Human PB CD14+ Monocytes (Age: 24), Negative selected, 5 x 10^7 cells (MTS-1022-JF11)

Overview

Description
Monocytes are immune cells that form an important bridge between the innate and adaptive immune response. These cells exist in various phenotypes based on cell surface marker expression and participate in the pathobiology of many systemic diseases. CD14 is known as monocyte differentiation antigen on the surface of myeloid lineage. This protein has a major role in immune recognition and reactivation. CD14+ monocytes are perhaps the most readily available precursors used to generate macrophages and dendritic cells, provide an ideal model for the study of macrophage biology and mechanisms.
These human CD14+ monocytes are purified from peripheral blood by removing other cell types using immunomagnetic negative selection, with the highest viability and plating efficiency. Peripheral blood is collected from donors who have screend for Hepatitis B, Hepatitis C, HIV-1, HIV-2, WNV, and CMV.
Isolated cells are characterized flow cytometry to ensure the enrichment of CD14+ cells.
5 x 10^7 cells per vial.
Cells are negative for bacteria, yeast, fungi, and mycoplasma.
Repeated freezing and thawing of cells is not recommended.

How does negative selection influence downstream macrophage differentiation and polarization?

Many teams find negative-selected monocytes differentiate efficiently, but the key is to standardize recovery, density, and cytokine schedule. If your downstream assays are activation-sensitive, negative selection can offer a practical advantage by reducing the chance that isolation affects early signaling baselines. We recommend running a short baseline check (viability + minimal phenotype confirmation) and then proceeding with a locked differentiation protocol. If you want, we can provide guidance on minimizing variability during the first 24 hours, which is often when differences appear.

We plan to run monocyte-to-macrophage assays for drug screening-how do we ensure consistent assay performance?

Use defined differentiation media, lock down seeding density, and include reference controls across plates. For screening, avoid changing multiple variables at once; standardize recovery and stimulation windows. We can help you design a simple performance dashboard-key readouts that indicate whether differentiation and activation are on track-so you can detect drift early. Optional add-on validation services are also available if you'd like an external benchmark for baseline performance.

Can you support custom requests such as matched age ranges or repeated supply planning?

Yes. If your project requires repeated runs or donor-context alignment, we can discuss supply planning, documentation needs, and deliverable formats upfront. Many clients benefit from a defined sourcing and release plan that reduces operational uncertainty. Our aim is to help you maintain continuity across the full program, not just a single experiment.

  • These negative-selected CD14 monocytes were a great match for our functional assays
    We monitored spontaneous cytokine release and saw low background, which gave us better separation between treatment groups. Differentiation into macrophages was uniform, and the cells remained healthy across multi-day culture. The handling instructions were clear and realistic-especially for washing steps to minimize loss. Our flow panel showed a clean monocyte population with expected marker expression, and we were able to generate consistent data across replicates.
  • This age-24 negative-selected prep is a dependable foundation
    We used this vial in a biomaterials study where surface receptor integrity matters. Negative selection helped us avoid any concerns about epitope masking or receptor engagement, and the cells performed well across adhesion and polarization experiments. Recovery was good, and the cultures remained stable with minimal debris. In our macrophage differentiation, morphology and marker progression were consistent, and we observed robust stimulus-dependent changes in gene expression.
  • This vial offered a good balance of scale and quality
    The cells thawed cleanly and were easy to count, with minimal aggregates. Negative selection appeared to preserve functional behavior; we obtained clear, dose-dependent responses in TLR assays and clean baseline controls. Macrophage differentiation was consistent, and the derived macrophages showed strong phagocytosis in our bead uptake tests. The delivery was prompt and well packed, and support was helpful when we asked about recommended recovery timing.
