Igma pe

Manufactured by BD

IgMa-PE is a fluorescently-labeled antibody designed for use in flow cytometry applications. It is a monoclonal antibody that specifically binds to the IgM surface antigen, which is expressed on certain types of B cells. The 'PE' in the name indicates that the antibody is conjugated to the fluorescent dye phycoerythrin.

Quantifying Peripheral B Cells After SpA Challenge

Check if the same lab product or an alternative is used in the 5 most similar protocols
To quantify the effect of SpA infusions on peripheral B cells, spleens were harvested 72 h post-SpA challenge and cell suspensions prepared, as described previously (43 (link), 46 (link), 56 (link)). Cells were maintained on ice throughout. For each mouse, 2 × 106 cells were stained per panel in the presence of 20 μg/ml of Fc block (Pharmingen, Becton Dickinson) followed by staining with: B220-APC (eBioscience), CD3-PerCP Cy5.5 (BD), IgMa-PE (BD) or IgMb-PE (BD). For live/dead cell discrimination, we used fixable blue (Invitrogen) following the manufacturer's instructions. After staining, cells were washed and fixed in 4% paraformaldehyde. At least 5 × 105 events per sample were collected on a LSR II flow cytometer (BD) running FACSDiva software. Data were analyzed with FlowJo (Treestar).

Multicolor Flow Cytometry Profiling of Pancreatic Immune Cells

Check if the same lab product or an alternative is used in the 5 most similar protocols
Single cell suspensions were prepared from resected pancreata using a gentleMACS Octo Dissociator with the Tumor Dissociation Kit as per the manufacturers’ instructions. Levels of the following cell surface markers were directly measured by flow cytometry on a BD FACSCanto (BD Biosciences) in two separate groups as noted and analyzed using FlowJo Software (Tree Star). Group 1: CD45 (APC; BioLegend), CD11b (PE/Cy7; BioLegend), Gr1 (PerCP; BioLegend), CD11c (PE; BioLegend), F4/80 (Alexa Fluor® 488; BioLegend), Fixable Viability Dye (eFluor™ 780; eBioscience) Group 2: CD45 (APC; BioLegend), Th1.2 (Alexa Fluor® 488; BioLegend), IgMa (PE; BD Pharmingen), CD4 (PE/Cy7; BioLegend), CD8a (PerCP; BD Pharmingen), Fixable Viability Dye (eFluor™ 780; eBioscience).

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.
