Pan t cells isolation kit

Manufactured by Miltenyi Biotec
Sourced in United States

The Pan T-cell Isolation Kit is a laboratory product designed to isolate and enrich T-cells from various sample types. It utilizes a magnetic bead-based separation method to selectively deplete non-T-cells, resulting in a highly purified T-cell population.

Leukocyte Cytokine-Induced MMP-9 Secretion

Check if the same lab product or an alternative is used in the 5 most similar protocols
Peripheral Blood Mononuclear Cells (PBMCs) and PMN from healthy donors were obtained by density-gradient centrifugation from EDTA-treated whole blood using a density gradient medium (Granulosep, Eurobio-Abcys). Monocytes were purified from PBMCs by positive selection using CD14 immunomagnetic beads (MACS; Miltenyi Biotech) according to manufacturer instructions. Flow-through was then used to isolate T-lymphocyte by negative selection using the Pan T-cells isolation kit from Miltenyi (MACS).
Isolated leukocytes from healthy donors were then cultured in FBS-free medium and stimulated overnight (lymphocytes and monocytes) or for 1 hour (PMN) by IL-17 (200 pg/mL), IL-23 (100 pg/mL), or both cytokines. Culture media were harvested and analyzed for MMP-9 secretion by gel zymography.

Allogeneic Bone Marrow Transplant in Irradiated Mice

Check if the same lab product or an alternative is used in the 5 most similar protocols
Recipient B6D2F1 female mice received a 10-Gy irradiation followed by retro-orbital infusion of 5 × 106 bone marrow cells (C57BL/6J) + 1 × 106 CD3+ T cells from WT littermate or Suv39h1-KO male mice + 2 × 104 mastocytoma cells P815-GFP derived from DBA/2 (H-2d) mice (gift from Dr. B. Salomon). Total splenocytes and lymph nodes suspension cells were prepared for CD3+ T cells enrichment using pan T cells isolation kit (Miltenyi). Bone marrow suspension were prepared using leg bones. Control groups were constituted of irradiated mice receiving only bone marrow or bone marrow and P815-GFP cells. GVHD and Leukemia was evaluated two times per week. GVHD was evaluated as previously described48 (link),49 (link), and leukemia by flow cytometry (GFP+ H-2Kd +cells) and tumor bearing eyes.

T cells were purified from LN with Pan T cells Isolation Kit (Miltenyi Biotec). LN T cells were stimulated with or without plate-bound anti-TCRβ (1 μg/ml) and anti-CD28 (1 μg/ml) antibodies for 24 hours at 37 °C. Cultured cells were stained and analyzed by flow cytometry for CD40L and CD69 expression.

Isolation of T cells from Mice

Check if the same lab product or an alternative is used in the 5 most similar protocols
For T cells isolation, mice were sacrificed at the designated days of experiments to remove spleen and lymph nodes. The splenocytes were obtained by macerating spleens with a plunger and passing the tissue homogenates through a 70μm cell strainer. Cells were washed 2-3 times by centrifugation at 500g at 4°C for 5 min with incomplete RPMI-1640 to obtain a single-cell suspension. Pan-T cells were isolated using Pan-T cells isolation kit (Miltenyi Biotec, USA) using magnetic columns as per the manufacturer’s instructions. As and when required, the CD4+ and CD8+ T cells were isolated by positive selection using appropriate isolation kits (Miltenyi Biotec, USA). For isolation of lymph nodes (LN) lymphocytes, the brachial, axillary, and inguinal nodes were harvested and pooled together and the cells were isolated by mechanical maceration as described above.

Isolation and Activation of Tumor-Reactive T Cells

Check if the same lab product or an alternative is used in the 5 most similar protocols
A Pan-T cells Isolation kit (Miltenyi Biotec) and a CD8 T cell Isolation kit (Miltenyi Biotec) were used to isolate T cells from mouse spleen. T cells were primed by different groups of p13nsEV treatment for 5 days. After priming, the p13nsEV was washed away, and T cells were cocultured with tumor cells at 10:1 (tumor cell:T cell) for 2 days before being tested for interferon-γ (IFN-γ) expression by FC. For the T cell cytotoxicity assay, the p13nsEV-treated T cells were then cocultured with GFP-labeled cancer cells, which is the same source of tumor lysate to generate the p13nsEV. After 5 days of coculture, the death of cancer cells was examined by staining cells using the Zombie Aqua Fixable Viability Kit (BioLegend) followed by FC.

Transfer of Splenic T Cells in Mice

Check if the same lab product or an alternative is used in the 5 most similar protocols
Splenic T cells from C57BL/6 (CD45.1), WT (CD45.2) and Ahrr−/− (CD45.2) mice were isolated using Pan T Cells Isolation Kit (Miltenyi Biotech) according to manufacturer’s instruction. Both CD45.1 and CD45.2 cells were mixed together in 1:1 ratio. Rag1−/− mice were injected with 106 cells intravenously. Frequencies of CD45.1 vs CD45.2 in different subsets of IEL were analyzed after 8 weeks in the small intestine of recipient mice.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
