Serum-Free Cell Culture Media, Wholesale

Serum-free media replace the variable contribution of serum with defined nutrients, salts, lipids, trace elements and growth-supporting components. The category includes CHO media for recombinant protein work, HEK293 media for transient and stable expression, hybridoma media, insect cell media and reduced-serum media, together with the feed supplements used in fed-batch processes.

For a reseller this is the higher-value end of the range. It serves the monoclonal antibody, vaccine production and bioprocessing segments, where customers reorder repeatedly once a medium is qualified.

• CHO serum-free media: base formulations for suspension CHO lines, with and without phenol red, glutamine or HT supplement.
• Chemically defined and animal-component-free CHO media: for customers with raw-material restrictions and supplier-qualification files.
• CHO feeds: concentrated feed supplements for fed-batch and intensified processes.
• HEK293 serum-free media: for transient expression and viral vector work.
• Hybridoma and insect cell serum-free media: for antibody-producing and insect cell platforms.
• Reduced-serum media: DMEM, DMEM/F-12 and MEM based formats, including a transfection medium.
• Powder media: many CHO media and feeds are listed as dry powder in larger pack sizes for reconstitution at the customer's site.

Pack sizes are shown per product in the product list.

Production customers qualify a medium once and then purchase the same formulation for the life of the process, so continuity of supply and lot reservation matter more here than in any other category. Powder formats are the practical way to hold larger volumes: they ship lighter and most carry a 24-month listed shelf life against 12 months for most liquid bottles. Liquid bottles suit evaluation and smaller process-development customers.

When you inquire, say which formulations your customers have qualified, the quantity per quarter in liquid and in powder, and whether you need a lot held. The quotation will set out case configuration, lot reservation and lead time for first and repeat shipments.

• Inquiry: send the product list, pack sizes and the quantity per quarter, or submit an inquiry list from the product pages.
• Quotation: written, by email, with unit prices at the quoted volume, case configuration and lead time for that order.
• Minimum order quantities: confirmed on request per product and destination.
• Bulk powder: where a product page lists a powder format, larger dry quantities can be quoted.
• Private label: your label and documents, agreed in writing before production.
• Lot reservation: the same lot held for your customers across a season, requested at quotation.
• Lead time: quoted per order.
• Temperature control: shipments that need cold-chain handling are quoted case by case, including packaging and route.
• Documents: on request, confirmed per product.
