Pe conjugated anti cd146

Manufactured by Biocytex

PE-conjugated anti-CD146 is a monoclonal antibody that binds to the CD146 cell surface antigen. CD146 is a transmembrane glycoprotein involved in cell-cell adhesion. The PE (Phycoerythrin) fluorescent dye is conjugated to the antibody, enabling detection and quantification of CD146-expressing cells using flow cytometry.

Wild type or irradiation resistant Daoy or HD-MB03 cells (106 cells) were softly dissociated with 1X accutase (HyClone HyQTase, Fisher Scientific). The cells were then labeled with a mouse monoclonal PE-conjugated anti-CD146, (BioCytex, Marseille, FRANCE). Fluorescence was measured using the 488 and 633 nm lasers of a flow cytometer (FACS Canto - BD Biosciences, FRANCE). The gating strategy of these experiments is described in Supplementary Fig. S7. The data were collected with the BD FACSDiva software application. Percentages of CD146-labeled isolated cells were calculated with FlowJo® software version 18.0 (Flexera, Hamburg, GERMANY).

The cells were harvested as mentioned above and resuspended in PBS containing 1% FBS along with 0.5 mM EDTA. The cell suspension was incubated with specific antibodies for 1 h at 4°C. The following monoclonal antibodies were used: FITC (fluorescein isothiocyanate)-conjugated anti-CD 13 (ID Labs, # IDAC1071), FITC-conjugated anti-CD31 (Immunostep, # 31F-100T), FITC-conjugated anti-CD44 (BD Biosciences, # 560977), FITC-conjugated anti-CD 49b (BD Biosciences, # 555498), PE (phycoerythrin)-conjugated anti-CD 45 (BD Biosciences, # 555483) and PE-conjugated anti-CD146 (Biocytex, # 5050-PE100T). Thereafter, the cells were washed with PBS and fixed in 2% PFA. Analysis was performed on at least 10,000 events per sample using a FACS caliber flow cytometer (BD Biosciences). The acquisition was performed using CELLQUEST software (BD Biosciences) and analyzed using FCS-express software (DeNovo).

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.
