hPBMC Donor Screening & QC Platform

Creative Bioarray proudly presents our state-of-the-art hPBMC Donor Screening & Quality Control (QC) Platform, a cornerstone of our commitment to excellence in immune system reconstruction for humanized mouse models. This innovative platform is meticulously designed to ensure the highest success rates for immune reconstruction and to extend the dosing window, crucial factors for the reliability and effectiveness of preclinical studies.

Our hPBMCs undergo a rigorous internal screening process, ensuring that each batch of PBMCs is pre-validated in vivo for optimal performance in your experiments. This stringent quality control not only guarantees a high success rate for immune system reconstruction but also secures an extended dosing window of up to three weeks, providing you with a robust and reliable research environment.

Why hPBMC Donor Screening & QC is Essential?

Human PBMCs are sourced from healthy donors, each exhibiting unique capabilities in terms of PBMC reconstruction, tumor cell antagonism, and response to immunotherapy drugs. The versatility of the PBMC model is a significant advantage, as it supports a wide range of tumor cell types, offering a diverse array of tumor-end targets to meet the efficacy testing requirements for various immunotherapies. However, the variability in antagonistic capabilities between different tumor cells and PBMCs poses a challenge: when PBMC donors are changed, historical data often lacks significant relevance to new donors. Consequently, most PBMC projects necessitate donor screening to identify donors compatible with the candidate tumor cells, with donor selection based on demonstrated efficacy.

Criteria of hPBMC Donor Screening

  • hCD45+ Cell Proportion: After 14 days post-inoculation, the proportion of hCD45+ cells in peripheral blood should be at least 10%.
  • Graft-versus-Host Disease (GvHD) Onset: The onset of GvHD must occur at 5 weeks or later, with no more than 10% weight loss.

Advantages

  • Stable hPBMC reconstitution and compatibility: Over 90% of human tumor cells can be selected for reconstruction from three donors.
  • Comprehensive pre-screening platforms: Offering both in vivo and in vitro pre-screening platforms to meet diverse customer needs.
  • Robust PBMC donor reserves: Large-scale PBMC donor backup ensures stable donor use throughout consecutive projects.
