Kohjin Bio KBM581 1L (Serum-free Media for T-cell expansion) is a RUO product.

Product description

  • KBM 500 series are the most frequently used for adoptive immunotherapy in Japan.
  • All KBM media are prepared using selected high-quality reagents or raw materials including GMP-grade stuff.
  • They do not contain proteins other than serum albumin which is injection-grade and recombinant human insulin.
  • The shelf life of each medium is comparatively longer even in the presence of L-glutamine.
  • Buffering ability is strengthened so that pH during culture is stable.
  • Kanamycin sulphate is formulated as an antibiotic.
  • The products are manufactured at our factory as certified ISO 9001 and ISO 13485
