This technique is that packed a tube tipped with ground up silica gel, then wetting the gel with water and pipetting in an amino acid solution at the top. Chloroform then inserted to wash the amino acid solution through and added a methyl red dye. The dye formed red bands against to an orange background which helped show up the separated amino acids. First tine Sanger tested
