Marmoset Splenocytes
Marmoset primary cells (Callithrix jacchus) isolated using validated methods. Available fresh or cryopreserved with viability guarantee. Contact us for cell-specific specifications.
Marmoset Splenocytes Overview
Marmoset Splenocytes are primary immune cells isolated from common marmoset (Callithrix jacchus) spleen tissue. The marmoset immune system is well-characterized and the species serves as a key model for infectious disease (EBV, measles, Zika), autoimmunity, and vaccine research.
Common Applications
- Vaccine immunogenicity and T cell response profiling
- ELISpot and cytokine release assays
- Infectious disease and viral pathogenesis studies
- Immune cell phenotyping by flow cytometry
Product Details
Splenocytes are prepared by mechanical dissociation and cryopreserved. Each lot ships with a Certificate of Analysis documenting viability, cell count, and donor information. Available in 10M, 25M, and 50M cell counts.
About the Marmoset
Callithrix jacchus
Common marmosets are small New World primates increasingly used in neuroscience and aging research.
Their small size, short lifespan, and twinning make them ideal for developmental studies, gene therapy research, and as transgenic models.

Splenocytes contain a mixed immune cell population including T cells (40-60%), B cells (30-50%), NK cells (5-10%), monocytes/macrophages, and dendritic cells. The exact composition varies by species and individual donor. Flow cytometry immunophenotyping data is available on request.
Splenocytes are isolated by gentle mechanical dissociation of the spleen through a cell strainer, followed by red blood cell lysis (ACK buffer). The resulting single-cell suspension is washed and resuspended in culture medium or cryopreservation medium.
Thaw rapidly at 37°C, dilute dropwise into pre-warmed RPMI + 10% FBS. Centrifuge at 300g for 10 minutes. Resuspend in fresh medium and rest overnight before functional assays for optimal recovery.
Post-thaw viability is typically ≥70%. Splenocyte function (proliferation, cytokine production) recovers well after overnight resting. Fresh splenocytes are shipped with ≥90% viability.
Yes. Donor demographics (age, sex, weight, health status) are available. Matched sets (splenocytes + PBMCs + serum from the same donor) can be arranged.
