Ly 6g

Manufactured by Merck Group

Ly-6G is a cell surface marker that is primarily expressed on the surface of neutrophils, a type of white blood cell. It is commonly used in flow cytometry and other immunological assays to identify and quantify neutrophil populations in biological samples.

BAL fluid was collected from each animal through cannulation of the exposed trachea, and flushing twice with .7mL of PBS. BALF samples were centrifuged at 500xG for 5 minutes, and supernatant was immediately frozen for later cytokine analyses. For flow cytometry, pelleted cells were resuspended in FACS (PBS + 5% FBS) buffer for staining and with Zombie NIR (Biolegend, 423105, SanDiego, CA), CD45, Alexa Fluor 532 (eBioscience, 58-0459-42,San Diego, CA), CD11c, PE-Cy7 (Biolegend, 117317, SanDiego, CA), CD11B, BV480 (BD Biosciences, 566117, SanJose, CA), SIGLEC F, AF700 (eBioscience, 56-1702-80, SanDiego, CA), Ly-6c, FITC (Biolegend, 128005, San Diego, CA),and Ly-6G, BV650 (Biolegend, 127641, San Diego, CA) and then fixed in IC-fixation buffer (eBioscience, 00-8222-49, San Diego, CA). Samples were run on a Cytek Aurora Borealis at the University of Virginia flowcytometry core. Neutrophils are Zombie NIR−, CD45+,CD11C−, CD11B+, and Ly-6G+; eosinophils are Zombie NIR−,CD45+, CD11C−, CD11B+, and Siglec-F+; inflammatory monocytes are Zombie NIR−, CD45+, CD11C−, CD11B+, Ly-6G−, and Ly-6C+.
Cytokine analyses were performed via Luminex Mouse 32-plex (MCYTMAG-70K-PX32, Millipore-sigma). Samples were run following manufacturers protocol after an 18-hour incubation before being run on Luminex® analyzer (MAGPIX®).

Analyzing Immune Cell Subsets in BALF

Check if the same lab product or an alternative is used in the 5 most similar protocols
BAL fluid was collected from each animal through cannulation of the exposed trachea and flushed twice with 0.7mL of PBS. BALF samples were centrifuged at x500 g for 5 minutes, and supernatant was immediately frozen for later cytokine analyses. For flow cytometry, pelleted cells were resuspended in FACS (PBS + 5% FBS) buffer for staining and with Zombie NIR (BioLegend, 423105), CD45, Alexa Fluor 532 (eBioscience, 58-0459-42), CD11c, PE-Cy7 (BioLegend, 117317), CD11B, BV480 (BD Biosciences, 566117), SIGLEC F, AF700 (eBioscience, 56-1702-80), Ly-6c, FITC (BioLegend, 128005), and Ly-6G, BV650 (BioLegend, 127641) and then fixed in IC-fixation buffer (eBioscience, 00-8222-49).

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.
