Pe cy5 cd86

Manufactured by BioLegend
Sourced in United States

PE/Cy5-CD86 is a fluorescent-conjugated antibody that binds to the CD86 cell surface protein. CD86 is a co-stimulatory molecule expressed on antigen-presenting cells and plays a role in T cell activation. The PE/Cy5 fluorescent label allows for detection and analysis of CD86-expressing cells using flow cytometry.

Characterizing B Cell Subsets in SLE

To detect subpopulations and characterize phenotypes of B cells, PBMCs from SLE patients (n = 20) were separated and analyzed to determine the frequency of each B cell subset. Two × 105 cells were resuspended in 50 μl FACS buffer and incubated with surface antibodies for 15 min at 4 °C. Antibodies used included FITC-CD19, APC-CD21, APC/Fire750-CD27, Alexa/fluorro700-CD11c, PerCP/Cy5.5-CXCR5, PerCP/Cy5.5-IgG, PE/Cy7-IgD, APC-HLA-DR, PE/Cy5-CD69, and PE/Cy5-CD86 (Biolegend, San Diego, USA). After staining, cells were washed with 1 ml FACS buffer and resuspended in 300 μl FACS buffer for surface marker analyses.
The frequency and phenotype of DNA tetramer-binding B cells were detected by the tetramer staining technique, resuspended in 100 μl FACS buffer, and incubated with surface antibodies for 15 min at 4 °C. The stained B cells were washed with 1 ml FACS buffer and resuspended in 500 μl FACS buffer for flow cytometric surface marker analysis. FACS data were acquired with a BD FACS Canto II (Becton-Dickinson Immunocytometry Systems, San Jose, USA) and analyzed with FlowJo software (v. 10.0; Tree Star Inc., CA, USA).

Recombinant epidermal growth factor, Zombie Aqua Fixable Viability Kit, Alexa Fluor 488-EGFR, PerCP-Cy 5.5-CD3, PerCP-Cy 5.5-CD32 and PE-Cy5-CD86 flow antibodies were purchased from Biolegend (San Diego, CA). Cetuximab and panitumumab were purchased from the manufacturers, Bristol-Myers Squibb (New York, NY), and Amgen, (Thousand Oaks, California) respectively. FITC-CD69 and PE-Texas Red-CD8 flow antibody were purchased from Life Technologies (Grand Island, NY). PE-CD107a, PE-Cy5-CD137, PE-Cy7-CD16, APC-CD56, PE-CD32, APC-H7-HLA-A2 and FITC-CD80 flow antibodies were purchased from BD Biosciences (San Jose, CA). 12B6 antibody was produced by Dr. Ferrone (Harvard Medical School) and has been previously validated (14 (link)). PE-labeled HLA-A*0201-EGFR853-861 tetramer was provided by the NIH tetramer core facility and used for identification of EGFR-specific CTL (15 (link)). PE-Labeled HLA-A*02:01 HIV-tetramer was purchased from MBL International.

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.
