Assessing Immune Cell Activation in Tumor Samples

Check if the same lab product or an alternative is used in the 5 most similar protocols
Mononuclear cells isolated from fresh tumor specimens were stimulated with 50 ng/mL phorbol 12-myristate 13-acetate (PMA) + 1 μg/ml ionomycin in the presence of anti-CD107a FITC monoclonal antibody (BioLegend) for 1 h followed by 3 h incubation with brefeldin A (BioLegend). Unstimulated cells were used as control. Cells were then washed in PBS, stained with anti-CD45 PerCP (EXBIO), anti-CD3 Alexa Fluor 700 (EXBIO) or APC-eFluor780 (eBioscience), anti-CD4 ECD (Beckman Coulter), anti-CD8 HV500 (BD Biosciences) and anti-CD56 Alexa Fluor 700 (BioLegend) monoclonal antibodies, fixed in fixation/permeabilization buffer (eBioscience), permeabilized with permeabilization buffer (eBioscience) and stained with anti-IFN-γ PE-Cy7 (eBioscience), anti-granzyme B Brilliant Violet 421 (BD Biosciences) and anti-perforin APC (BioLegend) monoclonal antibodies. The percentage of CD3+CD8+ T cells and CD3CD56+ NK cells producing IFN-γ and degranulating upon PMA/ionomycin stimulation were determined by flow cytometry. The data were analyzed with the FlowJo software package (Tree Star, Inc.).

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.
