Santa Cruz Biotechnology offers an expansive library of transfected lysates that overexpress structural proteins. Structural proteins are essential for maintaining the overall structural integrity of cells. Proteins which maintain structural integrity also ensure proper locomotion of the cell, which is essential for pinocytosis, phagocytosis and cytokinesis. Cell structure influences cell surface adhesion and migration, both of which are important factors in cancer metastasis. In addition to cytoskeletal organization, structural proteins play a critical role in cell differentiation and tissue specialization. Structural proteins also play various roles in stabilizing actin filaments, thereby contributing to actin polymerization and reorganization. Transfected lysates that express structural proteins offer a reliable means to evaluate antibody quality and serve as excellent positive controls for experiments involving antibodies.
