We have a variety of antibiotics for carrying out cloning, cell biology, and gene expression studies. Choose between G418, Puromycin, or Hygromycin B for selection and maintenance of eukaryotic cells stably transfected with vectors expressing neomycin, puromycin, and hygromycin resistance cassettes, or Anhydrotetracycline to induce expression of tetracycline-controlled promoters.
