K562 Cell Post-thaw Viability Frozen in SeraFree™ Media versus Serum Containing Media

Viability of post-thaw cultures of K562 cells. Cells frozen in AMRESCO SeraFree™ Cryoprotection Media exhibited higher recovery than cells frozen in traditional RPMI freezing media containing DMSO and serum. Viability of cells recovering from cryopreservation in AMRESCO SeraFree™ Cryoprotection Media was comparable or better than that of cells in Competitors 1 and 2 serum-free freezing media. Viability was determined by standard trypan-blue exclusion assay.

HeLa Cell Viability after Storage in SeraFree™ Media vs. Serum Containing Media

Performance of AMRESCO SeraFree™ Cryopreservation Media rival serum-containing media. HeLa cells (1x106) were frozen in AMRESCO’s DMEM or RPMI SeraFree™ media, serum-containing freezing media and a competitor’s serum-free freezing media. Thawed cells were counted using standard trypan blue exclusion assay.
