Foxp3 clone 259d c7

Manufactured by BD

FoxP3 (clone 259D/C7) is a monoclonal antibody used for the detection and analysis of FoxP3-expressing cells, a transcription factor that is essential for the development and function of regulatory T cells. This antibody can be used in various immunological techniques, such as flow cytometry, immunohistochemistry, and western blotting, to identify and quantify FoxP3-positive cells.

IFN-γ and TNF-α secreting, and FoxP3+, CD4+ T-cells in infant PBMC were identified by ICS (intracellular cytokine staining). PBMC were washed with media, and then left unstimulated or stimulated for 4 h with PMA/Ionomycin (BD Biosciences). The stimulations were done in the presence of 1 μl Brefeldin A (BD Biosciences). Cells were first stained with surface Ab to CD45RO (clone UCHL1), fixed and permeabilized with the FoxP3 buffer set (BD Biosciences), and then stained with Abs to CD3 (clone UCHT1), CD4 (clone SK3), CD8 (clone SK1), IFN-γ (clone B27), TNF-α (clone 6401.1111), and FoxP3 (clone 259D/C7) (all Abs from BD Biosciences). Cells were analyzed using a FACSAria flow cytometer (BD Biosciences). LIVE/DEAD® Fixable Dead Cell Stain Kit (LDA) (Invitrogen) was used to exclude nonviable cells from analysis. Relevant cells were identified as LDA−/CD3+/CD4+/CD8−/CD45RO+ or CD45RO−/IFN-γ+ or TNF-α+ or FoxP3+ cells (Supplementary Fig. 1). Data was analyzed using FlowJo® software (Treestar).

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.
