SDS-PAGE analysis of zebra finch eggshell matrix. Gel electrophoretic analysis of 75 μg of eggshell matrix applied in 25 μl sample buffer. The relative mobility of molecular weight markers is indicated in kDa. The arrow points to a prominent 17 kDa band that was examined by N-terminal and internal amino acid sequencing. The resulting sequences and their alignment to similar eggshell proteins are shown at right. Identical amino acids are highlighted
