Sodium dodecyl sulfate (SDS) also known as sodium lauryl sulfate is a versatile anionic surfactant with a broad range of applications in cell biology biochemistry and various industries Its amphiphilic nature characterized by a hydrophobic hydrocarbon tail and a hydrophilic sulfate head group makes it an effective detergent capable of solubilizing and denaturing proteins lipids and other hydrophobic molecules In protein biochemistry SDS plays a pivotal role in protein extraction and SDS-PAGE (sodium dodecyl sulfate-polyacrylamide gel electrophoresis) Its ability to denature proteins by disrupting their secondary and tertiary structures allows for their uniform migration through a polyacrylamide gel matrix based on their molecular weight This technique SDS-PAGE has become an indispensable tool for analyzing protein size and purity Beyond protein analysis SDS also finds applications in nucleic acid extraction and hybridization techniques Its detergent properties aid in the lysis of c
