Anti sca 1 percpcy5

Manufactured by BioLegend
Sourced in United States

Anti-Sca-1-PercpCy5.5 is a fluorescently-labeled antibody that binds to the Sca-1 (Stem Cell Antigen-1) protein. Sca-1 is a cell surface marker commonly used to identify and characterize stem and progenitor cells in various tissues. The PerCP-Cy5.5 fluorescent dye is conjugated to the antibody, allowing for detection and analysis of Sca-1-positive cells using flow cytometry.

For stem-cell quantitation, the cultured bone marrow nucleated cells were co-stained with a combination of PE-Cy7 labeled antibodies against mouse CD3, CD4, CD8, B220, Gr-1, Mac-1 and TER-119, anti-Sca-1-PercpCy5.5, anti-CD48-PE and anti-CD150-APC (all from Biolegend). DAPI was used for dead-cell discrimination. Due to the presence of cytokine stem cell factor (SCF), we could not detect the c-Kit marker of those cultured cells. So hereafter we did not use c-Kit in detecting subpopulation. Flow cytometry and flow sorting were conducted with a CyAn (DakoCytomation) or a FACSCalibur system (BD Biosciences). FlowJo software Version 7.6.2 (TreeStar) was used for data analysis.

The SV fraction suspended in PBS containing 2% fetal calf serum was incubated with a
mixture of antibodies containing either anti-CD31-PE-Cy (BioLegend, San Diego, CA,
U.S.A.), anti-CD34-PE (BioLegend), anti-Sca1-PerCP/Cy5.5 (BioLegend), and anti-PDGFRα
(CD140a)-APC (BioLegend) or containing anti-CD11c-FITC (BD Biosciences, San Jose, CA,
U.S.A.), anti-CD206-PerCP/Cy5.5 (BioLegend), and anti-F4/80-APC (BioLegend) for 30 min on
ice. After centrifugated at 1,000 × g for 10 min at 4°C, the supernatant
was discarded, and the pellet was suspended in PBS containing 2% FCS. The suspension was
filtered through a 40 µm nylon filter and analyzed on a flow cytometer
(BD FACSVerse, BD Biosciences) with singlet discrimination to detect APC, PE-Cy, PE, and
PerCP/Cy5.5 stained cells.

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.
