal Use)

This Coomassie-stained SDS-PAGE gel resolves eight sample lanes containing purified milk proteins, including casein fractions (αs-, β-, κ-CN) and whey proteins (β-Lg, α-La). Molecular weight markers range from 14.4 kDa to 141 kDa, enabling precise estimation of protein sizes; prominent bands align with expected masses-e.g., β-casein (~24 kDa), β-lactoglobulin (~18 kDa), and α-lactalbumin (~14.2 kDa).

Used in biochemistry and food science education/research to demonstrate protein purification, composition analysis, or quality control of dairy products; supports user intent for academic illustration, lab protocol documentation, or scientific publication figure.
