HUVECs cultured in EGM-Plus Growth Media offer faster proliferation rates while maintaining the same high quality characterization as HUVECs in EGM Media Lonza s Cryopreserved HUVECs are shipped as frozen primaries They are guaranteed to express CD31/105 and survive in culture through 15 population doublings ( except HUVEC-XL guaranteed through 5 PD) All cells test negative for mycoplasma bacteria yeast and fungi HIV-1 hepatitis B and hepatitis C are not detected for all donors and/or cell lots A Certificate of Analysis is provided for each cell lot purchased Our pooled vs single donor options allow researchers to study or exclude donor variability from their experiments Depending upon the study pooled version is typically utilized to reduce donor variability while single donor option allows researchers to assess donor-specific differences HUVEC-XL size consists of 10 million cells/amp achieved by pooling donors
