Selection antibiotics
18 listings from 9 suppliers · 2 Japanese makers
Japanese name: 選択用抗生物質（カナマイシン・アンピシリン等）
Selection antibiotics such as kanamycin and ampicillin let only plasmid-bearing transformants grow in the medium, for molecular biology work and seed culture. Buyers first match the antibiotic to the resistance gene on the plasmid (AmpR, KanR, CmR), then compare powder against ready-to-use solution, purity grade and pack size. Carbenicillin, which breaks down more slowly than ampicillin, helps avoid satellite colonies in long cultures. Use the list below to see which makers offer which products and who sells them in Japan.
