Percp cy5.5 conjugated anti cd11b

Manufactured by BD
Sourced in United States

PerCP-Cy5.5-conjugated anti-CD11b is a fluorochrome-conjugated monoclonal antibody that binds to the CD11b cell surface antigen. CD11b is expressed on the surface of various immune cells, including monocytes, macrophages, and neutrophils. The PerCP-Cy5.5 fluorochrome allows for the detection and analysis of CD11b-positive cells using flow cytometry.

Multicolor flow cytometry was performed using standard procedures. Peripheral blood was drawn and blocked with an anti-CD16/CD32 (2.4G2; UCSF Cell Culture Facility) for 10 min. Without washing, the cells were then incubated with pre-mixed combinations of antibodies. FITC-conjugated anti-B220, anti-Ly6C, and anti-CD4; PE-conjugated anti-CD3e, anti-Ly6G, and anti-CD44; PE-Cy7-conjugated anti-NK1.1 and anti-CD8; PerCP-Cy5.5-conjugated anti-CD11b; APC-conjugated anti-CD45 and anti-CD62L antibodies were all purchased from BD Biosciences. Data were acquired on an Accuri C6 Flow Cytometer using CFlow Plus software (BD Biosciences) and analyzed with FlowJo (TreeStar Inc.) as previously described.18 (link)

Phagocytosis Assay of MC38 Cells

Check if the same lab product or an alternative is used in the 5 most similar protocols
For the phagocytosis assay, MC38 cells were treated with A3373 in DMEM containing 1% FBS for 48 h and were labeled with 2 μM carboxyfluorescein succinimidyl ester (CFSE). A total of 5 × 105 THP1 cells were incubated with equal numbers of CFSE-labeled cells in DMEM without FBS for 2 h in a 24-well plate. The cells were washed with PBS and incubated with human BD Fc block (BD Biosciences) to block nonspecific detection. Furthermore, the cells were incubated with PerCP-Cy5.5-conjugated anti-CD11b (BD Biosciences) for 20 min at 4 °C and were analyzed by flow cytometry.

Phenotypic Characterization of Blood Immune Cells

Check if the same lab product or an alternative is used in the 5 most similar protocols
Peripheral blood was collected in anticoagulated tubes, and mononuclear cells were isolated for further analysis. These cell samples were resuspended in RPMI 1640 and incubated in 5% CO 2 at 37 ℃ for 3 hours. All samples were detected on a FACS calibur analyser (Becton-Dickinson, Mountain View, CA).
Then, these cells were incubated with an Fcγ receptor-blocking mAb (CD16/32; BioLegend, San Diego, CA, USA) for 15 minutes at 4 °C. Subsequently, for surface antigen detection, the cells were shielded from light and labeled with with PE-conjugated anti-CD163 (1:100), PE-Cyanine7-conjugated anti-CD206 (Invitrogen, Calif., 1: 100), Alexa Fluor 488-conjugated anti-iNOS (Invitrogen, Calif., USA, 1: 200), PE/Cyanine7-conjugated anti-CD284 (Biolegend, Calif., USA, 1: 100), Alexa Fluor® 647-conjugated anti-F4/80 (BD Biosciences, Franklin Lakes, USA, 1: 100), PE-conjugated anti TIM-1 (BD Biosciences, Franklin Lakes, USA, 1: 100) and PerCP-Cy™5.5-conjugated anti-CD11b (BD Biosciences, Franklin Lakes, NJ, USA, 1: 100) antibodies. All data were analyzed using FlowJo 7.6.1 software (TreeStar, Ashland, OR, USA), and the inactive cells were excluded by gating.

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.
