Our cell pellets consisting of peripheral blood mononuclear cells (PBMCs) are collected at FDA-licensed donor centers and further processed using Ficoll gradient and several washes to remove platelets. The PBMCs are centrifuged into a tightly packed pellet, all media is removed and the cells are snap-frozen in liquid nitrogen. Cell pellets are suitable for DNA, RNA or Protein isolation, and we offer specialty pellets that are HLA typed upon request. All donors are tested for HIV, Hepatitis B and C, WNV, CMV and other blood-borne pathogens.
All cell pellets are obtained from properly consented donors. We conform to HIPAA standards to protect the privacy of the donor’s personal health information.
Human Material Precaution
It is best to use caution when handling any human cells. We recommend all human cells should be handled as if potentially infectious following biosafety level 2 procedures. Even with infectious virus assays or viral antigen assays, a negative test result may leave open the possible existence of latent viruses.
