Answer:A 1000 mL bottle of ready-to-use liquid Cell Boost 7b supplement.
Answer:Cell Boost 7b is a concentrated alkaline amino-acid feed; Cell Boost 7a contains a broader nutrient mix including amino acids, vitamins, salts, trace elements and glucose.
Answer:Yes. The alkaline formulation can irritate skin and eyes; use suitable PPE and follow the product safety data sheet.
HyClone Cell Boost 7b is a chemically defined, animal-derived component-free liquid feed supplement developed for Chinese hamster ovary cell fed-batch culture. The 1000 mL bottle contains a ready-to-use concentrated amino-acid solution with alkaline pH; it is not a dry powder product. Cell Boost 7b is designed to complement Cell Boost 7a, which supplies a broader set of nutrients, including glucose, vitamins, trace elements and salts. Together the feeds support nutrient replenishment during recombinant-protein production, subject to the selected feeding strategy. The alkaline formulation requires suitable chemical handling and eye/skin protection. Determine addition rates from cell growth and nutrient measurements, rather than assuming the same volume or dosing interval applies to both feeds.
Unless otherwise stated, the minimum order amount is USD 1,000.
