Miltenyi, 170-076-138, MACS® GMP PepTivator® BKV VP1

Background information
BKV is a ubiquitous polyomavirus. After primary infection BKV persists in a latent state. Virus reactivation might occur in immunodeficiency or during immunosuppression. VP1 is the major capsid protein of BKV, expressed late in the lytic cycle.

Applications
Adoptive transfer of BKV VP1-specific T cells may be an effective tool for the treatment of BKV-associated infections after stem cell transplantation or solid organ transplantation.1,2
In vitro stimulation of BKV VP1-specific CD4+ and CD8+ T cells with MACS GMP PepTivator BKV VP1 causes the production of the effector cytokine IFN-γ. The secretion of IFN-γ then permits the enrichment of BKV VP1-specific effector/memory T cells using the CliniMACS® Cytokine Capture System (IFN-gamma).3
