Cell-Vive™ Low DMSO Cryopreservation, GMP preserves T cell viability during post-cryopreservation expansion, at similar or higher levels than other commonly used solutions containing 10% DMSO (denoted as Comp C in the figures). After a 9-day expansion protocol using anti-human CD28, anti-human CD3, and IL-2, activated and expanded T cells were cryopreserved and thawed. Viability (A) and cell recovery (B) (% of cells recovered versus the initial number frozen) were determined at thaw. Viability was assessed by Trypan blue; cell recovery was assessed using an automatized cell counter. Cells were re-activated with 1 µg/mL of Ultra-LEAF™ anti-human CD3 antibody (Cat. No. 317347), 1 µg/mL of Ultra-LEAF™ anti-human CD28 antibody (Cat. No. 302943), and viability was determined again at several time points post-thaw (C). Expansion ability was assessed after a 6-day (144 hours) culture period. The expansion fold was calculated by dividing the number of viable cells at day 6 by the number of viable cells at 2h post-thaw (D). Flow cytometry was used to quantify CD4+ and CD8+ T cell populations at thaw, after the above 9-day expansion protocol (E).

Description

Cell-Vive™ Low DMSO Cryopreservation, GMP is specifically formulated to support immune cell cryopreservation, while making use of low DMSO content. It is a chemically-defined formulation, prepared without bovine or other animal components. It is suitable for use in the cryopreservation of several T cell sources, without affecting relevant T cell properties. When used under the appropriate conditions, this product can preserve T cell viability and expansion capacity. This GMP product is suggested for use in research and for further manufacturing applications. The benefits of this cryopreservation solution include:

  • Low DMSO content.
  • Chemically-defined formulation.
  • Effective in cryopreserving T cells from multiple sources (PBMCs, CD3+, expanded T cells).
  • Able to maintain T cell properties after cryopreservation.
  • Minimizes safety risks associated with DMSO.
  • Improved lot-to-lot consistency.

Application Notes

For cryopreservation, a range between 5-50 million cells per 1 mL of Cell-Vive™ CD Low DMSO Cryopreservation, GMP is recommended. The appearance of the product in liquid form is clear with a slight yellow color. 

Cryopreservation protocol

  1. Prepare an immune cells suspension following an appropriate protocol.
  2. Centrifuge cells at 300 x g for 5 minutes to obtain a pellet. Carefully decant or aspirate supernatant
  3. Resuspend pelleted cells with Cell-Vive™ CD Low DMSO Cryopreservation, GMP and dispense the cell suspension into a cryovial.
  4. Immediately transfer the cryovial into a cell freezing container and store it at -70°C
  5. After 24-36 hours, transfer cryovials into a liquid nitrogen tank for long-term storage.

Thawing cells protocol

  1. Thaw cryovials containing cells by putting them in a 37°C water bath with very gently swirling. Thaw until only a small ice fragment is present.
  2. In a biosafety hood, add 1 mL of preferred cell culture media such as IMDM into the vial and then transfer content into a 15 mL conical tube containing 8mL of cell culture media at room temperature. Gently mix
  3. Centrifuge cells at 300 x g for 5 minutes. Carefully decant or aspirate supernatant
  4. Resuspend the cells at the desired density with cell culture media.
