Pe conjugated anti mouse ifn γ

Manufactured by Thermo Fisher Scientific
Sourced in United States

PE-conjugated anti-mouse IFN-γ is a laboratory reagent used to detect and quantify mouse interferon-gamma (IFN-γ) in samples. It consists of a phycoerythrin (PE) fluorescent dye conjugated to an antibody that specifically binds to mouse IFN-γ.

Murine TNF-α, IFN-γ, G-CSF and IL-6 were purchased from PeproTech (Rocky Hill, NJ). Murine IL-2 was purchased from Millipore (Billerica, MA). PE-conjugated anti-mouse IFN-γ, PE-conjugated anti-mouse MULT-1 were purchased from eBioscience (San Diego, CA). PE-conjugated anti-mouse H60 and PE-conjugated anti-panRAE-1 were purchased from R&D Systems. Anti-asialo-GM1 mAb was purchased from Biolegend. Anti-Ly6G mAb was purchased from BioExpress (clone 1A8).
Plasmids pG, pI6, pCXCL1, and pIFN-γ are expression vectors carrying the cDNA encoding murine G-CSF, IL-6, CXCL1, and IFN-γ, respectively. Plasmid psTNF-α is the expression vector carrying the cDNA encoding IFN-β signal peptide and extracellular domain of TNF-α. These plasmids were constructed by the insertion of cDNA into plasmid pcDNA3.1 (Invitrogen, Carlsbad, CA) in our laboratory. All of the vectors were identified by in vivo expression (Ref 7 and Supplemental Figure S12).

To determine the number of regulatory T cells in the splenocytes, flow cytometry was performed, as previously described [7 (link)]. The splenocytes were washed with PBS and stained with fluorescein isothiocyanate (FITC)-conjugated anti-mouse CD4 (eBioscience, San Diego, CA, USA) and phycoerythrin (PE)-conjugated anti-mouse CD25 (eBioscience, San Diego, CA, USA). Next, the cells were fixed and stained with Alexa Fluor 647 anti-mouse Foxp3 (BD Biosciences, San Jose, CA, USA) overnight at 4 °C in the dark. After washing, the cells were analyzed. In order to measure Th1 and Th17 cells in the splenocytes, FITC-conjugated anti-mouse CD4 (eBioscience, San Diego, CA, USA), PE-conjugated anti-mouse IFN-γ (eBioscience, San Diego, CA, USA), and PerCP/Cyanine5.5-conjugated anti-mouse IL-17A (eBioscience, San Diego, CA, USA) were stained according to the supplier’s instructions.

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.
