Pe conjugated cd133 antibody

Manufactured by BD

The PE-conjugated CD133 antibody is a laboratory reagent used for the detection and analysis of CD133-positive cells in various research applications. It is designed to bind specifically to the CD133 cell surface antigen, which is commonly used as a marker for various stem and progenitor cell populations. The PE (Phycoerythrin) fluorescent dye is conjugated to the antibody, allowing for the visualization and quantification of CD133-expressing cells using flow cytometry or other fluorescence-based techniques.

The levels of the CD44+, CD24 -, and CD133+cells in each group were evaluated using flow cytometry with a fluorescein isothiocyanate (FITC)-conjugated CD44 antibody (cat. no. 347943; BD Biosciences), phycoerythrin (PE)-conjugated CD24 antibody (cat. no. 555428; BD Biosciences), and a PE-conjugated CD133 antibody (cat. no. 12-1331-82; eBioscience; Thermo Fisher Scientific, Inc.). Mouse immunoglobulin (Ig)G2a-FITC (cat. no. 555573; BD Biosciences), mouse IgG2a-PE (cat. no. 554648; BD Biosciences), and mouse IgG1K-PE (cat. no. 12-4714-42; eBiosciences Thermo Fisher Scientific, Inc.) were used as the isotype controls (all of antibodies diluted at 1:100 ratio). Cells were incubated with antibodies at 4˚C for 45 minutes and analyzed using FACSCaliburTM (Becton Dickinson). The raw data were analyzed using Flowing Software version 2.5.0 (Perttu Terho).

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.
