One-click unlocking of the MO-DC efficient induction protocol

In tumor immunology, vaccine development, and autoimmune disease research, the importance of dendritic cells (DCs) as "immune commanders" is undeniable. However, traditional DC cell induction and differentiation experiments often face challenges such as cumbersome reagent ratios, significant batch variations, and unstable differentiation efficiency, causing countless researchers to spend precious time without achieving ideal results.

UA BIOSCIENCE's newly launched Human MO-DC Monocyte Induction Differentiation Cytokine Kit is a time-saving, labor-saving, and worry-free "one-stop" solution. It perfectly integrates the core factors required for DC induction, helping you effortlessly obtain mature dendritic cells.

Human MO-DC Monocyte Induction Differentiation Dendritic Cell Cytokine Kit (Catalog No.: UA090052) Protocol:

Preparation of Human Peripheral Blood Monocyte-Derived Dendritic Cells:

1. CD14⁺ Monocyte Isolation

1.1 Thaw frozen PBMCs and centrifuge at 300g for 5 minutes at room temperature. Discard the supernatant and resuspend the cells in complete RPMI 1640 medium (containing 10% FBS and 1% antibiotics). Perform cell counting and viability assessment (viability should be >95%). Label and isolate CD14⁺ cells using CD14 Nanobeads (human, Catalog No. S0K0004). Check the purity of CD14⁺ cells by flow cytometry; for optimal results, purity should exceed 95%.

2. Induction of Monocytes into Immature Dendritic Cells

2.1 Adjust the concentration of isolated CD14⁺ cells to 1-2×10⁶ cells/mL using complete RPMI 1640 medium (with 10% FBS and 1% antibiotics). Seed 1 mL per well in a 24-well plate and immediately add recombinant human cytokines IL-4 (50 ng/mL) and GM-CSF (100 ng/mL). Place the plate in a 37°C, 5% CO₂ incubator to initiate culture.

2.2 After 48 hours, observe cell status under a microscope. If cells adhere well: gently aspirate half of the old medium and slowly add an equal volume of fresh complete medium with the same concentrations of IL-4 and GM-CSF. If cells adhere poorly or float: do not discard old medium; directly supplement with fresh complete medium containing the same cytokine concentrations.

Continue culture: After medium change/supplementation, continue culturing for 72 hours to obtain immature dendritic cells.

3. Induction of Immature Dendritic Cells into Mature Dendritic Cells

3.1 Gently collect immature dendritic cells from Step 2 and centrifuge at 300g for 10 minutes. Discard the supernatant and resuspend cells in fresh complete medium at a density of 5×10⁵ cells/mL. Seed cells into a new 24-well plate and add maturation induction factors: TNF-α (10 ng/mL), IL-1β (10 ng/mL), IL-6 (50 ng/mL), and PGE2 (1 μg/mL). Incubate at 37°C, 5% CO₂ for 48 hours to obtain mature dendritic cells for downstream experiments.

Flow Cytometry Analysis

1. Cell Collection: Harvest cells after cytokine treatment.

2. Cell Counting: Count cells and calculate total number. Centrifuge at 300g for 5 minutes, discard supernatant, and resuspend in cell staining buffer (10% FBS or 1% BSA in PBS) at 5-10×10⁶ cells/mL.

3. Fc Receptor Blocking: Incubate cells on ice with 100 μL suspension (containing 5-10×10⁵ cells) and 1 μL Human FcR Blocking Reagent (Catalog: S0F0012) for 30 minutes. Centrifuge at 300g for 5 minutes and discard supernatant.

4. Antibody Staining: Resuspend cells in 100 μL PBS with 10% FBS (or 1% BSA). Add the following antibodies:

APC Rabbit Anti-Human CD80 Antibody (Starter)

APC Rabbit Anti-Human CD86 Antibody (Starter CAT: S0B1658)

Anti-Hu CD83 APC

Brilliant Violet 711™ anti-human CD11c Antibody

Brilliant Violet 421™ anti-human CD14 Antibody

Alexa Fluor® 488 anti-human HLA-DR Antibody

Incubate at 4°C for 30 minutes, centrifuge at 300g for 5 minutes, and discard supernatant.

5. Cell Washing: Wash cells with PBS to remove residual antibodies and resuspend in PBS.

6. Viability Staining: Add 7-AAD to each well and incubate at room temperature for 5 minutes in the dark.

7. Flow Cytometry Analysis.
