BioLife solutions and Charles River have partnered to provide CGMP-compliant biopreservation media products. This media significantly extends stability and improves post-preservation viability and function of biologic source material, intermediates, and final products.

Antigen products are proteins and viral lysates that stimulate in vitro immune responses. Various antigens are offered that stimulate immune cells, all of which are tested for bioactivity using PBMCs.

Antigens and peptides: Antigen sequences can be used to evaluate a donors immune response. Peptides are also provided for use with antigen specific T cells and antigen-presenting cells. All antigens are tested for bioactivity using Charles River PBMCs. These antigens are available in 100 μg/vial or 1 mg/vial sizes, depending on the specific antigen.
