Pe conjugated anti siglec f e50 2440

Manufactured by BD
Sourced in United States

The PE-conjugated anti-Siglec-F (E50-2440) is a monoclonal antibody that binds to the Siglec-F receptor. Siglec-F is a member of the sialic acid-binding immunoglobulin-like lectin (Siglec) family and is expressed on eosinophils and a subset of alveolar macrophages. The PE (phycoerythrin) fluorescent label allows for detection and analysis of Siglec-F-expressing cells using flow cytometry.

The staining panel for immune cell subsets in BALF was designed according to previous studies [44 (link),45 (link)]. Briefly, the BALF cells were stained with fluorochrome-conjugated monoclonal antibodies at 4 °C for 30 min. The antibodies included FITC conjugated anti-Ly6G (1A8; BD Biosciences, San Jose, CA, USA), PE-conjugated anti-Siglec-F (E50-2440; BD Biosciences), APC-conjugated anti-B220 (RA3-6B2; BD Biosciences), APC-conjugated anti-CD3 (145-2C11; BD Biosciences), PerCP/Cy5.5-conjugated anti-CD11b (M1/70; BioLegend, San Diego, CA, USA), eFluor 450-conjugated anti-CD11c (N41B; Invitrogen, Eugene, OR, USA), and Live/Dead fixable Red (Invitrogen). After washing, the samples were analyzed with multi-parametric flow cytometry (LSR II; BD Boisciences) and data were analyzed with FlowJo software (version 10, Tree Star, Inc., Ashland, OR, USA).

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.
